Sipernat 22 Silicon Dioxide
What is Sipernat 22?
Sipernat 22 is a high-purity synthetic silicon dioxide (SiO₂), also known as amorphous silica. It is produced by Evonik Industries and is widely recognized for its exceptional properties as a flow aid, carrier, and anti-caking agent. Sipernat 22 appears as a white, odorless, fine powder with high porosity and a large surface area.
Chemical Composition
- Chemical Name: Silicon Dioxide
- Chemical Formula: SiO₂
- Molecular Weight: 60.08 g/mol
Sources and Processing
Sipernat 22 is synthetically produced through a precipitation process, where sodium silicate reacts with sulfuric acid under controlled conditions. The reaction forms a gel-like structure, which is then filtered, washed, dried, and milled into a fine powder. Unlike naturally occurring silica (such as sand or quartz), Sipernat 22 is engineered to have specific physical and chemical properties suitable for industrial and food-grade applications.
Common Uses
Sipernat 22 (ซิลิกอนไดออกไซด์) is used in a wide range of industries:
- Food Industry: As an anti-caking agent in powdered foods like spices, milk powders, and instant soups.
- Pharmaceuticals: As a glidant to improve powder flow in tablet manufacturing.
- Cosmetics: For enhancing texture and oil absorption in creams and powders.
- Chemicals and Plastics: As a carrier for liquids, rheology control agent, and dispersant.
Benefits of Sipernat 22
- Enhances flow properties of powders.
- Prevents clumping and improves shelf life.
- Acts as an excellent carrier for liquid and oil-based substances.
- Increases product stability in formulations.
- Safe for food and pharmaceutical use (when used as approved).
