Abstract
A cosmetic transparent gel preparation that has high levels of transparency and hardness and favorable usability, as well as a gelling agent that is ideal for use in the cosmetic transparent gel preparation. The cosmetic transparent gel preparation contains an esterification reaction product obtained by reacting glycerol with a dibasic acid of 18 to 28 carbon atoms and a fatty acid of 8 to 28 carbon atoms (excluding dibasic acids), 12-hydroxystearic acid, and an oil component. The gelling agent contains an esterification reaction product obtained by reacting glycerol with a dibasic acid of 18 to 28 carbon atoms and a fatty acid of 8 to 28 carbon atoms (excluding dibasic acids), and 12-hydroxystearic acid.
Claims15
A cosmetic transparent gel preparation, comprising
- an esterification reaction product obtained by reacting glycerol with a dibasic acid and a fatty acid,
- 12-hydroxystearic acid, and
- an oil component,
- wherein the dibasic acid is at least one dicarboxylic acid selected from the group consisting of octadecanedioic acid, nonadecanedioic acid and eicosanedioic acid,
- the fatty acid is at least one fatty acid selected from the group consisting of caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, ricinoleic acid, palmitoleic acid, isooctanoic acid, isononanoic acid, isopalmitic acid, isostearic acid, isoeicosanoic acid, cerotic acid, montanic acid and melissic acid,
- the oil component is at least one selected from the group consisting of liquid oils and fats, solid oils and fats, waxes, hydrocarbon oils, higher fatty acids, higher alcohols, synthetic ester oils, natural ester oils and silicone oils, and
- a mass ratio between the 12-hydroxystearic acid and the esterification reaction products is within a range of from 9:1 to 1:2.
A gelling agent, comprising
- an esterification reaction product obtained by reacting glycerol with a dibasic acid and a fatty acid, and
