📖 About Dimethicone

Dimethicone (PDMS) is the most widely used silicone in cosmetics. It provides a smooth, silky skin feel, reduces tackiness of formulations, and creates a protective barrier without clogging pores.

🛒 Purchasing Guide & Tips

Choose viscosity based on application: 100cSt for light serums, 1000cSt+ for richer creams
Request MSDS and FDA DMF (Drug Master File) reference if needed
Can be blended with Cyclopentasiloxane for better spreadability
Store in sealed containers — moisture absorption can affect viscosity

Dimethiconol has a terminal hydroxyl group, making it more hydrophilic and better for water-based formulas.
