Abstract
The present invention relates to leave-on compositions for personal care comprising trimethylsilylalkylsilsesquioxanes, particularly trimethylsilyl-n-octylsilsesquioxanes (Caprylyl Trimethicones). Said trimethylsilylalkylsilsesquioxanes are especially useful in formulating emulsions.
Claims17
Leave-on composition for personal care comprising from 0.1 to 60% by weight of at least one trimethylsilylalkyl-silsesquioxane of formula (1)
- Me3SiO—[Si(R)(Me3SiO)O]x—SiMe3 (1)
- wherein Me is methyl, and R is a straight or branched alkyl group having from 6 to 18 carbon atoms and x is a number from 1 to 10, wherein the leave-on composition is an emulsion.
Process for increasing the gloss and sheen of hair, wherein said process comprises applying an effective amount of a leave-on composition comprising from 0.1 to 60% by weight of at least one trimethylsilylalkylsilsesquioxane of formula (1)
- Me3SiO—[Si(R)(Me3SiO)O]x—SiMe3 (1)
- wherein Me is methyl, and R is a straight or branched alkyl group having from 6 to 18 carbon atoms and x is a number from 1 to 10, to said hair wherein the leave-on composition is an emulsion.
Process for increasing the emolliency of the skin, wherein said process comprises applying an effective amount of a leave-on composition comprising from 0.1 to 60% by weight of at least one trimethylsilylalkylsilsesquioxane of formula (1)
- Me3SiO—[Si(R)(Me3SiO)O]x—SiMe3 (1),
- wherein Me is methyl, and R is a straight or branched alkyl group having from 6 to 18 carbon atoms and x is a number from 1 to 10, to said skin, wherein the leave-on composition is an emulsion.
Process for increasing the water repellency of the skin, wherein said process comprises applying an effective amount of a leave-on composition comprising from 0.1 to 60% by weight of at least one trimethylsilylalkylsilsesquioxane of formula (1)
- Me3SiO—[Si(R)(Me3SiO)O]x—SiMe3 (1),
- wherein Me is methyl, and R is a straight or branched alkyl group having from 6 to 18 carbon atoms and x is a number from 1 to 10, to said skin, wherein the leave-on composition is an emulsion.
