Topical composition comprising an activated, trans-structured cosmetic bonding agent

摘要

The present invention relates to cosmetic compositions that comprise a safe and effective amount of a bonding agent comprising trans structurewherein X represents a cosmetic benefit agent, L represents an optional chemical linker between X and a remainder of the bonding agent; and R represents an activating electron withdrawing group; and 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.
