Description

  The present invention relates to a vaginal cosmetic.

  Cosmetics for cocoons such as mascara are applied to cocoons to obtain cosmetic effects such as curling up and volume up of cocoons. Conventionally, these cocoon cosmetics are oil-in-water and water-in-oil types. Various types have been developed, such as those of an emulsified type and oily type.

  In addition to the above-mentioned cosmetic effect, there is a demand for a long-lasting cosmetic effect (hereinafter referred to as a “long rush effect”). To obtain this long lash effect, a cosmetic composition containing fibers is proposed. ing.

  In recent years, a vaginal cosmetic comprising a water-soluble polymer having spinnability, an α-olefin / vinylpyrrolidone copolymer, and a powder surface-treated with tridecafluorooctyltriethoxysilane. Further, those further containing fibers such as nylon and polyester have been proposed. And it is described that sufficient long rush effect can be acquired by using the cosmetics for wrinkles of such a composition (for example, refer patent document 1).

JP 2009-234978 A

  However, in the cosmetics for wrinkles described in the above-mentioned Patent Document 1, although the stringiness is imparted, the fibers arranged unevenly due to rubbing by hands or bangs, impact by blinking, etc. As a result, it was difficult to maintain the long rush effect for a long time.

  Therefore, the present invention has been made in view of the above-described problems, and provides a vaginal cosmetic that can obtain a long lash effect and is excellent in the sustainability of the liquid elongation effect even though the fiber is not blended. The purpose is to do.

  In order to achieve the above object, the cosmetic for vaginal skin of the present invention contains (A) a high degree of polymerization polyethylene glycol and (B) a water-swellable viscosity mineral, and the viscosity average molecular weight of the component (A) is 150,000. It is ˜3.8 million.

  According to the present invention, it is possible to exhibit an excellent long rush effect and to maintain a stable liquid elongation effect.

  Hereinafter, a preferred embodiment of the present invention will be described.

The vaginal cosmetic of the present invention is an oil-in-water vaginal cosmetic, and comprises the following components (A) and (B):
(A) High polymerization degree polyethylene glycol (B) Water-swellable clay mineral is contained, and the viscosity average molecular weight of the component (A) is 150,000 to 3,800,000.

<High polymerization degree polyethylene glycol>
The high polymerization degree polyethylene glycol is for imparting a liquid elongation effect to the bulk.

  In the present invention, the viscosity average molecular weight of the high-polymerization polyethylene glycol is 150,000 to 3.8 million as described above. This is because when the viscosity average molecular weight is less than 150,000, a sufficient liquid elongation effect cannot be obtained, and when it is larger than 3.8 million, the liquid elongation effect becomes too strong and the usability is lowered. . That is, an excellent long rush effect can be obtained by using a high polymerization degree polyethylene glycol having a viscosity average molecular weight of 150,000 to 3.8 million.

  In addition, it is preferable to use the high polymerization degree polyethylene glycol which has a viscosity average molecular weight of 500,000 to 1,500,000 from a viewpoint of obtaining a more excellent long lash effect. For the same reason, 0.1 to 10% by mass of polyethylene glycol with a high degree of polymerization is preferably blended with respect to the entire cosmetic for glazing, and more preferably 0.2 to 3% by weight.

  The “viscosity average molecular weight” referred to here can be obtained by measuring the viscosity of a polymer dilute solution. When the sample has a molecular weight distribution, the obtained molecular weight is the viscosity average molecular weight. The viscosity average molecular weight is larger than the number average molecular weight and smaller than the weight average molecular weight, but is closer to the weight average molecular weight (for example, “New Edition Polymer Analysis Handbook” edited by the Japan Analytical Chemical Society (published on January 12, 1995) )reference).

  The term “high degree of polymerization” as used herein refers to a case where the average molecular weight is 20,000 or more (for example, “Quasi-drug Raw Material Standard 2006” Yakuji Nippo Inc. (issued June 16, 2006). )reference).

  The “liquid elongation effect” here refers to an effect that allows the user (evaluation panelist) to feel the long rush effect when the cosmetics for glazing are applied to the candy.
