How we scored it

Lauryl (natural) plus methicone + 18 EO/18 PO (petrochemical); this site's convention scores all silicones 0.0 regardless of the lauryl fragment.
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 reacting a lauryl methicone silicone intermediate with ethylene oxide and propylene oxide. The lauryl portion may be coconut-derived, but the silicone backbone and alkoxylation are petrochemical.

In plain English

A silicone-based skin-conditioning ingredient combining a coconut-derived lauryl group with a silicone backbone and synthetic ethylene/propylene oxide chains. It is made by chemically reacting these building blocks together.

CosIng definition: Lauryl PEG/PPG-18/18 Methicone is an alkoxylated derivative of Lauryl Methicone containing an average of 18 moles of ethylene oxide and 18 moles of propylene oxide
