How we scored it
Decapeptide of Gly/Leu/Lys/Phe/Ser/Thr/Tyr; peptide bonds built from amino acids, coupling chemistry leaves no 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 recombinant/biosynthetic or solid-phase synthesis from ten natural amino acids matching the human enkephalin sequence. No significant alternative route.
In plain English
A lab-made chain of 10 amino acids designed to copy a natural skin peptide. It conditions hair and acts as an antioxidant, built from the same building blocks the body itself uses.
CosIng definition: sh-Decapeptide-7 is a single chain recombinant human peptide, produced synthetically to be identical to the protein, Enkephalin. It contains 10 amino acids consisting of glycine, leucine, lysine, phenylalanine, serine, threonine and tyrosine
