Can I use Cyclopentasiloxane with PEG-7 Dimethicone?
Works well together
Cyclopentasiloxane and PEG-7 Dimethicone are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.
CyclopentasiloxaneEmollient
- ✓Gives a lightweight, silky, fast-drying feel
- ✓Improves spreadability of other ingredients
- ⚠EU has restricted D5 in wash-off cosmetics at ≥0.1% due to environmental persistence concerns
PEG-7 DimethiconeEmollient
- ✓Water-soluble silicone copolymer that emulsifies oils into water-based systems while imparting a smooth, non-greasy skin feel
- ✓Low PEG chain count (7 EO units) gives it moderate hydrophilicity — suitable for water-light gels and watery creams
- ✓Contributes a characteristic silky-soft after-feel without the heaviness of high-molecular-weight silicones
