Is Behenamidopropyl Ethyldimonium Ethosulfate natural?

Mostly. Behenic acid is oleochemical and the sulfate is mineral, but the aminopropyl-dimethylamine linker and both ethyl groups come from petrochemical DMAPA and diethyl sulfate (ethylene).

How we scored it

Natural: behenoyl C22H43O 323.6 + sulfate part OSO3 96.1 = 419.7. Petrochemical: NH-propyl-NMe2 (DMAPA) 101.2 + two ethyl groups 58.1 (diethyl sulfate) = 159.3. Total 578.9; 419.7/578.9 = 0.72.
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: behenic acid (hydrogenated high-erucic rapeseed oil) is amidated with DMAPA and the resulting tertiary amine is quaternised with diethyl sulfate. No bio-based alternative for DMAPA or diethyl sulfate is commercially significant.

In plain English

A conditioning agent used in hair and skin products to reduce static and make hair easier to comb. It is a quaternary ammonium compound made from behenic acid (from vegetable oil), a synthetic amine and diethyl sulfate, with ethyl sulfate as the counter-ion.
