The present invention relates to cosmetic compositions that comprise: a) a safe and effective amount of a functionalized acid anhydride-based bonding agent having the structure (I) wherein X represents a cosmetic benefit agent that may or may not be attached via a chemical linker; and b) a cosmetically acceptable carrier for the bonding agent wherein the composition is administered topically to mammalian proteinaceous substrates and wherein the bonding agent reacts with a protein contained in the substrate such that the bonding agent, and thus the cosmetic benefit agent, is covalently attached to the substrate. The invention further relates to methods of using the compositions described above as well as various products that include the claimed compositions.
L'invention porte sur des compositions cosmétiques comportant: a) une quantité sûre et efficace d'un liant fonctionnalisé à base d'anhydride d'acide de structure (I) dans laquelle: X est un agent cosmétique pouvant ou non être fixé à un liant chimique; et (b) un support cosmétocompatible du liant. Une telle composition s'administre topiquement à des substrat protéiques de mammifères, et le liant réagit avec les protéines du substrat créant une liaison par covalence entre le substrat et le liant et donc avec l'agent cosmétique. L'invention porte en outre sur les procédés d'utilisation des susdites compositions et sur différents produits les contenant.
