How we scored it

Dimethicone backbone scored 0.0 by this site's convention; PEG/PPG side and end chains are also petrochemical (ethylene oxide, propylene oxide) = 0.0
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

A silicone polymer with polyethylene/polypropylene glycol chains grafted on and end-capping it, made from petrochemical ethylene oxide and propylene oxide. No part of the molecule is treated as natural-origin.

In plain English

A silicone ingredient modified with water-loving side chains so it can blend oil and water together. It helps creams and lotions feel silky and spread evenly.
