Abstract

Disclosed is an oil-in-water emulsion sunscreen cosmetic composition which has improved ultraviolet blocking capability by containing a large amount of an ultraviolet absorbent, while having excellent emulsion stability and good usability. Specifically disclosed is an oil-in-water emulsion sunscreen cosmetic composition which is characterized by containing (A) 1-7.5% by mass of octyl methoxycinnamate, (B) 0.5-4% by mass of t-butyl methoxybenzoyl methane and / or 2-hydroxy-4-methoxybenzophenone, (C) 0.5-3% by mass of a polyoxyethylene-polyoxyalkylene alkyl ether block polymer having a specific structure and (D) not less than 10% by mass of a nonpolar oil relative to the total amount of the oil component. The oil-in-water emulsion sunscreen cosmetic composition is also characterized by having an average emulsion particle diameter of not more than 700 nm.

Description

technical field [0001] The present invention relates to an oil-in-water emulsified composition. More specifically, it relates to a combination of a specific ultraviolet absorber, a selected surfactant of a specific structure, and a non-polar oil for compounding to obtain a large amount of stable compounded ultraviolet absorbing It is an oil-in-water emulsified sunscreen cosmetic with excellent UV protection ability and good usability. Background technique [0002] The purpose of sunscreen cosmetics is to block the ultraviolet rays in the sun's rays and protect the skin from the adverse effects of ultraviolet rays. As its base, emulsified type, lotion type, oil type, etc. can be mentioned. Among them, the oil-in-water type emulsified type has a moist feeling in use, and can be formulated from low SPF to high SPF products, so it is widely used (Non-Patent Document 1). [0003] On the other hand, there are oil-soluble substances and water-soluble substances in the ultraviolet...
