Problems solved by technology

[0006] However, in order to achieve both tactility and water resistance, it is limited to (diphenyl dimethicone / vinyl diphenyl dimethicone / silsesquioxane) cross-linked polymers and high-polymerization dimethicone Combination of methicones, if dimethicone with a high degree of polymerization is mixed with sunscreen cosmetics, there is a problem that the width of the tactile sensation is limited due to heavy texture

Abstract

The present invention is a sunscreen cosmetic characterized by comprising the following components (A) to (E): (A) an ultraviolet-ray-blocking agent; (B) a volatile oily material; (C) cetyl dimethicone copolyol; (D) an (acrylate / stearyl acrylate / dimethicone methacrylate) copolymer; and (E) an organic modified clay mineral. The purpose of the present invention is to provide a sunscreen cosmetic having an extremely high water-proof effect, excellent emulsion stability and an excellent sensation upon application.

Description

technical field [0001] The present invention relates to sunscreen cosmetics. More specifically, it relates to a sunscreen cosmetic having an extremely high water-resistance effect and excellent emulsion stability and feel upon use. Background technique [0002] Among emulsified sunscreen cosmetics, sunscreen cosmetics having a high water-resistance effect and excellent emulsification stability and feel upon use are required. [0003] For example, Patent Document 1 discloses an emulsified sunscreen cosmetic that has excellent water repellency (water repellency), low re-emulsibility when in contact with water, good makeup durability, and excellent touch, emulsion stability, and safety. The sunscreen cosmetics described in Patent Document 1 do not use existing surfactants, but emulsify oily substances with acrylic acid-alkyl methacrylate copolymers, and use a water-resistant film-forming agent in combination to provide a sunscreen with excellent water resistance. Emulsified s...
