How we scored it
Peptide from Tyr,Ala,Gly,Phe,Leu,Asp; 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 from six fermentation-derived amino acids joined by peptide bonds. No petrochemical alternative exists.
In plain English
A lab-assembled chain of six natural amino acids used to condition hair and skin. The amino acids are fermentation-derived and simply linked together.
CosIng definition: Hexapeptide-18 is the synthetic peptide consisting of tyrosine, alanine, glycine, phenylalanine, leucine and aspartic acid
