Fumed Silica (Aerosil) Manufacturer in Istanbul - Shop Now

Fumed Silica is a highly purified, amorphous form of silicon dioxide (SiO₂) produced by a flame hydrolysis process. Known for its fine particle size and high surface area, Fumed Silica is widely used as a thickening agent, rheology modifier, and anti-caking agent in a variety of applications, particularly in the cosmetic, personal care, and pharmaceutical industries. It improves the texture, stability, and flow properties of products, making it an essential ingredient for enhancing formulation performance.

Preparation Guidelines

1. Disperse Fumed Silica in the formulation gradually while stirring to prevent clumping.
2. For best results, add it to the oil phase in emulsions or to the base liquid for gels.
3. Mix thoroughly to achieve uniform distribution and the desired viscosity.
4. Avoid excessive heat when handling to preserve the integrity of the silica.

Safety and Handling
Fumed Silica is non-toxic and safe for use in a wide range of products. However, like any fine powder, inhaling the dust should be avoided. Use protective equipment such as a dust mask when handling in large quantities. Store in a cool, dry place, away from moisture and sources of direct heat. Ensure that containers are tightly sealed to prevent contamination.

Note: Fumed Silica is an excellent choice for improving the texture, stability, and performance of various formulations, particularly those requiring smooth flow, thickening, or stabilization. It is commonly used in both cosmetic and industrial applications for its versatile and effective properties.
