Tripeptide-1, Hexapeptide-12, their metal salts and fatty acyl derivatives, and Palmitoyl Tetrapeptide-7 function primarily as skin conditioning agents, and Palmitoyl Tripeptide-1, Palmitoyl Hexapeptide-12, Tripeptide-1, Copper Tripeptide-1, and Palmitoyl Tetrapeptide-7 are also used in cosmetic products. Typical use concentrations of these ingredients are <10 ppm. The Panel noted that the low use concentrations and negative safety test data reviewed obviate any concerns relating to the safety of these ingredients in cosmetic products. Thus, the Panel concluded that these ingredients are safe in cosmetics in the present practices of use and concentration described in this safety assessment.
