Description

  The present invention relates to a rinse-less electric razor cleaning agent used for cleaning shavings such as shavings accumulated in the blade portion of an electric razor, and an electric razor cleaning agent using the electric razor cleaning agent. It relates to a cleaning device.

  Since the electric razor has a structure in which shavings such as shavings and sebum are held in the blade portion of the head, it is necessary to periodically clean and clean. As a general cleaning method, there is a method of cleaning while driving an electric razor in tap water flowing from a faucet, but sebum etc. adhering to the blade is hydrophobic, so it is very easy to clean by repelling water It is difficult.

  Therefore, various surfactants and the like have been proposed as cleaning agents for electric razors. However, it is necessary to rinse with tap water after cleaning, and there is a problem that the cleaning is troublesome.

  Accordingly, a rinse-free electric razor cleaning agent based on water, which contains a surfactant and an oil component for the purpose of preventing rust and defoaming, which does not require rinsing with water, has been proposed (see Patent Document 1). ).

  However, the electric razor cleaning agent described in Patent Document 1 contains an oil component for the purpose of preventing rust and defoaming, but has a problem that it cannot provide lubricity to the driving portion of the blade of the electric razor. It was. That is, since the oil content of the cleaning agent of Patent Document 1 is unstable in emulsification, when the stirring is insufficient or stirring is not performed, the oil content is not uniformly dispersed in the cleaning agent. After the cleaning agent has dried and the appropriate amount of oil has adhered to the blade, the blade can be attached to the blade, and no oil will adhere to the blade, or the oil will not adhere to the blade. Can not do it. For this reason, the blade portion cannot be rust-prevented, and the blade drive portion cannot be given slidability. As a result, the sliding portion of the blade is baked, and there is a possibility that problems such as an increase in driving load may shorten the battery usage time or the motor life may be reduced.

Further, as a cleaning device for an electric razor, a cleaning device is provided in which a cleaning agent is circulated to clean the blade of the head of the electric razor (see, for example, Patent Document 2). Therefore, when the cleaning agent of Patent Document 1 is used in such a cleaning device, the oil component is easily separated from the cleaning agent, and the above-described problem appears remarkably.

  The present invention has been made in view of the above points, and can effectively clean shavings such as shavings and sebum collected on the blade of an electric razor without the need for rinsing. An object of the present invention is to provide a rinse-less electric razor cleaner and an electric razor cleaner that can provide a good sliding effect.

The cleaning agent for an electric razor according to claim 1 of the present invention contains water as a main component, contains a cleaning component, and a lubricating component compatible with water, and is based on the total amount of the cleaning agent. 80% by mass or more of water, 0.05 to 1% by mass of a cleaning component, 0.5 to 5% by mass of a lubricating component , and polyethylene glycol having an average molecular weight of 200 to 600 is used as the lubricating component. Is.

  According to this invention, since the lubricating component is compatible with the main component water, the lubricating component is uniformly dispersed / dissolved in the cleaning agent and the concentration distribution cannot be obtained, and the lubricating component is uniformly distributed on the blade portion. Can be adhered, and a good sliding effect can be stably given to the driving portion of the blade portion. Also, since it contains a lubricating component that is compatible with water, the cleaning component does not dissolve in the lubricating component even after drying, and the solid component of the cleaning agent does not precipitate on the surface of the blade, so it is rinsed with water. It is possible to effectively clean the shavings such as shavings and sebum collected on the blade of the electric razor with a cleaning component without rinsing.

The invention of claim 2 is characterized in that, in claim 1, the lubricating component does not volatilize at normal temperature and has a kinematic viscosity of 100 mm ² / s (under 25 ° C.) or less. .

Since the lubricating component does not volatilize, the lubricating component remains on the blade portion for a long period even after the electric razor is washed and dried, and the lubricating effect can be maintained for a long period. Furthermore, the lubricating component has a kinematic viscosity of 100 mm ² / s or less and does not become a burden when driving the blade portion of the electric razor, and can maintain a stable driving of the electric razor.

The invention of claim 3 is characterized in that, in claim 1 or 2 , the cleaning component is a nonionic surfactant.

  According to the present invention, it is possible to reduce the amount of cleaning components necessary for cleaning, and it is possible to reduce the influence of the cleaning components remaining on the blade portion after cleaning and drying on the slidability. .

The invention of claim 4 is characterized in that in any one of claims 1 to 3 , it contains a sterilizing component.

