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). Further, as a shaving aid not containing fatty acid soap as a main base, there are non-foaming gel-like shaving agent compositions (Patent Documents 1 and 2).

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 mainly uses higher fatty acid salts such as palmitic acid and stearic acid to improve foam retention, and is foamed physically by foaming of propellant to sustain and retain shape. 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 taken out of the container more than necessary. 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.
On the other hand, the aerosol type post-foaming gel cream is a gel base that is a shaving aid mixed with a liquefied gas having a relatively 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 inventors have (A) an anionic surfactant (excluding higher fatty acid salts), (B) white powder and / or polymer emulsion, (C) polysaccharide polymer, (D) carboxyvinyl polymer and It has been found that the above problems can be achieved by using a combination of acrylic acid / alkyl methacrylate copolymer and water.

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) an anionic surfactant (excluding higher fatty acid salts), (B) white powder and / or polymer emulsion, (C) polysaccharide polymer, (D) carboxy. Contains vinyl polymer and / or acrylic acid / alkyl methacrylate copolymer and water 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 anionic surfactant (A) is an important component for facilitating washing off the shaving agent composition and having a good feeling of use due to its surface active action. is there. 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 containing the carboxyvinyl polymer and / or the acrylic acid / alkyl methacrylate copolymer (D), the shaving agent composition of the present invention is less likely 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 period of time, and the distinction between the shaved trace and the unshaved place is clear.

  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. In order to obtain the desired adhesion, it is necessary to contain a certain amount of the polysaccharide polymer (C). However, if it is excessively contained, it becomes sticky 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) has less stickiness 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 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 anionic surfactant (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.
