Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applied to the skin surface to an appropriate thickness and dried after a certain period of time to soften the stratum corneum of the skin and give appropriate tension to the skin. The present invention relates to a so-called film-type pack agent, which is a cosmetic that can increase temperature, improve blood circulation, and when a formed film is peeled off, can remove dirt on the skin and exhibit a cleaning effect.

More specifically, it can be easily and evenly applied, dries appropriately in a short time, forms a beautiful white film that is easy to peel off, and is uniform and easy to peel off without causing pain to the skin. This invention relates to a film-type pack with good storage stability, which can give a moist and good feeling to the skin afterwards. Conventionally, the requirements for film-type packs are: 1) High safety without irritating the skin.

■ It can be applied easily and evenly, and forms a homogeneous film after proper drying. '3' Is the peeling time of the formed film short? It must be easy and uniform.

{4' Able to give a moist and good feel to the skin from which the film has been removed.

[51 Good storage stability (stability over time).

However, there are almost no film-type packs on the market that can satisfy these conditions. In conventional commercially available packs that use polyvinyl alcohol to form a film, the adhesion of the polyvinyl alcohol film to the skin is too strong, making it difficult to peel off uniformly and causing pain to the skin when the film is pulled off. There are some easy drawbacks.

Furthermore, this film-type pack agent has the drawback that it takes a long time to form a peelable film, and attempts have been made to improve this drawback by increasing the concentration of polyvinyl alcohol or adding metal powders. However, it has the disadvantage of not being able to be applied evenly and lacking in moisturizing properties.
On the other hand, attempts have been made to shorten the film formation time by using latex of natural rubber or synthetic rubber at high concentrations as a film-forming agent, but the film of such packs has a low modulus and Due to the strong adhesion (adhesive force) to the skin, it causes a high degree of elongation, which is characteristic of rubber, when peeled off, making it difficult to peel off uniformly, and when the rubber pieces contract due to stretching and cutting, directly hit the skin surface, causing intense pain. There are drawbacks such as.

Furthermore, since pack agents using latex of natural rubber or synthetic rubber generally tend to produce a film with an uneven appearance (for example, spots), attempts have been made to form a uniform white film by mixing certain pigments. However, the pigments tend to aggregate and it is very difficult to mix them stably. The present invention is a Z product that has completely improved the above-mentioned glazing technology, and its purpose is to provide a uniformly beautiful white color that can be easily and uniformly applied, dried appropriately in a short period of time, and easily peeled off. Film-type packs have good storage stability and can be peeled off uniformly and easily without causing any pain on the skin, giving a good moist feel to the skin after peeling off. It is about providing.

That is, the present invention comprises as main constituents at least one water-soluble polymer selected from the group consisting of unvulcanized synthetic rubber latex, polyvinyl alcohol, and free acid type carboxyvinyl polymer, and the surface of the pigment. is a processed pigment coated with an oily substance, a nonionic surfactant or a nonionic surfactant and an anionic surfactant, and water, and the amount of the processed pigment is 0.
．． It is a film-type pack agent in which the amount of nonionic surfactant or nonionic surfactant and anionic surfactant is 0.5 to 10% by weight.

Hereinafter, embodiments of the present invention will be explained in detail.

