How we scored it

Polyoxypropylene/polyoxyethylene glycerin ether succinate (contains natural glycerin fragment) salted with propylammonium dimethicone amine. Silicone content forces 0.00.
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

Manufactured by esterifying a polyoxypropylene/polyoxyethylene glycerin ether with succinic acid, then forming a propylammonium salt with an amino-functional dimethicone. The silicone content invokes this site's blanket 0.0 convention.

In plain English

A silicone-based ingredient used in hair care to reduce foaming and add conditioning. It combines silicone with petrochemical glycol and glycerin-ether components in a complex synthetic structure.