  According to the present invention, the lubricant component can be prevented from deteriorating due to various germs derived from shavings such as shavings and sebum, and when used in a washer that performs washing while circulating a cleaning agent. The deterioration of the cleaning agent due to various bacteria is suppressed, and the cleaning liquid can be used repeatedly for a long time.

The invention of claim 7 is characterized in that, in claim 4 , higher alcohol having 5 to 10 carbon atoms is contained as a sterilizing component.

  Higher alcohols that volatilize at room temperature exhibit high bactericidal properties and a broad bactericidal spectrum that resists most bacterial species even at low concentrations of sterilizing components, and are volatile after washing and drying electric razors. The skin irritation can be reduced because it does not remain on the blade. Also, higher alcohols, unlike lower alcohols, are less volatile than water, which is the main component, so even if water is evaporated repeatedly when used repeatedly in a washing machine that circulates cleaning agents, The composition ratio of the sterilizing component in the agent is not lowered, and the sterilizing performance can be maintained.

The invention of claim 8 resides in that in Claim 7, bactericidal component is characterized in that at least one of benzyl alcohol and phenoxyethanol.

An electric razor cleaner according to claim 9 of the present invention includes a tank storing the electric razor cleaning agent according to any one of claims 1 to 8, a cleaning tank for cleaning the electric razor, A filter that collects shavings such as shavings, and a pump that supplies the cleaning agent for the electric razor of the tank to the cleaning tank and returns the cleaning agent for the electric razor of the cleaning tank to the tank through the filter. It is what.

  According to this invention, the cleaning agent is not soiled by shavings, and the cleaning agent is circulated between the tank and the cleaning tank and can be used repeatedly over a long period of time.

  According to the present invention, it is possible to effectively clean shavings such as shavings and sebum collected on the blade of an electric razor with a cleaning component without rinsing with water, and without having to rinse. The lubricant component is uniformly dispersed / dissolved in it, the concentration distribution cannot be made, the lubricant component can be uniformly attached to the blade portion, and a stable sliding effect can be given to the drive portion of the blade portion. It can be done.

  Hereinafter, the best mode for carrying out the present invention will be described.

  The cleaning agent for an electric razor according to the present invention is formed by containing water as a main component and containing a cleaning component, a lubricating component, and, if necessary, a sterilizing component.

  The lubricating component used in the present invention is compatible with water. Lubricating components that are compatible with the main component water, which is the base material, can be uniformly dispersed and dissolved in the cleaning agent to prevent concentration distribution. When washing, the lubricating component can be uniformly attached to the blade portion, and a stable sliding effect can be given to the driving portion of the blade portion stably. Furthermore, an oleophilic lubricant that is not compatible with water may affect resin molded parts of electric razors, but such a problem is not possible with lubricating components that are compatible with water. There is nothing.

Further, it is desirable that the lubricating component does not evaporate at room temperature (use temperature of the cleaning agent: 25 ° C.) and has a kinematic viscosity (kinetic viscosity) of 100 mm ² / s (numerical value at 25 ° C.) or less. When the lubricating component does not volatilize at room temperature, the lubricating component remains on the blade portion for a long period of time after the electric razor is washed and dried, and the lubricating effect can be maintained for a long period of time. Is. Further, if the kinematic viscosity of the lubricating component exceeds 100 mm ² / s, there is a possibility that it becomes a burden when driving the blade portion of the electric razor, such being undesirable. By the way, when we investigated whether or not the electric razor motor was baked using lubricating components of various kinematic viscosities and an electric razor made by Matsushita Electric Works, it can be seen in the graph showing the relationship between the viscosity and the sliding property in FIG. In addition, the kinematic viscosity of the lubricating component needs to be 100 mm ² / s or less. The lower limit of the kinematic viscosity of the lubricating component is not limited, but if the kinematic viscosity is low, the lubricity is lowered, so that the lower limit is practically about 10 mm ² / s.

