About
An E. coli-produced 211-amino-acid fusion peptide with rainbow trout and human-mimicking domains, positioned for antioxidant and multi-functional skin/hair conditioning.
This recombinant fusion peptide joins rainbow trout s-Oligopeptide-1 with sh-Polypeptide-7 and Hexapeptide-40 in a single 211-residue chain expressed in E. coli. sh-Polypeptide-7 is commonly associated with keratinocyte growth factor (KGF/FGF-7) mimetics in CosIng. The absence of restriction entries in EU Annexes indicates this ingredient has not been subject to specific SCCS safety concerns. Standard Good Manufacturing Practice (GMP) controls for recombinant cosmetic ingredients include residual protein, DNA, and endotoxin testing.
