| abstract |
The invention relates to a hair treatment agent containing - based in each case on the weight thereof -0.1 to 20 weight percent of at least one silicone comprising groups of the formula (I), in which n represents values from 1 to 1000, A represents a group (G), in which R1 represents H or CH 3 , and R represents a straight-chain or branched alkyl radical having 8 to 24 c-atoms, and a is an integer from 1 to 20; 0.1 to 20 weight percent of at least one copolymer comprising monomer units of the formulas (V) and (VI), in which R2 represents for H or CH 3 and X represents H, an alkali metal cation, or a straight-chain or branched alkyl radical having 1 to 24 c-atoms; 0.5 to 5 weight percent of 2-phenylbenzimidazole-5-sulfonic acid. The hair treatment agent according to the invention has an improved protective effect against UV radiation and has an improving effect on hair treated therewith with regard to combability, gloss, elasticity, brittleness, and maximum tensile strength. |
