How we scored it

Silicone (dimethicone) backbone = 0.0 by this site's convention; polypropylene glycol (12 units) side chain is also petrochemical. No natural fragment. 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

Made by reacting a dimethicone silicone fluid with polypropylene glycol, a petrochemical polyether, to add 12 propoxy units. Neither the silicone backbone nor the PPG chain has a natural-origin route.

In plain English

A silicone-based conditioning ingredient with a small petrochemical polypropylene glycol chain attached. Used in haircare and skincare products to add slip and a smooth, silky feel.
