Cosmetic and topical skin preparation comprising higher alcohol-modified silicone
View Patent ↗A cosmetic and a topical skin preparation comprising a higher alcohol-modified silicone (A) with the following general formula (1) wherein R 1 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.
1. A cosmetic and topical skin preparation comprising a higher alcohol-modified silicone (A) with general formula (1-1-1),
wherein each R 1 is independently a C 1-10 alkyl group, C 6-10 aryl group, or a —OH group; R a is a branched or straight-chain C 10-30 alkylene group or an arylene group; and
at least one C 10-30 higher alcohol (B) at from 5 to 1000 mass parts per 100 mass parts of the higher alcohol-modified silicone (A).
2. The cosmetic and topical skin preparation according to claim 1 further containing water (C) and a surfactant (D), wherein the preparation forms a gel structure.
3. The cosmetic and topical skin preparation according to claim 1 , wherein the preparation is an oil-in-water emulsion cosmetic.
4. The cosmetic and topical skin preparation according to claim 1 further containing a silicone resin (E).
5. The cosmetic and topical skin preparation according to claim 1 further containing a silicone elastomer (F).
6. 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 R 1 is independently a C 1-10 alkyl group, C 6-10 aryl group, or a —OH group; R a is a branched or straight-chain C 10-30 alkylene group or an arylene group,
and 10 to 1000 mass parts of at least one C 10-30 higher alcohol (B), at from 50° C. to 150° C.
7. The method according to claim 6 , further comprising:
a step of mixing the at least one higher alcohol-modified silicone (A) and the at least one C 10-30 higher alcohol (B) before the step of heating.
8. The cosmetic and topical skin preparation according to claim 4 wherein the silicone resin (E) is an organopolysiloxane having a network structure.
9. The cosmetic and topical skin preparation according to claim 5 wherein the silicone elastomer (F) is a liquid silicone elastomer.