Surfactants may be mentioned as those having such lubricity (kinematic viscosity), but in nonionic surfactants, HLB (Hydrophilic-Lipophilic Balance) is 9 The above is preferable. If the HLB is less than 9, the hydrophobicity becomes strong and there is a possibility that the HLB is dispersed and separated without dissolving in water. The upper limit of the HLB is not particularly set, but about HLB13 is a practical upper limit. Such a nonionic surfactant having an HLB of 9 or more is not particularly limited, and among them, polyethylene glycol (PEG 200) having an average molecular weight of 200 and polyethylene glycol (PEG 300) having an average molecular weight of 300 are preferable. These are preferable in that they are excellent in lubricity, and are themselves a surfactant or a raw material for the surfactant, so that the cleaning performance is not lowered and the effective slidability can be maintained. is there. These may be used alone or in combination of two or more. And it is preferable to mix | blend a lubrication component in 0.5-5 mass% with respect to the whole quantity of a cleaning agent.

  Next, as the cleaning component used in the present invention, a nonionic surfactant is preferable. By using a non-ionic surfactant, it is possible to reduce the amount of cleaning components necessary for cleaning, and the cleaning components remaining on the blade slide after the electric razor is cleaned and dried. It is possible to reduce the influence on the property.

  The nonionic surfactant is not particularly limited as long as it is used for ordinary cleaning, and examples thereof include polyoxyethylene octylphenyl ether, polyoxyethylene alkyl ether, glycerin fatty acid ester, sorbitan fatty acid ester. And sucrose fatty acid esters. In particular, water-soluble nonionic surfactants that emulsify the shavings sebum are preferred, and those having an HLB of 9 to 13 are particularly preferred. As an example, polyoxyethylene octylphenyl ether can be mentioned, and those having a polymerization degree of 7 to 12 are preferred.

  One or more of the above-mentioned nonionic surfactants can be used, and the blending amount is in the range of 0.05 to 1% by weight, particularly 0.1 to 0.00%, based on the total amount of the cleaning agent. The range of 5% by mass is preferable because it is excellent in the detergency and foaming property of the shavings and sebum adhering to the blade portion of the electric razor. In addition, when a nonionic surfactant having a high viscosity is used in order to maintain good lubricity by the cleaning agent, the addition amount of the nonionic surfactant is equal to or less than the addition amount of the lubricity component. In particular, the range of 1/10 to 1/2 of the amount of lubrication added is preferable.

  In the present invention, the sterilizing component (antibacterial component) is non-volatile at room temperature (cleaning agent use temperature: 25 ° C.) or volatile at room temperature (cleaning agent use temperature: 25 ° C.). be able to.

  The non-volatile sterilizing component at room temperature remains in the blade portion at a high concentration even after cleaning with an electric razor and drying with a cleaning agent, and maintains high sterility on the surface of the blade portion for a long time. It is something that can be done. Here, the term “nonvolatile” means that it does not volatilize in a normal temperature environment, or that evaporation and sublimation hardly occur. As such a non-volatile sterilizing component, cetylpyridinium chloride, isopropyl Examples thereof include methylphenol, p-hydroxybenzoate ester, triclosan, polylysine, sodium benzoate, gluconesan chlorhexidine, resorcin, and thymol. These may be used alone or in combination. Among these, cetylpyridinium chloride, isopropylmethylphenol, p-hydroxybenzoate, polylysine, and triclosan can be dissolved in the lubricating component even after washing and drying the electric razor, and the effect of the lubricating component on lubricity This is particularly preferable because it can be made small and is less influenced by the presence of the surfactant. It is more preferable to use these in combination with the above other sterilizing components mainly as a sterilizing component. Since the non-volatile sterilizing component needs to be dissolved in the lubricating component even after the electric razor is washed with a cleaning agent and dried, the addition amount must be set to be equal to or less than the dissolved amount in the lubricating component.

  On the other hand, higher alcohol is used in the present invention as a volatile sterilizing component at room temperature, and this exhibits a high sterilizing property and a broad sterilizing spectrum that opposes most bacterial species even at a low concentration of sterilizing component. Moreover, since it volatilizes after washing and drying the electric razor, it does not remain on the blade portion, and the skin irritation can be reduced. Also, higher alcohols, unlike lower alcohols, are less volatile than water, which is the main component, so even if water is evaporated repeatedly when used repeatedly in a washing machine that circulates cleaning agents, The composition ratio of the sterilizing component in the agent is not lowered, and the sterilizing performance can be maintained.

  As the higher alcohol, those having 5 to 10 carbon atoms are preferable, and benzyl alcohol and phenoxyethanol are particularly preferable. These can be used alone or in combination. Since these have high lubricity, they can eliminate the effect on the slidability of the blade part before drying, and they are safe for use in cosmetics. It is expensive, inexpensive and stable in quality. Moreover, although these vapor pressures are small, they are gradually volatilized in a room temperature environment, so it is preferable to use them together with a non-volatile bactericide.

