How we scored it
Peptide from Ala,Glu,Gly,Leu,Phe,Tyr; condensation water lost only → 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Synthesised by joining six amino acids, fermentation/hydrolysate commodities, via peptide bonds. No petrochemical route exists.
In plain English
A lab-made chain of six natural amino acids used to condition skin. The amino acids come from fermentation and are linked together to form the peptide.
CosIng definition: Hexapeptide-17 is a synthetic peptide consisting of alanine, glutamic acid, glycine, leucine, phenylalanine, and tyrosine; Alanine, synthetic hexapeptide with glutamic acid, glycine, leucine, phenylalanine and tyrosine
