Database/Antiplaque/Carboxylesterase
100% natural origin · ISO 16128

Is Carboxylesterase natural?

Yes. The enzyme is a protein from microbial fermentation or animal liver tissue, so every atom is amino-acid, natural-origin material.

INCI nameCarboxylesterase
CAS9016-18-6
FunctionAntiplaque
FeedstockDominant route: microbial fermentation (native or recombinant strains)…

How we scored it

Enzyme protein (EC 3.1.1.1) built wholly from amino acids; counted 1.0 under the protein and fermentation rules.
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

Dominant route: microbial fermentation (native or recombinant strains) followed by purification of the enzyme. Alternative: extraction from porcine liver.

In plain English

An enzyme that splits ester bonds, listed for use in oral care products against plaque. Enzymes are proteins made by microbial fermentation or extracted from animal tissue such as pig liver.

CosIng definition: Carboxylesterase is the enzyme that catalyzes the hydrolysis of carboxylic acids.
