Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated SR-(METHIONYL SH-POLYPEPTIDE-131 DIPEPTIDE-19 HEXAPEPTIDE-40). However, the broader category of protein hydrolysates, which contain bioactive peptides, is recognized as Generally Recognized As Safe (GRAS) by the FDA. CIR has previously deemed other related peptides, such as Acetyl Hexapeptide-8 Amide, safe for cosmetic use at concentrations up to 0.005%.