  The sterilizing component is composed of the above-mentioned non-volatile substances and volatile substances, but either one may be used alone or both may be used together, but the blending amount is the total amount of the cleaning agent The range of 0.05-5 mass% is preferable.

  An electric razor cleaning agent can be prepared by mixing and mixing the above components, and the amount of water as a main component is 80 to 99.5% by mass relative to the total amount of the cleaning agent. A range is preferred. In the present invention, the cleaning agent is a combination of a cleaning component, a lubricating component, and a sterilizing component in water. As an aspect of providing the cleaning agent, each component is mixed in water at a predetermined concentration. In addition to providing the product, it is also possible to provide a mixture of each component at a high concentration and dilute it with water to a predetermined concentration before use. In the case of providing a high-concentration mixture, it is held in a concentrated liquid form, a filter impregnated with a concentrated liquid, an adsorbed form on a hygroscopic polymer, a solid tablet form, or a soluble capsule. The provided form is not limited to the provision form.

  FIG. 1 shows an example of a cleaning device for cleaning the blade portion 9 of the electric razor 3 using the cleaning agent for an electric razor according to the present invention, and a tank for storing the cleaning agent 1. 2, a cleaning tank 4 for cleaning the electric razor 3, a filter 5 for collecting shavings such as shavings, and a cleaning agent 1 in the tank 2 are supplied to the cleaning tank 4, and a cleaning agent in the cleaning tank 4 And a pump 6 for returning 1 to the tank 2 through the filter 5.

  In the upper part of the tank 2, a sealable inlet 10 for introducing and discharging the cleaning agent 1 and an opening / closing port 12 provided with an airtight valve 11 formed of an electromagnetic valve or the like are formed. A supply path 13 is connected between the tank 2 and the cleaning tank 4. The supply path 13 is bent upward so that one end opens at the bottom below the liquid level of the cleaning agent 1 in the tank 2 and the middle path is positioned above the liquid level of the cleaning agent 1 in the tank 2. At the same time, the other end is formed by a pipe connected to the cleaning tank 4 at a position above the liquid surface of the cleaning agent 1 supplied to the cleaning tank 4. A fixing base 14 for fixing the electric razor 3 is provided in the cleaning tank 4, and a drying fan 15 is disposed above the side portion of the cleaning tank 4.

  A filter 5 is disposed below the cleaning tank 4. The filter 5 is formed by providing a filtration membrane 17 in the filtration chamber 16 that divides the inside of the filtration chamber 16 up and down, and an upper chamber 16 a above the filtration membrane 17 of the filtration chamber 16 of the cleaning tank 4 and the filter 5. Are connected by a transfer channel 18. The filtration membrane 17 is formed of a nonwoven fabric or the like, but can also be formed of a mesh or the like. A recovery path 19 is connected between the tank 2 and the filter 5. The recovery path 19 is formed by a pipe having one end connected above the liquid surface of the cleaning agent 1 in the tank 2 and the other end connected to the lower chamber 16 b below the filter membrane 17 of the filter chamber 16 of the filter 5. Is. The liquid feed pump 6 is connected in the middle of the recovery path 19.

  In cleaning the blade portion 9 of the electric razor 3 with the cleaning device formed as described above, the electric razor 3 is first positioned in the cleaning tank 4 with the blade portion 9 of the head of the electric razor 3 positioned by the fixing base 14. Is set in the washing tank 4. At this time, the cleaning agent 1 is not yet supplied to the cleaning tank 4. When the cleaning device is turned on, the airtight valve 11 is closed and the pump 6 is activated. When the airtight valve 11 is closed in this manner, the opening / closing port 12 is closed and the inside of the tank 2 is in an airtight state, and since the cleaning agent 1 does not exist at the location of the pump 6, the pump 6 sends air into the tank 2. It will be. Accordingly, since the pressure in the sealed tank 2 is higher than the atmospheric pressure, the cleaning agent 1 in the tank 2 is sent out to the supply path 13 by this pressure, and the cleaning agent 1 is washed through the supply path 13 as indicated by the arrow B. It is supplied to the tank 4. When the cleaning tank 1 is filled with a certain amount of the cleaning agent 1, the pump 6 stops. In the meantime, the electric razor 3 is preferably kept in a driving state, and the blade portion 9 of the head can be cleaned with the cleaning agent 1 in the cleaning tank 4.

