Claims18
A composition for permanently shaping keratin fibers comprising, in a cosmetically acceptable medium, at least one tetramethylguanidine, wherein the cosmetically acceptable medium and the concentration of the at least one tetramethylguanidine are chosen such that the at least one tetramethylguanidine is reactive with the cystines of the keratin fibers, via a beta-elimination reaction, to produce dehydroalanine and lead to the formation of lanthionine, to obtain keratin fibers having curls with a diameter ranging from 0.2 cm to 3 cm, in a permanent reshaping time of less than 60 minutes.
A kit for permanently shaping keratin fibers comprising at least two compartments, wherein at least one of the compartments comprises a composition comprising, in a cosmetically acceptable medium, at least one tetramethylguanidine, which is reactive with the cystines of keratin fibers, via a beta-elimination reaction to produce dehydroalanine and lead to the formation of lanthionine, to obtain keratin fibers having curls with a diameter ranging from 0.2 cm to 3 cm, in a permanent reshaping time of less than 60 minutes.
A process for permanently shaping keratin fibers comprising
- applying to the fibers a composition comprising, in a cosmetically acceptable medium, at least one tetramethylguanidine, wherein the cosmetically acceptable medium and the concentration of the at least one tetramethylguanidine are chosen such that the at least one tetramethylguanidine is reactive with the cystines of the keratin fibers, via a beta-elimination reaction to produce dehydroalanine and lead to the formation of lanthionine, to obtain keratin fibers having curls with a diameter ranging from 0.2 cm to 3 cm, in a permanent shaping time of less than 60 minutes.
An active agent for permanently shaping keratin fibers comprising at least one tetramethylguanidine reactive with the cystines of keratin fibers via a beta-elimination reaction producing dehydroalanine and leading to the formation of lanthionine.
