Cosmetic raw material cosmetic product and method for manufacturing cosmetic products

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:
• where Y is a radical-polymerizable organic group, R1 is an aryl group or an alkyl group having 1 to 10 carbon atoms, and X1 is a silylalkyl group which when i=1 has the formula:
• where R1 is the same as defined above, R2 is an alkylene group with 2 to 10 carbon atoms, R3 is an alkyl group having 1 to 10 carbon atoms, Xi+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 ai is an integer from 0 to 3;
• with the proviso that when i=10,Xi+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:
• where R4 is a hydrogen atom or an alkyl group, R5 is an alkylene group having 1 to 10 carbon atoms;
• and
• a group having the formula:
• where R6 is a hydrogen atom or an alkyl group, R7 is an alkyl group with 1 to 10 carbon atoms, R8 is an alkylene group having 1 to 10 carbon atoms, b is an integer from 0 to 4, and c is 0 or 1.
