Is Volcanic Ash natural?

Q: Is Volcanic Ash natural?

Volcanic Ash has a Natural Origin Index (NOI) of 1.00 (scale 0–1) per ISO 16128. An amorphous mineral silicate mined directly from volcanic deposits, inherently natural origin. An NOI of 1.00 means 100% of its molecular mass is traceable to a natural, renewable source.

Yes. An amorphous mineral silicate mined directly from volcanic deposits, inherently natural origin.

INCI nameVolcanic Ash

FunctionAbrasive · Absorbent

FeedstockMined from natural volcanic lava/ash deposits and processed…

How we scored it

Inorganic mineral silicate from lava deposits, = 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

Mined from natural volcanic lava/ash deposits and processed only by grinding and purification. Composition is an amorphous inorganic silicate.

In plain English

A fine mineral powder formed from lava, used in cosmetics to gently exfoliate, absorb oil, and add bulk to formulas.

CosIng definition: Volcanic Ash is an amorphous, inorganic silicate obtained from lava deposits
