Agent, useful e.g. to treat keratin fibers, especially human hair, comprises amphiphilic, cationic polymer comprising e.g. pyrrolidin-2-one unit, and amine unit, and film-forming cationic and/or solid cationic polymer in a carrier

摘要

Agent (A) comprises: at least one amphiphilic, cationic polymer, comprising at least one pyrrolidin-2-one unit (I), at least one azepan-2-one unit (II), at least one amine unit (III) and at least one quaternary ammonium unit (IV); and at least one additional film-forming cationic and/or solid cationic polymer in a carrier. Agent (A) comprises: at least one amphiphilic, cationic polymer, comprising at least one pyrrolidin-2-one unit of formula (I), at least one azepan-2-one unit of formula (II), and at least one amine unit of formula (-[-CH 2-C(R 1>)(-C(=O)-X 1>-A 1>-NR 3>-R 2>)-]-) (III) or at least one quaternary ammonium unit of formula (-[-CH 2-C(R 4>)(-C(=O)-X 2>-A 2>-N +>(R 5>)(R 6>)-R 7>)-]-) (IV); and at least one additional film-forming cationic and/or solid cationic polymer in a carrier. R 1>, R 4>H or CH 3; X 1>, X 2>O or NH; A 1>, A 2>ethan-1,2-diyl, propan-1,3-diyl or butan-1,4-diyl; R 2>, R 3>, R 5>, R 6>(1-4C)-alkyl; and R 7>(8-30C)-alkyl. Independent claims are included for a method for the treatment of keratin fibers, especially human hair, comprising: either foaming (A) using a delivery device and applying the resulting foam to the keratin fibers; or applying (A) using a delivery device as a spray onto the keratin fibers.
