Abstract
The invention relates to a cosmetic composition comprising: —from 2% to 20% by weight, relative to the total weight of the composition, of one or more fatty-chain alkoxysilanes of formula (I) below: R1Si(OR2)3 in which R1 represents a linear or branched alkyl or alkenyl group, comprising from 7 to 18 carbon atoms, and R2 represents a linear or branched alkyl group comprising from 1 to 6 carbon atoms, and —one or more non-siliceous fatty substances. The invention also relates to a cosmetic treatment process using the said composition, and to the use of the said composition for cosmetic treatment of the hair.

A cosmetic composition comprising:
- from about 2% to about 20% by weight, relative to the total weight of the composition, of at least one fatty-chain alkoxysilane of formula (I) below:
- R1Si(OR2)3 (I)
- in which R1 represents a linear or branched alkyl or alkenyl group, comprising from 7 to 18 carbon atoms, and R2 represents a linear or branched alkyl group comprising from 1 to 6 carbon atoms;
- and
- at least one non-siliceous fatty substance.
The composition according to claim 16, wherein the at least one non-siliceous fatty substance is chosen from liquid petroleum jelly, stearyl alcohol, cetyl alcohol.
A process for the cosmetic treatment of hair, said process comprising the steps of:
- applying to the hair an effective amount of a cosmetic composition comprising:
- from about 2% to about 20% by weight, relative to the total weight of the composition,
- of at least one fatty-chain alkoxysilane of formula (I) below:
- R1Si(OR2)3 (I)
- in which R1 represents a linear or branched alkyl or alkenyl group, comprising from 7 to 18 carbon atoms, and R2 represents a linear or branched alkyl group comprising from 1 to 6 carbon atoms;
- and
- at least one non-siliceous fatty substance;
- and
- optionally rinsing the hair after a leave-on time, in the presence or absence of heat.
