TOPICAL COMPOSITION COMPRISING AN ALDEHYDE OR KETONE-BASED COSMETIC BONDING AGENT

摘要

The present invention relates to cosmetic compositions that comprise; a) a safe and effective amount of a bonding agent selected from the group consisting of aldehydes and ketones having the structure (I) wherein X represents a cosmetic benefit agent that may or may not be attached via a chemical linker and R represents hydrogen, straight or branched alkyls, substituted or unsubstituted aryls, and combinations thereof; and b) a cosmetically acceptable carrier for the bonding agent wherein the compositio n 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 attach ed 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.
