How we scored it
Enzyme protein built only from amino acids (animal-tissue extract or recombinant fermentation); no synthetic fragments = 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
Traditionally extracted from bovine or ovine testes and purified; recombinant forms are produced in cultured cells or microbes. Both routes give a natural-origin protein.
In plain English
An enzyme that breaks down hyaluronic acid, listed for skin conditioning. It is a protein, obtained from animal tissue or made by microbial or cell-culture fermentation.
CosIng definition: Hyaluronidase is the enzyme which catalyses hydrolysis of the glycosidic linkage of hyaluronic acid