3 The processed pigment used in the present invention whose surface is coated with an oily substance is obtained by treating a normal pigment commonly used in cosmetics with an emulsion or solution of an oily substance to substantially coat the surface of the pigment with an oily substance. It is a processed pigment that is evenly adhered (adsorbed). 3. Therefore, the surface of the base pigment in this processed pigment is substantially covered with an oily substance. The amount of the oily substance adhering to (coating the surface of) the base pigment in this processed pigment is preferably 0.2 to 5% by weight based on the weight of the base pigment. Examples of the base pigment of the processed pigment include titanium oxide, talc,
Kaolin, zinc oxide, calcium carbonate, etc. are preferred. Oily substances attached to the pigment surface of the substrate include, for example, higher fatty acid hydrocarbons, vegetable oils, animal oils, waxes, higher fatty acids, higher alcohols, ester oils, silicone oils, etc., which are substantially insoluble in water. Examples include sticky oily substances (oily substances for cosmetics). Examples of the higher aliphatic hydrocarbons include liquid paraffin, squalane, and ceresin; vegetable oils include avocado oil and olive oil; animal oils include turtle oil and mink oil; and waxes include millet oil and shark oil. Examples of higher fatty acids include stearic acid and valmitic acid; examples of higher alcohols include isop-d-pyl myristate and octyldodecyl myristate; and examples of silicone oils include dimethylsiloxane and methylphenylpolysiloxane. . A method for producing a processed pigment in which the surface of the pigment is coated with an oily substance is, for example, by uniformly dispersing the pigment in inpropyl alcohol, adding an oily substance, mixing, and then adding water.
There is a method in which an oil-based substance is uniformly adsorbed onto the pigment surface and then dried, or a pigment is uniformly mixed and dispersed in an emulsion of an oil-based substance, and the emulsion is scale-emulsified (destroying the emulsion) to form a surface of the pigment. Examples include a method in which an oily substance is adsorbed on the surface of the wafer, followed by drying. The blending amount of the processed pigment in the pack agent of the present invention is 0.1 to 1% by weight, preferably 0.5 to 8% by weight, based on the total amount of the formulation (packing agent composition).

If the amount is less than 0.1% by weight, the time required to form a removable film will be longer, and a pack with an uneven appearance (for example, uneven spots) will be formed, and the film will not be able to be peeled off homogeneously. No, I don't like it.

When the amount exceeds 1% by weight, the viscosity of the pack agent increases significantly, making it difficult to apply uniformly, and the long-term storage stability becomes weak, resulting in easy agglomeration, which is undesirable.

Examples of nonionic surfactants to be incorporated into the pack agent of the present invention include sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene fatty acid ester, polyoxyethylene alkyl ether, and polyoxyethylene alkyl allyl ether. Tel etc. are preferred.

Preferred examples of the anionic surfactant include fatty acid soaps, higher alcohol sulfate ester salts, polyoxyethylene alkyl ether sulfates, polyoxyethylene alkyl ether phosphates and their salts. Usually, these surfactants are used alone or in combination of two or more.

The amount of such surfactant used is 0.5 to 1% by weight, preferably 1.0 to 8% by weight, based on the total amount of the formulation.
% by weight.

If it is less than 0.5% by weight, the stability will decrease, processed pigments and polymer particles will aggregate and become non-uniform during long-term storage, and the drying rate will be slow and the time required to form a peelable film will increase. , the peelability of the film becomes weak and cannot be peeled off easily and uniformly.

Moreover, if the amount exceeds 1% by weight, the stability decreases, and when stored for a long period of time, it aggregates and becomes non-uniform, and the releasability becomes poor, which is not preferable. Unvulcanized synthetic rubber latte applicable to the present invention. As the rubber, for example, isoprene rubber, styrene-butadiene rubber, butadiene rubber, etc. are preferable. The blending amount of the unwashed synthetic rubber latex is 30 to 65% by weight, preferably 40 to 6% by weight, based on the total amount of the formulation as a dry solid content of the synthetic rubber latex. When the amount is less than 3% by weight, the viscosity of the pack agent becomes low and it may be difficult to apply it, and the time required to form a peelable film becomes longer, and the film forming ability and peelability of the film tend to decrease.

Moreover, if the amount exceeds 65% by weight, the viscosity of the pack agent increases, making it difficult to apply it uniformly. The water-soluble polymer used in the pack agent of the present invention is polyvinyl alcohol or free acid type carboxyvinyl polymer.

These water-soluble polymers may be used alone or in combination. The amount of such water bathing polymer used is 0.01 to 15% by weight, preferably 0.05 to 10% by weight, based on the total amount of the formulation. When the amount is less than 0.01% by weight, storage stability tends to deteriorate, and when it is more than 15% by weight, the time required to form a peelable film becomes longer, and uniform coating tends to become difficult.

The amount of water incorporated is from 35 to 8% by weight, preferably from 40 to 7% by weight, based on the total amount of the formulation.

The pack agent according to the present invention, which is made by blending the above-mentioned components as described above, gives a moist and good feel to the skin after the pack film is peeled off, but it also contains liquid polyhydric alcohol in an amount of at most 15% by weight ( By blending (preferably 2 to 8% by weight), a moister and better feel can be provided.

