How we scored it

Peptide/protein built from standard amino acids via fermentation = 1.0, independent of chain length (170 residues).
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 genetically engineered E. coli expressing a human vasoactive-intestinal-peptide-identical sequence built from standard amino acids. No petrochemical alternative route is used commercially.

In plain English

A lab-made copy of a human nerve-signalling peptide (VIP), produced by fermenting engineered bacteria. Used to condition skin and hair.

CosIng definition: sh-Polypeptide-71 is a single chain synthetic human peptide, produced by fermentation in E. coli. The starting gene is a synthesized copy of the human gene which codes for Vasoactive Intestinal Peptide used as such or adapted to the production host. It contains a maximum of 170 amino acids which may contain disulfide bonds and/or glycosylation. The protein consists of the proper sequence of the 20 standard amino acids.
