Is sh-Polypeptide-7 natural?

Yes. Assembled purely from fermentation-derived amino acids in engineered E. coli; glycosylation adds no synthetic mass.

How we scored it

Recombinant protein from the 20 standard amino acids via fermentation; no petrochemical mass in the final chain.
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

Produced by fermenting E. coli engineered with a synthetic copy of the human growth hormone gene; amino acids are the sole feedstock. No alternative commercial route exists.

In plain English

A lab-made protein produced by fermenting engineered bacteria carrying a copy of the human growth hormone gene. Used in skincare for its sebum-regulating and skin-protecting properties.

CosIng definition: sh-Polypeptide-7 is a single chain recombinant human peptide, produced by fermentation in E. coli. The starting gene is a synthesized copy of the human gene which codes for Somatotropin the synthetically produced Human Growth Hormone, used as such or adapted to the production host. It contains a maximum of 217 amino acids which may contain disulfide bonds and/or glycosylation. The protein consists of the proper sequence of the 20 standard amino acids.
