| abstract |
The invention relates to modified polypeptides of the KAP family (Keratin associated protein), and their use in compositions intended for the care, treatment, reinforcement and / or repair of keratinous substrates, in particular keratinous fibers. In particular, the invention relates to salified polypeptides or polypeptides modified by covalent bonding of the KAP family, adapted to a better formulation in cosmetic compositions.n n n The invention also relates to methods for preparing said modified polypeptides. It also relates to cosmetic compositions containing said modified polypeptides as well as to cosmetic processes for the care, reinforcement and / or repair of keratin substrates using said compositions. |
