Shaving composition for the skin based on polyorgano-siloxanes containing an acyloxyalkyl group and process for use

Claim 1

Composition intended for shaving of the skin, characterized in that it contains, in a cosmetically acceptable medium including a foaming agent, a polyorganosiloxane containing an acyloxyalkyl group, selected 531 (i) linear compounds corresponding to the following average formula (I): ##STR15## in which: the radicals R, which may be identical or different, are selected from methyl, phenyl, OCOR" and hydroxyl radicals; only one of the radicals R per silicon atom can be OH; the radicals R', which may be identical or different, are selected from methyl and phenyl radicals; at least 60 mol % of all the radicals R and R' is methyl; R 1 represents a divalent linear or branched alkylene group of the hydrocarbon type containing from 2 to 18 carbon atoms; R" is a C 8 -C 20 alkenyl or alkyl radical; r is a number between 1 and 120 inclusive; p is a number between 1 and 30; and q is equal to 0 or is a number not exceeding 0.5 p, the sum p+q being between 1 and 30; it being possible for the compounds of formula (I) optionally to contain ##STR16## groups, present in proportions not exceeding 15% of the sum p+q+r; and (ii) cyclic compounds represented by the following average formula (II): ##STR17## in which: R', R" and R 1 have the same meaning as in the formula (I); s is a number between 0 and 20; t is a number between 1 and 20; and u is equal to 0 or is equal to a number not exceeding 0.5 t, the sum t+u being between 1 and 20; the sum s+t+u being not less than 3.
