- Hydroxyethylcellulose
- Water-soluble cellulose ether for thickening and suspension stabilization; sensitive to ions, electrolytes reduce viscosity, use at pH 7-8.
- Silica
- Silica powder at 1–10%; absorbs oil, thickens, provides matte finish, for oil-control products
- Sodium Dilauramidoglutamide Lysine
