Abstract
The hair treatment composition for increasing the formability and luster of hair contains from 0.01 to 10 percent by weight of a copolymer formed from at least one ethylenic unsaturated monomer of the formula (I): EQU CH.sub.2.dbd.CR.sup.1 R.sup.2 (I), wherein R.sup.1 is A--(CH.sub.2 CH.sub.2 O).sub.x --R.sup.3 or COOH group and A is C(.dbd.O)O, C(.dbd.O)NH or CH.sub.2 O, x is a number from 1 to 100, R.sup.3 is a C.sub.8 - to C.sub.30 -alkyl group, R.sup.2 is H, a C.sub.1 - to C.sub.30 -alkyl group or a CH.sub.2 --R.sup.1 group, with the proviso that at least one of the groups, R.sup.1 and R.sup.2, contain the A--(CH.sub.2 CH.sub.2 O).sub.x --R.sup.3 group; and from at least one ethylenic unsaturated monomer of the formula (II): EQU CH.sub.2.dbd.CR.sup.4 COOR.sup.5 (II), wherein R.sup.4 and R.sup.5 are, independently of each other, H or an alkyl group with 1 to 30 carbon atoms; from 0.01 to 50 percent by weight of a polyethylene glycol with a molecular weight over 500 g/mol and from 0.01 to 20 percent by weight of a nonionic surfactant having an HLB-value under 20.
