How we scored it
Catalase is a protein enzyme; no formula given so no data conflict. Proteins/enzymes from living organisms or fermentation are natural-origin, fraction = 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
Catalase used in cosmetics is typically produced by fermenting selected microorganisms and purifying the enzyme from the broth. It also occurs naturally in plants, animals, and fungi.
In plain English
An enzyme, a natural protein, that conditions hair and skin. It occurs in nearly all living things and for cosmetics is usually produced by fermenting microorganisms rather than extracted from plants or animals.
CosIng definition: Catalase is an enzyme found in animals, plants, bacteria and fungi.
