Cabosil (Fumed silica)

Cabosil (Fumed silica)

Aerosil; Silicon Dioxide; Synthetic Amorphous Silica

CAS 7631-86-9

Chemical Formula SiO2

Molecular Weight 60.08 g/mol

Fumed silica is a fluffy, white powder composed of microscopic, fused silica particles with a high surface area. It's produced by burning volatile silicon compounds in a flame and is used as a thickening agent, anti-caking agent, and anti-settling agent in various applications like cosmetics, pharmaceuticals, and coatings. Fumed silica is also known for its light-diffusing properties and its ability to improve the flow of powders.  

Industrial Uses

1. Paints,Coatings & Adhesives 

  • Rheology Control: Cabosil is a crucial rheology modifier, controlling the flow and consistency of paints and coatings. It provides thixotropic properties, meaning the material becomes less viscous under shear (like when applied) and more viscous at rest, preventing sagging and settling. 
  • Anti-settling Agent: By creating a network of silica particles within the liquid, Cabosil helps prevent pigments and other solid components from settling out, ensuring a uniform and consistent product. 
  • Reinforcement: Cabosil particles can enhance the hardness, scratch resistance, and overall durability of coatings by reinforcing the film structure. 
  • Hydrophobicity: Some Cabosil grades, like CAB-O-SIL TS-720, are treated to be hydrophobic, improving the coating's ability to repel water and protect against corrosion.
  • Viscosity Adjustment: Cabosil is used to adjust the viscosity of paints and coatings, ensuring smooth and even application. 
  • Anti-settling: It helps prevent pigments and other particles in coatings from settling out during storage, maintaining product consistency.

2. Personal Care

  • Thickening and Rheology Control: Cabosil acts as a rheology modifier, thickening liquids and controlling their flow properties. It helps prevent ingredients from settling out in liquid formulations like creams, lotions, and serums.
  • Anti-caking and Flow Enhancement: In powder-based products like makeup, antiperspirants, and hair products, Cabosil prevents clumping and ensures a smooth, free-flowing consistency. It acts as a glidant, improving the flow of powders during manufacturing and application.
  • Moisture Resistance and Stability: Cabosil enhances the moisture resistance of formulations, protecting them from degradation due to humidity and extending their shelf life. It helps maintain consistent viscosity in liquid products, ensuring product performance over time.

3. Pharmaceuticals

  • Glidant: Cabosil improves the flow of powder mixtures in tablet and capsule manufacturing, ensuring uniform filling of dies and capsules. 
  • Anti-caking agent: By absorbing moisture, Cabosil prevents powders from clumping, which is crucial for consistent tablet weight and content uniformity.
