Description

  The present invention relates to a shaving agent composition used when shaving body hair such as wrinkles and unwanted hair with a razor.

  A shaving aid is used when shaving a sword or body hair with a razor. There are many shaving aids based on fatty acid soaps, such as general soaps, shaving soaps, shaving creams, aerosol-type shaving foams, and post-foaming gel creams (non-patent literature). 1). Moreover, there exists a gel-like shaving agent composition (patent document 1, patent document 2) etc. as a shaving adjuvant which does not use fatty acid soap as the main base.

However, the soap needs to be bubbled by itself during use. Also, since the soap has poor foam sustainability and shape retention, the foam disappears or drips down during shaving, and it is unclear whether the soap solution remains on the skin. For this reason, it is difficult to understand the shave marks on the skin and where the soap solution needs to be applied.
Shaving soap is mainly used for business purposes, and produces a foam that is thicker and more durable than ordinary soap. However, since the shaving soap is a solid substance such as a powder, it is necessary to add water to the foam during use. Moreover, since the hygroscopic property is strong in a solid state, there is a problem that it is easily solidified during storage.
Aerosol-type shaving foam uses long-chain fatty acids such as palmitic acid and stearic acid to improve foaming, and it is sustained and shape-retaining by physically foaming by foaming of the propellant. A good foam is formed. Therefore, the foam is difficult to disappear from the skin while shaving. However, the shaving foam tends to be wasted because it is excessively removed from the container. In addition, since the foam formed after jetting is mostly gas and has a small amount of water, it is necessary to wet the skin and wrinkles with water in advance to soften the foam.

The non-foamable gel-like shaving agent composition represented by Patent Documents 1 and 2 contains a large amount of moisture, so that the wrinkles are soft and the razor slips are good. The distinction of where the agent remains is unclear. Moreover, the problem remains in the washability.
The aerosol-type post-foaming gel cream is a gel base that is a shaving aid mixed with a liquefied gas having a high boiling point and filled into a container. When the gel base is sprayed from the container onto the skin, the liquefied gas is vaporized and foamed. However, the post-foaming gel cream, like the aerosol-type shaving foam, has a small amount of water because most of the foam is gas, and it is necessary to use a pressure-resistant aerosol container.

  In addition, Patent Document 3 describes a creamy pre-shave cosmetic containing an insoluble powder having a specific particle size. This pre-shave cosmetic is formulated so as to improve the shaving feeling of the heel by blending insoluble powder and to prevent dripping due to blending of insoluble powder. However, it has a drawback that it is difficult to wash off due to the difficulty of dripping. In addition, a means for making the shaving mark easy to understand is not particularly considered.

Japanese Patent Laid-Open No. 9-132516 Japanese Patent Laid-Open No. 10-87454 JP 2003-34627 A Nanzan-do, New Cosmetic Science, 2nd edition, 392-396 pages

  The present invention does not require foaming during use, the whiteness of the agent applied on the skin lasts for a long time, is rich in water, can sufficiently soften wrinkles and skin, and is easy to wash away. Offer things.

The present inventors have (A) a higher fatty acid salt of 1 to 20% by mass, (B) a total of 0.2 to 0.9% by mass of a titanium oxide and / or styrene / acrylic resin copolymer emulsion (of the polymer emulsion). In this case, it is a solid content conversion amount), (C) 0.1-2% by mass of polysaccharide polymer, (D) 0.1-1 of carboxyvinyl polymer and / or acrylic acid / alkyl methacrylate copolymer. It has been found that the above problems can be achieved by a gel-like or paste-like non-foamable water-based shaving agent composition in which water% and water are combined.

The shaving agent composition of the present invention can be applied to the skin as it is without foaming because it has a thick white color and excellent shape retention, and it is difficult to sag. Therefore, even after a long time has elapsed after application on the skin, the whiteness of the applied part is maintained, and it is easy to see where the shaving marks and the shaving agent composition remain on the skin.
Moreover, since the shaving agent composition of the present invention contains abundant moisture and has shape retention, it supplies a sufficient amount of moisture to body hair such as wrinkles and skin without dripping from the place where it is applied. As a result, body hair such as wrinkles and skin can be sufficiently softened. Furthermore, the shaving agent composition of the present invention has good slidability. Therefore, the shaving taste is very good and it is difficult to cause razor loss.
Furthermore, the shaving agent composition of the present invention can be easily washed away.
As described above, when the shaving agent composition of the present invention is an aqueous composition in which components (A) to (D) are combined, excellent usability and usability can be obtained.

  The shaving agent composition of the present invention comprises (A) a higher fatty acid salt, (B) a white powder and / or polymer emulsion, (C) a polysaccharide polymer, (D) a carboxyvinyl polymer and / or acrylic acid / methacrylic acid. An alkyl copolymer and water are contained as essential components. The reason why the components (A) to (D) are combined is as follows.

  First, as a basic function of each of the above components, the higher fatty acid salt (A) is an important component for facilitating washing of the shaving agent composition and having a good feeling of use due to its surface activity. . The higher fatty acid salt (A) also has an effect of softening wrinkles by the action of the base moiety. The white powder and / or polymer emulsion (B) is a component for imparting whiteness to the appearance of the shaving agent composition. The polysaccharide polymer (C) is a component for imparting the slidability of a razor to the shaving agent composition. The carboxyvinyl polymer and / or the acrylic acid / alkyl methacrylate copolymer (D) has a good shape retaining property and forms a water-containing gel that continuously releases water, thereby improving the shaving agent composition. It is an important component for increasing the viscosity or shape retention and also enabling the continuous supply of moisture to the wrinkles and skin. Since this component (D) has little stickiness to the skin, the feeling of use is also good. Water is not only a medium for the shaving agent composition, but also an important component for softening wrinkles and skin.

