Title:
EMULSION COMPOSITION, AND SKIN TOPICAL AGENT AND COSMETIC CONTAINING SAID COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/033127
Kind Code:
A1
Abstract:
The purpose of the present is to provide an oil-in-water (O/W) emulsion composition which the user perceives as fresh at the time of application and as thick after application (after spreading out), and which can coexist with electrolytes in the composition. The present invention relates to: an oil-in-water (O/W) emulsion composition which contains an oil-base component in the emulsion particles, wherein the emulsion composition includes a component A and the oil-base component, the content of component A is 0.4-250 mass% with respect to the oil-base component, the emulsion composition contains substantially no surfactant, and in the case of containing surfactant, the content of said surfactant is less than or equal to 90 mass% with respect to component A and less than or equal to 3 mass% with respect to the oil-base component, and the content of the oil-base component in the emulsion composition is 1-65%; a skin topical agent and a cosmetic that contain said emulsion composition; and a production method of said emulsion composition. Component A: an acrylic acid ester (a) / compound (b) copolymer which comprises as constituent components an acrylic acid ester (a) that is represented in general formula [1] and a compound (b) that has, in the molecule, a polymerizable unsaturated group and a functional group that is selected from among a carboxyl group, a sulfo group and a phosphate group, wherein the ratio (mass ratio) of the acrylic acid ester (a) and the compound (b) is (a)/(b) = 6.0/94.0-30.0/70.0. General formula [1]: (in the formula, R1 represents a hydrogen atom or an alkyl group with 1-6 carbons, and m represents an integer 2-4.)
