An object of the present invention is to provide novel dextrin fatty acid ester that is excellent in tackiness and useful as a base for cosmetics and the like. The novel dextrin fatty acid ester is prepared by esterification between dextrin and fatty acids, wherein the dextrin has an average degree of glucose polymerization of 3 to 150; the fatty acids comprise more than 50 mol % and 100 mol % or less, based on the total amount of the fatty acids, of one or more saturated branched fatty acids having 4 to 26 carbon atoms, and 0 mol % or more and less than 50 mol %, based on the total amount of the fatty acids, of one or more fatty acids selected from the group consisting of saturated linear fatty acids having 2 to 22 carbon atoms, unsaturated linear or branched fatty acids having 6 to 30 carbon atoms, and saturated or unsaturated cyclic fatty acids having 6 to 30 carbon atoms; and the degree of substitution by the fatty acids is 1.0 to 3.0 per glucose unit.

Dextrin fatty acid ester that does not cause gelation of liquid oil, and uses thereof

The present invention is a cosmetic composition comprising, component (A) and component (B), wherein, (A) is carboxylic acid ester of inulin and/or hydrolyzed inulin whose degree of substitution by acyl group is larger than 1, and (B) is cyclic silicone oil, and the present invention is the oily cosmetic compound further containing oleophilic component. More over, the present invention is the W/O type emulsified cosmetic composition prepared by further adding aqueous component and an emulsifier to above mentioned cosmetic compound. In the present invention, acyl group composing component (A) is desirable to be an acyl group of carbon number 14 to 22. Further, a part or all of acyl group composing component (A) is desirable to be palmiroyl group and/or stearoyl group. Furthermore, the above mentioned cosmetic composition can contain dextrin carboxylic acid ester whose degree of substitution by acyl group is 1.6 to 2.5. The cyclic silicone oil of component (B) is at least one selected from the group consisting of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane. The cosmetic composition of the present invention has light feel and is excellent in stability and fluidity.
