| titleOfInvention | Cationic group-containing copolymer and thickener |
| abstract | A cationic group-containing copolymer is provided which possesses excellent thixotropy and exhibits high adsorbadility to the skin, hair, etc. and, when incorporated as a thickener in cosmetic articles, manifests a very satisfactory tactile sensation. The cationic group-containing copolymer is characterized in that the viscosity at 25 DEG C of the aqueous solution prepared by incorporating the copolymer in deionized water at a concentration of 0.5 wt.% is in the range of 0.3-20 Pa.sec. At a shear rate of 1 sec<SP>-1</SP> and in the range of 0.01-5 Pa.sec, at a shear rate of 10 sec<SP>-1</SP> and the viscosity at a shear rate of 1 sec<SP>-1</SP> is higher than the viscosity at a shear rate of 10 sec<SP>-1</SP>. This cationic group-containing copolymer is obtained by particularly using a cationic group-containing vinyl monomer, a hydrophilic nonionic group-containing vinyl monomer such as N,N-dimethyl (meth)acrylamide or N,N-diethyl (meth)acrylamide, and a cross-linking vinyl monomer containing at least two vinyl groups in the molecular unit thereof as essential component monomers and radically polymerizing the essential component monomers. A thickener made of the copolymer is also disclosed. |
