Abstract

Methods for styling, in particular for straightening, keratin fibers, in particular human hair, in which (i) a styling agent comprising carbocisteine and/or a salt thereof is applied to the keratin fibers and left there, (ii) the fibers, after a leave-in time, —are not rinsed, —are optionally dried, (iii) the fibers are mechanically deformed from exposure to heat, significantly minimize the negative consequences of styling and reduce in particular electrostatic charging and hydrophilization of the hair.

First claim

What is claimed is:

1 . A method for styling keratin fibers, in which
(i) applying a styling agent comprising carbocisteine and/or a salt thereof to the keratin fibers and left thereon for a leave-in time, (ii) the fibers, after the leave-in time,
are not rinsed,
are optionally dried,
(iii) the fibers are mechanically deformed from exposure to heat.

2 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight, 0.01 to 10 wt % carbocisteine.

3 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight, 0.1 to 7.5 wt %, carbocisteine.

4 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight, 0.25 to 5 wt %, carbocisteine.

5 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight, 0.5 to 2.5 wt % carbocisteine.

6 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight, 0.55 to 2 wt % carbocisteine.

7 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight 30 to 95 wt % water.

8 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight 40 to 92.5 wt % water.

9 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight 50 to 90 wt % water.

10 . The method according to claim 1 , wherein the styling agent comprises, based on its total weight, 0.15 to 7.5 wt % quaternary ammonium compound(s) selected from the group
i) tetraalkylammonium halides; ii) esterquats; iii) quaternary imidazolines of formula (Tkat2)

 in which the radicals R independently of one another each represent a saturated or unsaturated, linear or branched hydrocarbon radical having a chain length of 8 to 30 carbon atoms and A represents a physiologically acceptable anion;
iv) amines and/or cationized amines;
