Abstract
A cosmetic and a topical skin preparation comprising a higher alcohol-modified silicone (A) with the following general formula (1) wherein R1 is, e.g., an alkyl group; P is a monovalent organic group that contains the Si—O bond or is a long-chain monovalent hydrocarbyl group; at least one Q is a higher alcohol modifying group (—(C10-C30)-OH); and (m1+m2+m3) is a number in the range from 0 to 55 and most favorably (m1+m2+m3) is 1.
Claims9
A cosmetic and topical skin preparation comprising a higher alcohol-modified silicone (A) with general formula (1-1-1),
- wherein each R1 is independently a C1-10 alkyl group, C6-10 aryl group, or a —OH group;
- Ra is a branched or straight-chain C10-30 alkylene group or an arylene group;
- and
- at least one C10-30 higher alcohol (B) at from 5 to 1000 mass parts per 100 mass parts of the higher alcohol-modified silicone (A).
A method of producing a cosmetic and topical skin preparation comprising:
- a step of heating 100 mass parts of at least one higher alcohol-modified silicone (A) with general formula (1-1-1),
- wherein each R1 is independently a C1-10 alkyl group, C6-10 aryl group, or a —OH group;
- Ra is a branched or straight-chain C10-30 alkylene group or an arylene group,
- and 10 to 1000 mass parts of at least one C10-30 higher alcohol (B), at from 50° C. to 150° C.
