Abstract:
A method of treating skin or hair comprising applying to skin or hair in need thereof, a cosmetic product comprising a solution or dispersion of a polymer in a liquid selected from the group consisting of silicone oils, organic oils, alcohols and water, the polymer having a carbosiloxane dendrimer in its side molecular chain comprising a polymer obtained by polymerizing:(A) 0 to 99.9 parts by weight of a vinyl monomer; and(B) 100 to 0.1 parts by weight of a carbosiloxane dendrimer which contains an organic group of the formula: ##STR16##where Y is a radical-polymerizable organic group, R.sup.1 is an aryl group or an alkyl group having 1 to 10 carbon atoms, and X.sup.1 is a silylalkyl group which when i=1 has the formula: ##STR17##where R.sup.1 is the same as defined above, R.sup.2 is an alkylene group with 2 to 10 carbon atoms, R.sup.3 is an alkyl group having 1 to 10 carbon atoms, X.sup.i+1 is a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an aryl group, or said silylalkyl group; i is an integer from 1 to 10 which represents the generation of said silylalkyl group, and a.sup.i is an integer from 0 to 3; with the proviso that when i=10,X.sup.i+1 cannot be said silylalkyl group; wherein said radical-polymerizable organic group Y contained in component (B) is selected from the group consisting of groups having the formulae: ##STR18##where R.sup.4 is a hydrogen atom or an alkyl group, R.sup.5 is an alkylene group having 1 to 10 carbon atoms; anda group having the formula: ##STR19##where R.sup.6 is a hydrogen atom or an alkyl group, R.sup.7 is an alkyl group with 1 to 10 carbon atoms, R.sup.8 is an alkylene group having 1 to 10 carbon atoms, b is an integer from 0 to 4, and c is 0 or 1.
