How we scored it
31-amino-acid recombinant peptide built from standard amino acids by fermentation; no added 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
Produced by fermenting engineered E. coli expressing a gene based on human beta-endorphin, assembled from the 20 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 skin hold moisture and feel conditioned.
CosIng definition: sh-Oligopeptide-7 is a single chain recombinant human peptide, produced by fermentation in E. coli and contains 31 amino acids. The starting gene is synthesized to be identical to the human gene which codes for Beta Endorphin, and codes for a total of 267 amino acids which may contain disulfide bonds and/or sugar. The protein consists of the proper sequence of the 20 standard amino acids