The liquid polyhydric alcohol is an alcohol that has two or more hydroxyl groups and is liquid and easily soluble in water, such as propylene glycol, glycerin, diglycerin, and polyethylene glycol having a molecular weight of 200 to 600.

Commonly used ingredients that can be incorporated into the pack agent of the present invention include perfume preservatives, dyes, cosmetic medicinal ingredients, and the like. If necessary, a small amount of a neutralizing agent such as an acidic substance or a basic substance, or a P-regulator may be added within a range that does not impede the above-mentioned effects of the present invention.

The film-type pack of the present invention is in the form of a homogeneous liquid or paste and has excellent storage stability.
It spreads easily, can be applied evenly, and dries appropriately in a short time, forming a film that is extremely easy to peel off and has a uniform and beautiful color (white if not colored), and can be applied circularly without causing pain to the skin. It peels off easily and leaves the skin feeling moisturized after peeling off.
It is an excellent pack agent and its effects are remarkable.

Examples of the present invention will be described below.

Parts in the examples mean % by weight.

The details of the peelable film formation time (hereinafter referred to as peeling time), peelability, and stability, which are characteristics of Pacta agent, were determined by the method shown below, and other characteristics were determined by practical tests conducted by three specialized inspectors. (elongation during application, ease of peeling, moist feel), appearance of the formed film, and long-term storage stability. {1' Peeling time: Apply the film-type pack to an area of 3c x 3c on the flexor side of the forearm to a uniform thickness of 0.5 ta, and wait until the pack forms a uniform film. The time required for uniform peeling was also measured.

When the peeling time was 7 minutes to 15 minutes, it was evaluated as good (easy to use), and when the peeling time was less than 7 minutes or more than 15 minutes, it was evaluated as poor (difficult to use).

0 (2) Peelability test (peel stress) B treated with purified water on a 76-rib x 26-rib slide glass
URN TREATMENT SKINBANK Co., Ltd.'s freeze-dried skin (Lyoderm) was pasted on it, a sample pack agent was applied on it to an even thickness, and the humidity was 75°C.
% room for 3 hours.

Next, the film was left in a humidifier at room temperature and humidity of 75% for 1 hour, and the peel stress was measured using a rheometer at a peel rate of 0.6 ribs/second. If the peeling stress is less than 5 ta, it is good (easy to peel). If it was 5 to 10 ta, it was considered poor (young peeling occurred), and if it was 10 ta or more, it was considered poor (difficult to peel and felt pain).

'31 Stability evaluation (judgment in a short time) Approximately 10 samples were placed in a glass centrifuge tube with a volume of 15' and placed in a tabletop low-medium Liao centrifuge (H-10 Kari type) manufactured by Z Domestic Centrifuge Co., Ltd. Using 45q0300 enemies. p. Perform a centrifugal separation test for 15 minutes under the conditions of m to determine the ratio of the volume of the cream phase after centrifugation to the volume of the cream phase (uniformly emulsified and dispersed phase) of the sample.

The closer this volume ratio is to 1, the more stable it is ~ 0.98~1.00
The proportion is stable, and when it is smaller than 0.98, it is considered to be unstable. Example 1 To 91.7 parts of unvulcanized polyisobrene rubber latex emulsion (dry solids concentration 60%), 3 parts of polyoxyethylene nonyl phenyl ether (bivalent .0.) was added. , I worshiped the candles until it became uniform.

This mixture will be referred to as liquid A. Next, on the other hand, 2 parts of sorbitan monooleate was added with 2 parts of free acid type carboxyvinyl polymer (2 parts of sorbitan monooleate).
% aqueous dispersion) 7 parts, a processed pigment in which the surface of titanium oxide is coated with octyldodecyl myristate (hereinafter abbreviated as ODM) (ODM adhesion amount is 3.8 parts based on the weight of titanium oxide)
0%), 4.5 parts of water, and 0.1 part of triethanolamine were added and mixed. This mixture will be referred to as liquid B.
Next, Solution A was gradually added to Solution B while stirring, and both solutions were mixed uniformly to obtain a film-type pack agent of the present invention having a pH of 7.0.

When the peeling time of this pack agent was examined, it was found that it could be peeled off uniformly in 11 minutes.