  When a predetermined time elapses, the airtight valve 11 is opened, the opening / closing port 12 is opened, and the pump 6 is operated again. The cleaning agent 1 in the cleaning tank 4 is returned to the tank 2 and collected by the pump 6. The cleaning agent 1 in the cleaning tank 4 enters the upper chamber 16a of the filtration chamber 16 of the filter 5 from the transfer channel 18 as indicated by the arrow B, passes through the filtration membrane 17 and is transferred to the lower chamber 16b, and then as indicated by the arrow C. In addition, it is returned to the tank 2 through the recovery path 19 and recovered. In this way, when the cleaning agent 1 in the cleaning tank 4 passes through the filter 5, shavings such as sawdust mixed in the cleaning agent 1 when cleaning the blade portion 9 of the electric razor 3 are filtered membrane of the filter 5. The cleaning agent 1 can be recovered in the tank 2 in the state of being filtered and cleaned at 17. Further, since the inside of the tank 2 is opened by opening the airtight valve 11, even if the cleaning agent 1 flows into the tank 2, the pressure inside the tank 2 does not become higher than the atmospheric pressure. The cleaning agent 1 is not sent to the supply path 13 and supplied to the cleaning tank 4. Accordingly, the entire amount of the cleaning agent 1 in the cleaning tank 4 is returned to the tank 2, and the cleaning agent 1 in the cleaning tank 4 is emptied. When the cleaning agent 1 in the cleaning tank 4 becomes empty, the pump 6 is stopped. To do.

  Then, one cycle of cleaning is completed by the operation from supplying the cleaning agent 1 from the tank 2 to the cleaning tank 4 until the cleaning agent 1 in the cleaning tank 4 is recovered. Usually, this cycle is repeated three times for cleaning, but of course, the number of cycles is not limited. When the cleaning is completed, the fan 15 is operated, and the blade 9 of the electric razor 3 set in the cleaning tank 4 is blown and dried. The fan 15 stops when a predetermined time has elapsed, and cleaning is completed by a series of these operations. In the embodiment of FIG. 1, the fan 15 is provided for drying, but the presence or absence of drying is not particularly limited.

  Next, the present invention will be specifically described with reference to examples.

Example 1
An electric razor cleaning agent was prepared by mixing each component of the following composition. The kinematic viscosity of the lubricating component polyethylene glycol (average molecular weight 200) is about 50 mm ² / s (25 ° C.).

(Ingredient) (mass%)
・ Polyoxyethylene octyl phenyl ether 0.25
(Degree of polymerization of oxyethylene 9)
・ EDTA (ethylenediaminetetraacetic acid) 0.01
-Polyethylene glycol (average molecular weight 200) 1.0
-Cetylpyridinium chloride 0.1
・ Benzyl alcohol 3.0
・ Pure water 95.64
(Example 2)
In the composition of Example 1, polyethylene glycol (average molecular weight 600) having a kinematic viscosity of about 150 mm ² / s (25 ° C.) is used instead of the lubricating component polyethylene glycol (average molecular weight 200). An electric razor cleaning agent was prepared at the same composition ratio as in Example 1.

(Comparative Example 1)
In the composition of Example 1, the water-insoluble liquid paraffin (kinematic viscosity 12.4 mm ² / s (25 ° C.)) was used in place of the lubricating component polyethylene glycol (average molecular weight 200). An electric razor cleaning agent was prepared at the same composition ratio as 1.

(Evaluation Method 1: Drive State)
200 ml of electric razor cleaning agent was placed in a 500 ml beaker, the blade of the electric razor was immersed in the cleaning agent, and forcedly dried with hot air at 40 ° C. And after drying, each electric razor was continuously driven for 5 minutes, and the presence or absence of the burning of a motor and abnormality of a drive sound was observed. Then, it was determined that “◯” indicates that the motor is driven normally, “Δ” indicates that the motor drive sound is abnormal, and “X” indicates that the motor is burned.

