PROBLEM TO BE SOLVED: To provide a cationic thickener for use in cosmetics or aromatics with extremely excellent thickening performance compared to the prior art.SOLUTION: The cationic thickener is obtained by polymerizing a monomer composition which contains at least an amine-containing (meth)acrylic monomer represented by the general formula (1), a (meth)acryloyl group-containing monomer and a crosslinkable vinyl monomer. (R1 is H or a methyl group R2 and R3 are each independently H, a methyl group, an ethyl group or a t-butyl group A is O or -NH- group, and B is a linear or branched C1-4 alkylene group)COPYRIGHT: (C)2016,JPO&INPIT【課題】化粧品や芳香剤に用いる、従来のものよりも増粘性能が非常に優れるカチオン性増粘剤の提供。【解決手段】少なくとも、一般式(1)で表されるアミン含有(メタ)アクリル系モノマー、及び(メタ)アクリロイル基含有モノマー、及び架橋性ビニルモノマーを含有するモノマー組成物を重合して得られるカチオン性増粘剤。(R1はH又はメチル基;R2及びR3は各々独立してH、メチル基、エチル基又はt-ブチル基;AはOまたは-NH-基、Bは直鎖状又は分岐鎖状の炭素数1~4のアルキレン基)【選択図】なし
