Is Boron Nitride natural?

Mostly not. Boron traces to mineral borax/boric acid (natural); nitrogen is introduced via ammonia or urea made from natural gas (petrochemical per this site's method).

How we scored it

BN (24.82 Da) = B 10.81 Da (natural, from borax/boric acid) + N 14.01 Da (petrochemical, natural-gas ammonia); 10.81/24.82 = 0.44.
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

Manufactured by reacting a boron source (boric acid or borax, mineral-derived) with a nitrogen source (ammonia or urea, made from natural gas) at high temperature. This is a fully synthetic ceramic material with no natural mined equivalent in commercial use.

In plain English

A fine, silky powder used to add slip and bulk to powders and makeup. It is manufactured by reacting a boron mineral source with an ammonia or urea nitrogen source at high temperature.
