How we scored it

Antimicrobial enzyme (protein), typically from egg white or fermentation; amino-acid-based = 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 hen egg white, or increasingly produced by microbial fermentation. Both routes yield a natural-origin protein.

In plain English

A natural enzyme, traditionally sourced from egg white and now also made by fermentation, used to help condition skin.

CosIng definition: N-Acetylmuramide glycanohydrolase; Muramidase
