Your Formulation Solution for Stable, Emulsifier-Free Emulsions with AEROSIL® R 816
The fumed silica powder offers an alternative technology to stabilize oil/water emulsions. Due to the special surface modification of the silica both hydrophilic and hydrophobic properties are introduced in just one material. This enables AEROSIL® R 816 to enrich at oil/water interfaces and thereby stabilize oil droplets in a continuous water phase by the Pickering effect. Furthermore, AEROSIL® R 816 brings structure to the continuous water phase and increases its viscosity which limits the mobility of the oil droplets, thereby providing for even more emulsion stability.
AEROSIL® R 816 presents the formulator with a simple, easy-to-use W/O emulsion for the creation of emulsifier-free lotions and creams.
- Ideal for sensitive skin
- No need for a thickener. Simply adjust the use levels (1% for a lotion, 3% for a cream)
- No heating or cooling, less energy, increased sustainability profile
Benefits of AEROSIL R 816:
- Silica is the most abundant mineral on earth—easy and cost-effective to utilize
- Eliminate emulsifier and thickener
- Reduce greasy, oily skin feel
- Improve SPF by replacing PEG emulsifiers in sunscreens with AEROSIL® R 816
