Description

  The present invention relates to an oil-in-water cosmetic for cosmetics containing spherical silicone particles having microprojections over the entire surface of the particle, an alkali-thickened polymer emulsion, and polyvinyl alcohol. For the effect of separating one by one without attachment (hereinafter sometimes referred to as “separate effect”), and for the makeup effect that makes the eyes stand out, the effect that makes wrinkles appear thick (hereinafter referred to as “volume effect”) In addition, it is excellent in the effect that can be applied uniformly and neatly when applying the cosmetics for wrinkles to the wrinkle multiple times (hereinafter sometimes referred to as “easy to apply”), and when removing makeup, The present invention relates to an oil-in-water vaginal cosmetic that is excellent in makeup removal properties, such that the cosmetic coating does not peel off finely and can be peeled off from the wrinkles.

  The cosmetic for wrinkles is a cosmetic having a cosmetic effect such as curling the wrinkles or making the wrinkles thick and long to make the eyes stand out. Such vaginal cosmetics are applied to wrinkles, and need to have adhesion that prevents the cosmetic coating from peeling off due to physical movement, water resistance, oil resistance, and durability that do not bleed due to tears or sebum. . For this reason, we devised various dosage forms such as oil-based type with continuous phase oil and no water, aqueous type with water continuous phase and no oil, oil-in-water type, water-in-oil type, etc. Cosmetics for candy are being developed.

  The oil-type vaginal cosmetics are excellent in terms of makeup effect and durability, and the water-based type has the characteristics of being excellent in applicability and makeup removal. And emulsifying types such as oil-in-water type and water-in-oil type are expected as a dosage form that combines the good points of both the oily type and aqueous type, and can be given various functions. Has been made. Specifically, technologies to increase the amount of wax, resin and film-forming agent added to emulsified vaginal cosmetics in order to impart water resistance, oil resistance and shape retention ability like oil-based molds, A technique (for example, see Patent Document 1) in which a microdispersion of wax is blended to impart force has been studied.

  However, the vaginal cosmetics improved in water resistance, oil resistance and durability by the above-described technology makes it difficult to remove the cosmetic film, and has a high solvent property such as dissolving the cosmetic film components. There is a need for a special removal agent. However, since such a removal agent has high solvent properties, it has a drawback that a large burden is placed on the eyes such as squinting.

  For this reason, there has been a study on cosmetics for salmon that can easily remove the cosmetic coating without using a solvent-specific remover for cosmetics for salmon. The deterioration of water resistance and oil resistance was inevitable. Further, studies have also been made on vaginal cosmetics (see, for example, Patent Document 2) that can be removed with warm water by using a hydrophobic film-forming polymer and a specific ionic surfactant in combination.

  It has been said that cosmetics for vaginal use require techniques for makeup, but recently, consumers with a shallow makeup calendar often use it, so that it is not necessary to use techniques for makeup. Cosmetics for vases with improved separation effects, volume-imparting effects, and ease of overlaying have been developed.

  Specifically, a technique for blending a spherical silicone-based resin powder into an oil-in-water type salmon cosmetic (see, for example, Patent Document 3), an oil-type salmon cosmetic containing oil as a continuous phase, and a confetti-shaped silicone type Techniques for blending resin powders (for example, see Patent Document 4) have been studied.

Japanese Patent No. 29898929 JP 2003-137732 A Japanese Patent Laid-Open No. 11-12132 JP 2009-149525 A

  However, by using a hydrophobic film-forming polymer in combination with a specific ionic surfactant, vaginal cosmetics that can be removed by warm water can increase the water resistance and makeup sustainability to some extent. When dropping, it was necessary to prepare warm water, and there was inconvenience that it was not removed by face washing using tap water directly.

  In addition, when washing the face using conventional remover or tap water directly, the result of removing the makeup film while dissolving the cosmetic film, the ingredients of the eyelid cosmetic dissolved around the eyes remain, Dissatisfaction that it was darkened and problems such as being unable to see if makeup removal was completed were pointed out. Furthermore, it is difficult to apply a cosmetic film with the technology of blending silicone resin powder, and when a consumer with a shallow makeup calendar cannot use it, a satisfactory makeup effect cannot be obtained in terms of finish. was there.

  For this reason, it is excellent in the separation effect, the volume imparting effect, and the ease of overlaying, and when the makeup is removed, the makeup coating does not peel off finely and can be peeled together from the wrinkles Development of an oil-in-water cosmetic for cosmetics that has excellent makeup removal properties has been desired.

  In such a situation, as a result of intensive studies to solve the above problems, the present inventors have obtained an oil-in-water cosmetic for cosmetics that combines an alkali-thickened polymer emulsion and polyvinyl alcohol. It has been found that the cosmetic coating does not peel off finely, but can be peeled off from the wrinkles and is excellent in makeup removal, and further, spherical silicone particles having fine protrusions over the entire surface of the particles. It has been found that an oil-in-water type cosmetic for cosmetics excellent in separation effect, volume effect and ease of overlaying can be obtained by blending.

  The component (a) spherical silicone particles having fine protrusions over the entire surface of the particles used in the present invention are particles having fine protrusions on the spherical silicone particle surface. Moreover, the particle | grains of a component (a) become a shape which has a microprotrusion over the whole surface instead of a part of spherical silicone particle surface, and is a particle | grain like a so-called konpeito. Furthermore, the microprotrusions in the particles of component (a) are chemically bonded, and unlike microparticles formed by mixing and adsorbing spherical silicone particles and different particles, the microprotrusions are different. Are particles that are not easily missing.

  The silicone particles of component (a) are organosilsesquioxane particles, and organotrialkoxysilanes such as methyltrimethoxysilane and methyltriethoxysilane described in Japanese Patent No. 3455562 are used with an alkali catalyst. It is manufactured by a method of hydrolysis / condensation.
