Abstract (en)

[origin: DE19751395A1] Use of specific cationic polymers in hair care formulations to protect keratin from heat-damage and help treat and prevent split-ends. Cationic polymers comprising repeating units of formula: R<1>-(C-(CH2))n-COO(CH2)mN<+>R<2>R<3>R<4> . X<-> (I) are used in formulations to prevent and treat split ends and to protect keratinic fibres from damage by heat. (where: R<1> = H or CH3; R<2>-R<4> = 1-4C (hydroxy)alkyl, or 2-4C alkenyl; m = 1-4; X = an anion; and n = natural integer). An Independent claim is also included for an aqueous composition for treating keratinic fibres containing: (a) 0.2-5 wt.% of cationic polymer(s) having repeating units of formula (I); and (b) 0.1-5 wt.% vitamins and/or vitamin precursors as agents for reducing and repairing split ends.