  In the present invention, a white powder and / or polymer emulsion (B) is used in combination with a carboxyvinyl polymer and / or an acrylic acid / alkyl methacrylate copolymer (D) to form a gel or paste having a thick whiteness. A shaped shaving agent composition can be prepared. As a result, the shaving agent composition of the present invention does not lather at the time of use, and the whiteness of the shaving agent composition is conspicuous even if it is applied to the skin as it is, and the application part can be clearly seen.

Moreover, since the viscosity or shape retention property is improved by mix | blending the carboxy vinyl polymer and / or the acrylic acid / alkyl methacrylate copolymer (D), the shaving agent composition of the present invention is difficult to sag from the skin. . As a result, when the shaving agent composition of the present invention is applied to the skin, the white of the applied portion remains without disappearing for a long time.
Therefore, the portion where the shaving agent composition of the present invention is applied is well noticeable due to the whiteness of the composition even after a long time has passed, and the shaving marks and unshaved places are not lost.

  The shaving agent composition of the present invention can be applied on the skin for a long time by the action of carboxyvinyl polymer and / or acrylic acid / alkyl methacrylate copolymer (D) which can form a hydrated gel having good shape retention when applied to the skin. The remaining water is continuously supplied to the eyelids and skin. As a result, wrinkles and skin become sufficiently soft. In addition, the skin coated with the shaving agent composition of the present invention has good razor slipperiness due to the action of the polysaccharide polymer (C). Moreover, since the polysaccharide polymer (C) has excellent adhesion to the skin, the slidability of the razor is maintained even when the same place is shaved twice or more. Therefore, the shaving agent composition of the present invention can shave well and is less likely to cause razor loss such as turning over of the stratum corneum of the skin or congestion.

  In addition, since the polysaccharide polymer (C) has good salt resistance, even when the shaving agent composition of the present invention is applied to unwashed skin in which a large amount of salt derived from sweat or the like is present, Adhesion does not decrease. However, in order to obtain the desired adhesion, it is necessary to add a relatively large amount, and if it is added excessively, stickiness is generated, and the feeling of use of the shaving agent composition becomes unfavorable. On the other hand, the carboxyvinyl polymer and / or the acrylic acid / alkyl methacrylate copolymer (D) is less sticky to the skin and can give a preferable feeling of use. However, component (D) has insufficient salt resistance, and when applied to skin with a high salt content, adhesion to the skin decreases. The shaving agent composition of the present invention has the disadvantages of using the polysaccharide-based polymer (C) and the carboxyvinyl polymer and / or acrylic acid / alkyl methacrylate copolymer (D) in combination. The point is relieved and excellent shape retention is obtained even when applied to salty skin.

Furthermore, since the shaving agent composition of this invention contains the said higher fatty acid salt (A), it can wash away from the skin after shaving easily. Further, since the carboxyvinyl polymer and / or the acrylic acid / alkyl methacrylate copolymer (D) is used, there is little stickiness of the skin after washing.
In the present invention, the interaction of the components (A) to (D) as described above is expected, and these components are used in combination.

Specifically, commercially available products such as Carbopol 940, Carbopol 941, Carbopol 980, Carbopol 981 (above, Noveon Inc.), AQPEC HV-501E (Sumitomo Seika Co., Ltd.) can be used. . Of these, carbopol 940 is preferable from the viewpoints of stability and usability.

  The acrylic acid / alkyl methacrylate copolymer of component (D) is a copolymer of acrylic acid and alkyl methacrylate (preferably having 8 to 30 carbon atoms in the alkyl group). For example, commercially available products such as Pemlen TR-1, Pemlen TR-2, Carbopol EDT2020, Carbopol 1382 (Noveon Inc.) can be used.

Easy to wash off and less likely to lose razor. Further, the shaving agent composition of the present invention can be used as it is without foaming because the composition itself has a thick whiteness. Therefore, the shaving agent composition has good usability and usability. Moreover, since a pressure resistant container having an aerosol injection mechanism is not required, there is an effect that the cost for the container can be reduced.
In addition, the shaving agent composition of the present invention can be used as it is without foaming after being taken out of the container, but in order to obtain a thicker white, it is stirred with a brush or the like at the time of use or rubbed by hand. It can be used by lathering. Moreover, when the shaving agent composition is a concentrated type formulation, the composition may be used after it is easily extended by adding water in the palm or the like.

Further, although not clearly shown in the table, Examples 1 to 3 and 5 containing (E) oil agent gave a moist and preferable feeling to the skin after washing.

On the other hand, since Comparative Example 1 does not contain the component (B), whiteness is not imparted to the shaving agent, and “easiness to see the agent on the skin” and “ease of understanding the shaving trace” are insufficient. It became a thing. Moreover, since it did not contain the component (A), the “rinseability” was also lacking.
Since Comparative Example 2 did not contain the component (B), “easiness to see the agent on the skin” and “ease of understanding the shaved trace” were insufficient. Furthermore, since it did not contain the component (C), “razor sliding” was insufficient.
Since Comparative Example 3 did not contain the component (A), it was lacking in “washability”. Moreover, compared with the case where a component (A) and (B) were contained, "easiness of seeing of an agent on skin" and "easiness to understand a shaving trace" were also inadequate.
