Abstract
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.

A polymer for use in hair-care product comprising a copolymer comprising (a) a unit of a hydrophilic ethylenically unsaturated monomer in a quantity of 15 to 99.9% by weight, said ethylenically unsaturated monomer being selected from the group consisting of anoinic and cationic monomers;
- (b) a unit of an ethylenically unsaturated monomer having a polysiloxane group in a quantity of 0.1 to 85% by weight;
- and (c) a unit of hydrophobic ethylenically unsaturated monomer in a quantity of 0 to 84.9% by weight, said hydrophobic ethylenically unsaturated monomer is a monomer selected from a group consisting of saturated and unsaturated alkyl (meth)acrylate having 1 to 24 carbon atoms in the alkyl;
- hydrophobic (meth)acrylates and their derivatives selected from a group consisting of butoxyethyl (meth)acrylate, benzyl (meth)acrylate, tetrahydrofufuryl (meth) acrylate, ethyleneglycol di(meth)acrylate, 1,3-butyleneglycol di(meth)acrylate, and diacetoneacrylamide;
- aromatic unsaturated monomers;
- and vinyl esters.
A polymer for use in hair-care products comprising a copolymer comprising (a) a unit of a hydrophilic ethylenically unsaturated monomer in a quantity of 15 to 99.9% by weight, said ethylenically unsaturated monomer being selected from the group consisting of anionic and cationic monomers;
- (b) a unit of an ethylenically unsaturated monomer having a polysiloxane group in a quantity of 0.1 to 85% by weight, said ethylenically unsaturated monomer having a polysiloxane group being formed by copolymerizing said monomer in the form of (meth)acrylic acid and reacting the copolymerized monomer with a polysiloxane having a terminal epoxy group;
- and (c) a unit of hydrophobic ethylenically unsaturated monomer in a quantity of 0 to 84.9% by weight.
