Abstract
A method for blending a compound is effective in preventing or improving skin aging with a composition in a chemically stable manner. The method can increase the uniform dispersibility of the compound in the composition. A compound represented by the following general formula (1), and/or an isomer thereof is dispersed in an oiling agent having 0 to 2 hydroxy groups to prepare an oil-based composition, thereby suppressing the decomposition of the compound. The composition further contains a powder, a solid fat and/or a semi-solid fat, thereby suppressing the sedimentation of the compound in the composition over time.
Claims10
An oil-based composition, comprising a compound represented by the following general formula (1), an isomer thereof and/or a pharmacologically acceptable salt thereof and an oiling agent having 0 to 2 hydroxy groups,
- wherein R1 represents a linear or branched C1-4 alkyl group substituted with a carboxyl group, or a linear or branched C1-4 alkyl group substituted with a carboxylic acid ester group having a C1-4 alkyl chain, and R2 and R3 each independently represent a linear or branched C1-4 alkyl group.
