How we scored it
Recombinant peptide (up to 98 aa) from standard amino acids via fermentation; no petrochemical mass added.
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 engineered E. coli expressing a gene based on human CXCL10, assembled from standard amino acids. No alternative commercial route.
In plain English
A lab-made peptide modeled on a natural skin-signalling protein, produced by fermenting engineered bacteria, used to help condition skin.
CosIng definition: sh-Oligopeptide-11 is a single chain recombinant human peptide, produced by fermentation in E. coli. The starting gene is synthesized to be identical to the human gene which codes for CXCL10. It contains a maximum of 98 amino acids which may contain disulfide bonds and/or sugar. The protein consists of the proper sequence of the 20 standard amino acids
