100% natural origin · ISO 16128

Is Nonapeptide-7 natural?

Yes. All residues are proteinogenic amino acids from fermentation or protein hydrolysate; coupling agents and protecting groups leave no mass in the product.

FunctionSkin Conditioning
FeedstockDominant route is chemical peptide synthesis from fermentation-derived…

How we scored it

Sum of residues (Ala, Arg, Cys, Leu, Phe, Pro, Ser, Thr) is 100% natural origin; no acyl or acetyl cap in the INCI name (end groups not stated). 100% / 100% = 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

Dominant route is chemical peptide synthesis from fermentation-derived amino acids, with reagents and protecting groups leaving no mass. Recombinant or enzymatic assembly is a less common alternative with identical atoms.

In plain English

A short chain of nine amino acids made by laboratory synthesis, used in skin-care products to condition the skin. It is built from alanine, arginine, cysteine, leucine, phenylalanine, proline, serine and threonine, the same amino acids found in natural proteins.

CosIng definition: Nonapeptide-7 is a synthetic peptide consisting of alanine, arginine, cysteine, leucine, phenylalanine, proline, serine and threonine
