- AEROSIL® R 816 Benefits
Many disinfectant gels are based on Carbomer as viscosity builder. The gels are shear thinning, which provides easy pouring and proper handling when applied on the skin. With the shortage of Carbomer, producers are seeking alternatives. By using AEROSIL® R 816, the Carbomer concentration of an app. 60% alcohol containing disinfectant gel can significantly be reduced (50%) while maintaining the viscosity of the gel:
- Mix AEROSIL® R 816 with water
- Add Carbomer and stir until homogeneous
- Add Ethanol 75%
- Neutralize with Triethanol amin (99%) and stir until uniform; pH 6,2-6,9
- Add glycerin

- AEROSIL® Fumed Silica in Lubricating Greases
AEROSIL® fumed silica helps to build a stable matrix to increase viscosity and suppress oil separation in lubricating greases. It can be used in the following systems:
- In non-soap greases, used in high-temperature applications up to 230° C as well as for extreme-pressure and multipurpose greases.
- In soap greases, thickened by fatty acid soaps of lithium, calcium, sodium or aluminum, AEROSIL® fumed silica can be used to further improve the performance of the lubricating grease.
- Hydrophilic fumed silica provides optimized thickening effects in non-polar oils.
- Hydrophobic fumed silica provides viscosity control and increased water repellency in semi-polar to polar oils.
- The surface area of the silica and the volume fraction of the silica in the fi nal mass play a role in the long term storage and heat stability.
- Premium Product Recommendations
Provides overall the best effects in most base oil systems and gives outstanding stability.
- Lubricating Grease Applications
The use of AEROSIL® fumed silica is recommended for lubricating greases used in industrial applications, automotive, electrical as well as food grade.
- Electrical - Offers rheology control as well as water resistance.
- Industrial - Offers rheology control as well as excellent oxidation resistance against water and chemicals.
- Automotive - Offers rheology control as well as excellent oxidation resistance against water and chemicals.
- Food - Hydrophilic AEROSIL® are generally recognized as safe (GRAS; direct food contact). Offers rheology control as well as water resistance
