Abstract
Abstract A cosmetic composition comprising a long-chain alkyltrimethylol is disclosed. The alkyltrimethylol is represented by the formula (I): <CHEM> wherein R is a linear or branched, saturated or unsaturated alkyl group having 8-22 carbon atoms. The composition is applied to varios types of cosmetic and exhibits superior extendibility when applied, imparts a non-sticky, fresh feeling upon use, and provides an excellent moisture-retaining effect.
