Description

The present invention relates to an oil-soluble UV absorber solid at 25 ° C., R ¹ SiO _1.5 units and R ² ₃ SiO _0.5 units (wherein R ¹ and R ² are substituted or unsubstituted monovalent carbonizations) The present invention relates to an emulsified cosmetic containing a silicone resin comprising a hydrogen group), a volatile oil and water, and more particularly to an emulsified cosmetic having a non-sticky usability.

  Conventionally, UV absorbers, UV scattering agents, and the like are blended in cosmetics having UV protection effects. Cinnamic acid type, benzoic acid ester type, salicylic acid type, benzophenone type, dibenzoylmethane type UV absorber, triazine type UV absorber, etc. are blended as UV absorbers, and the properties are liquid to solid It is various. Among these, triazine-based ultraviolet absorbers are attracting attention because they have a high molar extinction coefficient and can absorb ultraviolet rays having a wider wavelength (see, for example, Patent Document 1). Triazine-based UV absorbers are attractive as a material that protects against UV rays, but on the other hand, because the properties are solid, they are difficult to dissolve in other oily components and absorb other UV rays in terms of usability such as stickiness. It is inferior to the agent. Various studies have been made so far in order to improve the stickiness of ultraviolet absorbers, and techniques for blending oily components such as silicone oil, powder, resin for forming a film, alanine and the like are known. For example, a combination of a UV absorber and a methylsiloxane network polymer (for example, see Patent Document 2) or a combination of a specific organopolysiloxane, a water-repellent resin powder, and a UV absorber (for example, , Patent Document 3), a combination of an ultraviolet absorber, an ultraviolet scattering agent and alanine (for example, see Patent Document 4) has been studied.

On the other hand, there is a technique in which a silicone resin composed of R ¹ SiO _1.5 units and R ² ₃ SiO _0.5 units is combined with fine metal oxides or metal hydroxides and used in cosmetics (see, for example, Patent Document 5). ).

  As described in Patent Document 2, a compound containing an ultraviolet absorber and a methylsiloxane network polymer improves the ease of use and the refreshing effect, but the effect of suppressing stickiness of the ultraviolet absorber is not sufficient. It was. In addition, the combination of specific organopolysiloxane, water-repellent resin powder and UV absorber as in Patent Document 3 suppresses stickiness against liquid oil-soluble UV absorber and water-soluble UV absorber. Although it is effective, the stickiness-suppressing effect was not sufficient for solid oil-soluble UV absorbers. Moreover, although what combined the ultraviolet absorber and alanine like patent document 4 has the effect of recovering the damage of the skin by an ultraviolet-ray, it cannot be said that the inhibitory effect of stickiness is enough. The technique of Patent Document 5 is a technique for reducing the adhesion of sand and the like to the skin by using a silicone resin together with the fine particle powder, and the effect of suppressing the stickiness of the solid oil-soluble ultraviolet absorber is completely different. There was no disclosure.
