Abstract:
The present invention relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one fatty-chain polylysine. The composition of the invention enables to improve the surface state of keratin fibres. The invention also relates to methods for producing fatty-chain polylysines, as well as new compounds.
Abstract:
The present invention relates to the use of a cosmetic composition containing compounds derived from polyguanidines or physiologically acceptable salts thereof for the protection of keratin fibres during permanent-shaping treatments or hair-straightening operations. The invention also relates to a cosmetic treatment process for permanently shaping or straightening keratin fibres, such that it consists in applying to these fibres a composition containing a compound derived from polyguanidines.
Abstract:
The present invention relates to novel compounds corresponding to formula (I) below: The invention also relates to the process for manufacturing them, to their use as pigments and to a cosmetic composition comprising them.
