Is Polyquaternium-70 natural?

Mostly. Stearyl and dilinoleic (dimer) fatty-acid portions are natural; the EO/PO chains, adipic acid linker and methylsulfate quat cap are petrochemical.

FunctionHair Conditioning

How we scored it

Stearylamine (natural fatty amine) + dilinoleic acid (natural dimer fatty acid) are the dominant-mass fragments; ethoxylation/propoxylation, adipic acid and methylsulfate quat cap are petrochemical (minor mass); estimated ≈0.6 (exact EO/PO level undisclosed).
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

Built from oleochemical stearylamine and dimer (dilinoleic) fatty acid, extended with petrochemical ethylene/propylene oxide and adipic acid, then quaternized with dimethyl sulfate. Exact ethoxylation level is not disclosed, so this is an estimate.

In plain English

A hair-conditioning polymer built from a fatty stearylamine base reacted with synthetic ethylene/propylene oxide chains and combined with natural dimer fatty acid, then quaternized.

CosIng definition: Polyquaternium-70 is the polymeric quaternary ammonium salt consisting of an ethoxylated, propoxylated stearyl amine condensed with adipic acid and dilinoleic acid and quaternized with dimethyl sulfate
