Science
Mechanism of Action
This ingredient functions by creating a vapor-permeable, protective film on the skin, effectively minimizing transepidermal water loss and shielding against environmental irritants. As a PEGylated dimethicone, its structure allows it to maintain the benefits of silicones—such as barrier formation and smooth feel—while being water-dispersible. Its inherently low surface tension promotes exceptional spreading capabilities for a more even product distribution.

The Formula
Formulation
Stability
DIMETHICONE PEG-7 SULFATE is a water-dispersible silicone, allowing for easy rinse-off and preventing build-up. It exhibits optimal stability within a functional pH range of 5.5 to 8.5, and its PEG moiety enhances its hydrophilic properties, making it soluble in water and alcohols.

Safety
Safety Profile
The CIR Expert Panel has deemed dimethicone and its related polymers safe for use, noting their large molecular weight significantly limits skin absorption. Broader classes, including PEGylated dimethicones (Dimethicone Copolyols), were found safe even at concentrations up to 40% in aqueous solutions, showing no primary skin irritancy. Similar PEGylated sulfates (alkyl PEG sulfosuccinates) are also considered safe when formulated to be non-irritating.
