How we scored it

Peptide of 9 amino acids (Ala,Gly,Gln,Pro,Ser), all fermentation-derived; peptide bonds lose only water, no petrochemical mass.
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 fermentation-derived amino acids via solid-phase peptide synthesis. No alternative petrochemical route.

In plain English

A synthetic chain of nine amino acids (alanine, glycine, glutamine, proline, serine) used to condition hair and skin. The amino acids are fermentation-derived building blocks joined together in a lab.

CosIng definition: Nonapeptide-12 is the synthetic peptide consisting of alanine, glycine, glutamine, proline and serine.
