PROBLEM TO BE SOLVED: To provide an oil-in-water emulsified cosmetic which is excellent in long-term stability without requiring the use of a surfactant, and has a good feeling in use and finish. SOLUTION: The molecular weight represented by the following general formula (1) is 5 An oil-in-water type emulsified cosmetic is prepared by forming an emulsion with 100,000 to 3,000,000 alkyl-modified carboxyvinyl polymer as an emulsifier and other cosmetic ingredients, and blending glucomannan or the like with the emulsion. (However, in the general formula (1), R 1 is a hydrogen atom or an alkyl group having 10 to 30 carbon atoms, and n, n ′, m and m ′ are n + n ′ + m + m ′ = An arbitrary number such as 40 to 100 is shown, and l is an arbitrary number such that the molecular weight falls within a predetermined range. ) |
