Is Stearamine Oxide natural?

Mostly. Stearyl chain is a natural fatty-alcohol/acid derivative; the dimethylamine-oxide head traces to ammonia and methanol, petrochemical reagents.

INCI nameStearamine Oxide
CAS2571-88-2
FormulaC20H43NO · 313.6 Da
FunctionAntistatic · Cleansing
FeedstockMade by converting stearic acid or alcohol, vegetable…

How we scored it

Octadecyl chain (C18H37, 253.5 Da, natural fatty) vs N,N-dimethylamine-oxide head (60 Da, ammonia+methanol-derived, petrochemical) / 313.6 Da ≈ 0.81.
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 converting stearic acid or alcohol, vegetable or tallow derived, to a fatty nitrile, then dimethylating and oxidising the nitrogen. The C18 chain is oleochemical; the amine-oxide head is petrochemical.

In plain English

A thickening and foam-stabilising surfactant made from a plant- or tallow-derived fatty chain joined to a small synthetic amine-oxide group. Used in shampoos, cleansers and shaving products.
