How we scored it
Protein enzyme; amino-acid residues are fermentation/protein-derived, natural origin. 1.0.
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
Commercially produced by microbial fermentation (Streptomyces species); historically also sourced from animal tissue. No petrochemical route.
In plain English
An enzyme, usually produced by fermentation, used here as a skin-conditioning ingredient.
CosIng definition: Transglutaminase is the enzyme that catalyses the formation of an amide bond between glutamine and lysine residues
