How we scored it

Silicone ether with PEG-7 isostearate side chain; site-convention 0.00 for silicones applies regardless of the isostearate/PEG substituent → 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

Made by etherifying a hydroxypropyl dimethicone with PEG-7 monoisostearate (isostearic acid ethoxylated with ethylene oxide). The silicone backbone and PEG chain are both petrochemical-linked; this site's convention scores it 0.0.

In plain English

A silicone-based conditioning ingredient used in hair and skin products to add slip and shine. It's a synthetic silicone modified with a fatty-acid/PEG side chain.
