How we scored it

Oleoyl C18H33O (265) + SO3Na (103) natural = 368; N-methyl-ethylene bridge C3H7N (57, methylamine/ethylene-oxide route, petrochemical) -> 368/425.6 = 0.87.
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 condensing oleic acid, from vegetable oil, with N-methyltaurine, industrially produced from ethylene oxide (or isethionic acid) and methylamine, both petrochemical.

In plain English

A mild, foaming cleansing surfactant made from a vegetable-oil fatty acid joined to a small sulfonate molecule. Used in gentle shampoos and body washes.
