TOPICAL COMPOSITION

WIPO Patent Application WO/2020/085134

A1

The present invention is a topical composition which contains structural units (a) derived from a monofunctional ethylenic unsaturated monomer (A), structural units (b) derived from a monofunctional ethylenic unsaturated monomer (B), and structural units (c) derived from a monofunctional ethylenic unsaturated monomer (C) as essential structural units, and contains a copolymer (D) free from structural units derived from ethylenic unsaturated monomers having a functionality of 2 or higher. The monomer (A) is free from phosphorus atoms and silicon atoms in the molecule. The monomer (B) has an HLB of 0.3-5.2. The molar ratio of the structural units (a) is 2-55 mol%, the molar ratio of the structural units (b) is 0.01-10 mol%, and the molar ratio of the structural units (c) is 43-97.99 mol%. The ratio (Mw/Mn) of the weight average molecular weight (Mw) to the number average molecular weight (Mn) of the copolymer (D) is 2.0-7.0. The copolymer (D) has a cation charge density of 1.2-1.6 meq/g.