Next, the peel stress was examined by a peel test, and it was found that the film could be peeled off uniformly in 1.8 hours. Further stability evaluation revealed that the product was stable at a cream phase volume ratio of 1.0. Furthermore, this pack spreads easily and can be applied easily and uniformly, and when a film is formed, it forms a white, uniform film, and can be easily and uniformly peeled off without irritating the skin. In addition, as a result of storing this pack for 6 months within the range of 0 to 45℃,
The appearance was the same as that immediately after production, and no discoloration, separation, or aggregation was observed.

As described above, the film-type pack agent of the present invention is extremely good, and is significantly superior to pack agents according to comparative examples described below.

Comparative Example 1 The same procedure as in Example 1 was carried out, except that 91.7 parts of natural rubber latex (dry solids concentration 60%) was used instead of unvulcanized polyisoprene rubber latex.

As a result, the obtained film-type backing agent had a pH of 7.3, and when the peeling time was measured in the same manner as in Example 1, the pH was 12.
I was able to peel it off evenly in minutes.

Next, when the peel stress was examined, it was found to be 4.5 days, but uniform peeling could not be achieved.

Furthermore, when stability was evaluated, the stability was poor at a cream phase volume ratio of 0.90.

In addition, the ammonia odor was somewhat strong, and there was some partial aggregation immediately after production. Furthermore, as in Example 1, 0 to 45o
As a result of storage for 6 months within the temperature range of 0, those stored at a temperature of 30 qo or higher turned yellow, the odor changed significantly, and some aggregation was observed.

Comparative Example 2 A comparative pack agent was prepared in the same manner as in Example 1, except that sorbitan monooleate and polyoxyethylene nonyl phenyl ether (1 plate instead of 2 plates, and 5 parts of pensalkonium chloride were added). was prepared.

The obtained film-type pack had a pH of 6.5.

Immediately after production, the viscosity of this pack agent increased dramatically, and the pack agent aggregated throughout and was not uniform. Further, as in Example 1, a practical test was conducted, and the result was that the coating did not spread well during coating, could not be applied uniformly, and could not be peeled off uniformly because a uniform film was not formed. At that time, I felt a strong stimulation. Comparative Example 3 A comparative example was prepared in the same manner as in Example 1, except that 5 parts of a betaine type amphoteric surfactant was added instead of sorbitan monooleate and polyoxyethylene nonyl phenyl ether (2.0. A pack agent was prepared.

The obtained film-type pack had a pH of 8.5, the viscosity increased immediately after production, and the product agglomerated throughout and was not uniform.
Further, as a result of carrying out a practical test in the same manner as in Example 1, it was found that the coating did not spread evenly during coating, was not uniformly coated, and did not form a uniform film, and therefore could not be peeled off uniformly. Comparative Example 4 Instead of a processed pigment in which the surface of titanium oxide was coated with octyldodecyl myristate, untreated titanium oxide 0 was used.
．． A comparative pack agent was prepared in the same manner as in Example 1, except that 5 parts were used.

The obtained film pack agent had a pH of 2.2, and the titanium oxide aggregated immediately after production and could not be uniformly dispersed. When the peeling time of this pack agent was examined, it was found that it could be peeled off uniformly in 11 minutes. Next, when the peeling stress was examined, it was found to be 3.2 hours, but uniform peeling could not be achieved. Furthermore, when stability was evaluated, the volume ratio of the cream phase was 1.0, but precipitation of titanium oxide was observed at the bottom.

In addition, this pack agent had a "rough" and uncomfortable feeling when applied, and could not be applied uniformly, and furthermore could not be peeled off uniformly.

As in Example 1, a storage test was carried out at 0 to 45°C, and as a result, some aggregation was found.

Comparative Example 5 A comparative pack was prepared in the same manner as in Example 1, except that sorbitan monooleate and polyoxyethylene nonyl phenyl ether (2 plates.0.) were not used, and 9.5 parts of water was used. A drug was prepared.

Immediately after production, the resulting pack agent had a pH of 7.6 and was not uniform throughout due to agglomeration.

Furthermore, the peeling time was long at 26 minutes, and the peeling stress was high at 18 minutes, making it evenly difficult to peel. I couldn't peel it off at once. The volume ratio of the cream phase was 0.80, and separation was observed, with the processed pigment settling at the bottom. When we conducted a practical test,
The adhesion to the skin was extremely strong and it could not be peeled off evenly.