The evaluation method 1 was tested using the cleaning agents for electric razors of Examples 1 and 2 and Comparative Example 1, and the determination results are shown in Table 1. In Example 1, the lubricating component polyethylene glycol (average molecular weight 200) has a kinematic viscosity of about 50 mm ² / s, and does not volatilize after drying at 40 ° C., and the sliding portion of the blade of the electric razor Therefore, good slidability was maintained during driving for 5 minutes. On the other hand, in Example 2, polyethylene glycol (average molecular weight 600) has a kinematic viscosity of 100 mm ² / s or more, an abnormal noise of the motor is generated, and the kinematic viscosity of the lubricating component is less than 100 mm ² / s. Was confirmed to be desirable. Moreover, in the thing of the comparative example 1, although liquid paraffin has low kinematic viscosity, since it is almost insoluble in water, it isolate | separates in a cleaning agent and is hard to be supplied to the blade part of an electric razor. In particular, in the cleaning device of FIG. 2, the liquid paraffin is separated in the cleaning agent in the tank, and the cleaning agent supplied to the cleaning tank does not contain sufficient liquid paraffin, and the blade of the electric razor The lubricating component is not supplied to the part. For this reason, in the thing of the comparative example 1, the sliding resistance of a blade part became large, the motor was overloaded, and baking occurred.

(Example 3)
In the composition of Example 1, a cleaning agent for an electric razor was prepared at the same composition ratio as Example 1, except that the cleaning component polyoxyethylene octylphenyl ether was changed to one having a polymerization degree of oxyethylene of 5. .

Example 4
The composition of Example 1 is the same as Example 1 except that the nonionic surfactant polyoxyethylene octylphenyl ether, which is a cleaning component, is changed to the anionic surfactant sodium stearate. An electric razor cleaning agent was prepared at a composition ratio.

(Example 5)
An electric razor cleaning agent was prepared by mixing each component of the following composition.

(Ingredient) (mass%)
・ Sodium stearate 1.0
・ EDTA (ethylenediaminetetraacetic acid) 0.01
-Polyethylene glycol (average molecular weight 200) 1.0
-Cetylpyridinium chloride 0.1
・ Benzyl alcohol 3.0
・ Pure water 94.89
(Example 6)
An electric razor cleaning agent was prepared by mixing each component of the following composition.

(Ingredient) (mass%)
・ Sodium stearate 3.0
・ EDTA (ethylenediaminetetraacetic acid) 0.01
-Polyethylene glycol (average molecular weight 200) 1.0
-Cetylpyridinium chloride 0.1
・ Benzyl alcohol 3.0
・ Pure water 92.89
(Evaluation method 2: driving state and cleaning state)
We prepared 5 electric razors, selected 20 monitors with the same darkness, and asked 4 people to shave their razors for each electric razor. Then, 100 ml of an electric razor cleaning agent was added to the cleaning device of FIG. 2, and the blade of the electric razor was cleaned and dried. With respect to the electric razor thus cleaned and dried, the driving state of the motor was observed, and the internal / external cleaning state of the blade portion of the electric razor was visually observed by 10 specialist panelists. Regarding the drive state, it was determined that “◯” indicates that the motor is normally driven, “Δ” indicates that the motor drive sound is abnormal, and “X” indicates that the motor is burned. As for the cleaning state, “3” indicates that no dust is attached to the inside or outside of the blade on each panel, and “2” indicates that the dust is slightly attached to the inside or outside of the blade. If you have a lot of sawdust on the inside / outside of the blade, score it as “1”, find the average score, get an average score of 2.5 or more, “○”, average score 1.5 ~ 2.4 was judged as “Δ”, and an average score of 1.4 or less was judged as “x”.

  Using the electric razor cleaning agents of Examples 1 and 3 to 6, the evaluation method 2 was tested, and the determination results are shown in Table 2. In Examples 1 and 3, since the concentration of the cleaning component is low, there is no influence on the slidability and the driving state is good, and the cleaning component is a nonionic interface even though the concentration of the cleaning component is low. Since it is an activator, the cleaning condition was also very good. On the other hand, in the case where sodium stearate which is an anionic surfactant is used as a cleaning component, the driving state is good because the concentration is low in Example 4 because the concentration is low. A lot of sawdust was attached and it was bad. In Examples 5 and 6, the concentration of sodium stearate is increased, and the cleaning state is improved as the concentration is increased, but the sliding property is reduced and abnormal noise is generated in the motor. Yes. Accordingly, it is confirmed that a nonionic surfactant having a low concentration and a high detergency is excellent as a detergency component in an electric razor detergent composed mainly of water and comprising a detergency component and a lubrication component.

(Example 7)
An electric razor cleaning agent was prepared by mixing each component of the following composition.

