Is Zinc Lactate natural? NOI 1.00

Q: Is Zinc Lactate natural?

Zinc Lactate has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. Zinc salt of lactic acid; zinc is a mineral ion and lactic acid is a fermentation product, both natural. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

How we scored it

Zinc is a natural mineral ion; lactate is a fermentation product. Both fragments natural. 100% natural.

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

Made by neutralising fermentation-derived lactic acid with a zinc source. Both the zinc ion and the lactate are natural-origin under ISO 16128.

In plain English

A mineral salt combining zinc with lactic acid, which is made by fermentation. Used in deodorants for its odour-controlling, deodorant properties.

Structure
