A polymer suitable for use in hair care products comprising a copolymer comprising

Hair-care products containing copolymers formed from unsaturated

A hair cosmetic composition containing a graft copolymer or an alternating block copolymer, each of which comprises a first unit containing a polysiloxane group and a second unit containing a polymer of unsaturated monomers is provided. The first and second units are linked by sulfide linkage. The hair cosmetic composition provides hair with softness, luster, combing smoothness, styling ease, enhanced volume, and has good hairstyle retainability and damage-restoring characteristics.

Hair cosmetic compositions comprising sulfide linked polysiloxanes

A polymer suitable for use in hair care products comprising a copolymer comprising (a) a unit of a hydrophilic ethylenically unsaturated monomer such as dimethylaminoethyl methacrylate in a quantity of 15 to 99.9% by weight; (b) a unit of an ethylenically unsaturated monomer having a polysiloxane group such as: ##STR1## in a quantity of 0.1 to 85% by weight; and (c) a unit of an optional hydrophobic unsaturated monomer such as lauryl methacrylate in a quantity of 0 to 84.9% by weight.

Polymer for hair-care products

A hair setting gel composition comprising (A) from 0.2 to 5% by weight of a partially of completely neutralized salt of a crosslinked carboxyvinyl polymer, (B) from 0.5 to 10% by weight of an amphoteric resin, and (C) from 85 to 99.5% by weight of a solvent mainly comprising water and/or a lower alcohol, with the total of the components (A), (B) and (C) being 100% by weight. The gel composition is excellent in transparency and hair setting performance.
