Science
Mechanism of Action
This ingredient utilizes its dimethicone component to create a subtle, vapor-permeable film on the skin, contributing to a smooth, silky texture and a delicate gloss. This occlusive layer can temporarily diminish the appearance of fine lines and wrinkles. Additionally, it functions as a co-emulsifier and surfactant, improving formulation stability, aiding in ingredient dispersion, and providing conditioning and spreading benefits.

Stability
For related PEG-modified dimethicones, a functional pH range of 5.5 to 8.5 is recommended for stable formulations. At 1% active concentration, approximately 20% hydrolysis was observed after 45 days at pH 5 and 86 days at pH 8.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel noted insufficient data for specific Alkoxy Polysiloxanes, including PEG-7 Dimethicone. However, reviews of the broader Dimethicone Copolyol category indicate low oral and dermal toxicity, with no primary skin or ocular irritation or sensitization observed in clinical studies. This ingredient, like other dimethicone-based compounds, is considered non-comedogenic. EWG advises caution for inhalable product forms due to potential respiratory concerns and impurities, but notes low concerns for other toxicities.