(Ingredient) (mass%)
・ Polyoxyethylene octyl phenyl ether 0.25

-Polyethylene glycol (average molecular weight 200) 1.0
-Cetylpyridinium chloride 0.1
・ Pure water 98.64
(Example 8)
In the composition of Example 7, an electric razor cleaning agent was prepared at the same composition ratio as Example 7 except that cetylpyridinium chloride, which is a bactericidal component, was changed to polylysine.

(Ingredient) (mass%)
・ Polyoxyethylene octyl phenyl ether 0.25
(Degree of polymerization of oxyethylene 9)
・ EDTA (ethylenediaminetetraacetic acid) 0.01
-Polyethylene glycol (average molecular weight 200) 1.0
・ Ethyl alcohol 40.0
・ Pure water 58.74
(Evaluation method 3: Sterilization state)
Twenty electric razors were prepared, 20 monitors with similar heel density were selected, and each monitor used one electric razor to shave the heels for one month. Then, 100 ml of an electric razor cleaning agent was added to the cleaning device of FIG. 2, and the blade portion of the electric razor was cleaned and dried every day. And 24 hours after washing and drying every week, wipe the inside and outside of the blade part of the electric razor with sterilized absorbent cotton, suspend it in sterilized water, and adhere to the electric razor with a blood agar medium. The number of sterilizations was measured. In addition, the value of the number of bacteria was calculated | required as an arithmetic average of four evaluation results using the same cleaning agent.

  Using the electric razor cleaning agents of Examples 7 to 10, the evaluation method 3 was tested, and the determination results are shown in Table 3. In Examples 7 to 9, steril pyridinium chloride, ethyl parahydroxybenzoate, and propyl parahydroxybenzoate, which are bactericidal components, are all non-volatile and dissolve in polyethylene glycol, which is a lubricating component, without scattering. The sterilization is maintained for a long time, and the concentration of the sterilizing component on the surface of the blade of the electric razor is significantly increased by drying after washing. It was possible to suppress the breeding. On the other hand, since ethyl alcohol, which is a sterilizing component of Example 10, is highly volatile at room temperature, bacteria were not detected after one week, but as the number of washings increased, ethyl alcohol evaporated, Nutrient sources such as sebum in the cleaning agent increase and they remain inside and outside the blade of the electric razor along with the lubricating components, etc. there were.

(Example 11)
An electric razor cleaning agent was prepared by mixing each component of the following composition.

(Ingredient) (mass%)
・ Polyoxyethylene octyl phenyl ether 0.25
(Degree of polymerization of oxyethylene 9)
・ EDTA (ethylenediaminetetraacetic acid) 0.01
-Polyethylene glycol (average molecular weight 200) 1.0
・ Benzyl alcohol 3.0
・ Pure water 95.74
(Evaluation Method 4: Sterilized State)
Eight electric razors were prepared, eight monitors with the same darkness were selected, and each monitor used one electric razor to shave the heels for one month. Then, 100 ml of an electric razor cleaning agent was added to the cleaning device of FIG. 2, and the blade portion of the electric razor was cleaned and dried every day. Then, after washing and drying every week, the washing liquid in the tank was collected 24 hours later, and the number of sterilizations was measured using a blood agar medium. In addition, the value of the number of bacteria was calculated | required as an arithmetic average of four evaluation results using the same cleaning agent. Further, the presence of bacteria in the blade portion of the electric razor 24 hours after washing and drying was evaluated by the same wiping test as in Evaluation Method 3.

  The evaluation method 4 was tested using the electric razor cleaners of Example 11 and Example 10, and the determination results are shown in Table 4. In Example 11, since benzyl alcohol, which is less volatile than water, is used as a sterilizing component, high sterility is maintained even after washing and drying for 4 weeks. On the other hand, since ethyl alcohol which is a sterilizing component of Example 10 has high volatility, the initial sterilization property maintains high bactericidal properties. However, by repeating washing and drying, ethyl alcohol in the cleaning liquid evaporates and is initially As a result, the propagation of various bacteria was confirmed from the third week onward, and the presence of bacteria in the blade of the electric razor 24 hours after washing and drying was observed in both Example 11 and Example 10. It was not detected.

It is a schematic sectional drawing which shows an example of the washing device for electric razors which concerns on this invention. It is a graph which shows the relationship between the viscosity of a lubrication component, and lubricity.