Comparative Example 6 A comparative pack agent was prepared in the same manner as in Example 1, except that the free acid carboxyvinyl polymer was not used and 11.5 parts of water was used.

The obtained pack agent had a pH of 8.5 and a peeling time of 5 minutes. Next, when the peeling stress was examined, it was found to be 25 days, but it could not be peeled off uniformly. When the stability was evaluated, separation was observed at a cream phase volume ratio of 0.70, and the pigment was found to be precipitated at the bottom. Furthermore, this pack agent aggregated during application and did not spread uniformly, and did not form a uniform film, so it could not be peeled off uniformly.

Moreover, when the storage stability at 0 to 45 qo was examined in the same manner as in Example 1, it was found that the product aggregated completely at 45 qo for one month.
Comparative Example 7 The same procedure as in Example 1 was carried out, except that the processed pigment in which the surface of titanium oxide was coated with octyldodecyl myristate was not used, and 5 parts of water was used.

The pH of the obtained pack agent was 7.0, the peeling time was 12 minutes, and it could be peeled off uniformly. The peeling stress was stable at a cream phase volume ratio of 1, which allowed for uniform peeling in 3 days, but this pack agent became ``spotted'' when drying and the appearance of the film was non-uniform, which was not desirable for practical use. . Comparative Example 8 A processed pigment in which the surface of titanium oxide was coated with octyldodecyl myristate was not used, and instead, 0.01 part of octyldodecyl myristate and 0.01 part of untreated titanium oxide were used.
．． A comparative pack was prepared in the same manner as in Example 1, except that 48 parts were added individually.

The obtained pack agent had a pH of 7.2, and the titanium oxide aggregated immediately after production and could not be uniformly dispersed. When the peeling time of this pack agent was examined, it was 14 minutes. Next, when the peel stress was examined, it was found to be 3.6 mm, but uniform peeling could not be achieved. Furthermore, when stability was evaluated, the cream phase volume ratio was 1.0, but sedimentation of the pigment was observed in the lower part. In addition, this pack agent has a "feel" when applied.
It had a rough and uncomfortable feel and could not be applied uniformly, and the formed film could not be peeled off uniformly. 0 as in Example 1
A storage test at ~45q0 revealed partial aggregation.

Example 2 0.5 part of sodium cetyl sulfate was added to 99.9 parts of an unfilled polystyrene-butadiene copolymer latex emulsion (solid content concentration 55%) and stirred until uniform.

This mixture will be referred to as liquid A. Next, 3 parts of polyoxyethylene sorbitan monolaurate (20E.0.) 1 part of sorbitan sesquioleate, 5 parts of a 20% aqueous solution of polyvinyl alcohol (average degree of polymerization 1,300 to 1,500),
5 parts of polyethylene glycol, 0.1 part of citric acid, and a processed pigment in which the surface of zinc oxide is coated with dimethylpolysiloxane (abbreviated as DMPS) (the amount of DMPS adhered is 4.0% based on the weight of zinc oxide). 1 part and 5 parts of water were added and mixed. This mixture will be referred to as Solution B. Next, add A to the above B solution.
The liquid was gradually added while stirring, and the preparation was carried out in the same manner as in Example 1 to obtain a film-type pack agent of the present invention.

The pH of the obtained pack agent was 6.5, and the peeling time was 14 minutes.
The peeling stress was 2.8 hours, and the film could be peeled off uniformly. Furthermore, when stability was evaluated, the volume ratio of the cream phase was 1.0.
It was extremely stable. In addition, this pack spreads easily and can be applied easily and uniformly, forms a white uniform film in a short time, and can be easily and uniformly peeled off without irritating the skin layer.

Also, after peeling off, it gave a good moist feeling to the skin. As a result of storing this pack agent for 6 months within the range of 0 to 4520, the appearance was the same as immediately after production, but there was no discoloration, no separation,
No aggregation was observed.

Evaluation of stability showed that the product was stable at a cream phase volume ratio of 1.0. Furthermore, this pack spread evenly during application and could be easily and uniformly peeled off without irritating the skin. Although the moist feeling after peeling was less than that of the pack agent of Example 2, the overall feel was equally good. In addition, as a result of examining the storage stability for 6 months in the same manner as Example 2,
It was extremely good within the range of 0 to 45oo. Example
