About
A 228-amino-acid E. coli fusion peptide combining rainbow trout oligopeptide with human-mimicking domains for broad-spectrum antioxidant and conditioning benefits.
This recombinant fusion peptide is assembled from s-Rainbow Trout Oligopeptide-1, sh-Polypeptide-85, and Hexapeptide-40, expressed in E. coli. sh-Polypeptide-85 sequences correspond to various growth-factor mimetics or cytokine-like peptides registered in CosIng. The 228-residue chain (~26 kDa) has limited dermal penetration potential. The ingredient is not subject to EU restrictions; standard cosmetic safety assessment under Regulation (EC) No 1223/2009 applies.
