Is Quaternium-90 Montmorillonite natural?

Mostly. Montmorillonite is a mineral clay and the long alkyl chains of the quaternary ammonium come from animal or vegetable fat, while its nitrogen and short substituents derive from petrochemical amines.

How we scored it

Organoclay assumed 65% montmorillonite (mineral) + 35% quaternary ammonium cation; of the cation about 75% is fat-derived alkyl chain, 25% petrochemical N, methyl and benzyl-type groups. 0.65 + 0.35 x 0.75 = 0.91.
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 exchanges the sodium ions of purified montmorillonite for a fatty quaternary ammonium cation (Quaternium-90) in water. The exact structure and loading of Quaternium-90 are not given in the data, so the value is an estimate.

In plain English

A clay thickener and emulsifier treated with a fatty quaternary ammonium compound so that it disperses in oils and solvents. The clay is mineral; the treatment is partly fat-derived and partly synthetic.

CosIng definition: Quaternium-90 Montmorillonite is the product obtained by the reaction of Quaternium-90 and Montmorillonite.
