Our take
Is PEG-8 Dimethicone a Good Ingredient?
Rated Good because it reliably improves slip and emulsion stability while remaining generally low-irritation and lightweight, thanks to its water-dispersible silicone structure. It works as a texture tool rather than a treatment ingredient, which is where the rating settles.
