A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Simethicone (CAS 8050-81-5) is polydimethylsiloxane, a polymer of roughly 200-350 dimethylsiloxane units, blended with finely divided silica. It functions as an antifoaming and defoaming agent, used to control foam in pharmaceutical and chemical manufacturing processes, as a food-grade antifoaming and anticaking additive (JECFA), and as an antifoaming ingredient in cosmetics.
Frequently Asked Questions
What does simethicone do?
Simethicone (CAS 8050-81-5) is polydimethylsiloxane blended with finely divided silica that functions as an antifoaming and defoaming agent. The silica-activated silicone destabilizes foam for rapid foam knockdown in aqueous and non-aqueous systems.
What is simethicone used for industrially?
It controls foam in pharmaceutical and chemical manufacturing processes, serves as a JECFA-classified antifoaming and anticaking food additive, and acts as an antifoaming ingredient in cosmetic and personal-care formulations. It is supplied as a process defoamer raw material.
What is simethicone made from?
It is a silicone defoamer composed of polydimethylsiloxane (a polymer of roughly 200-350 dimethylsiloxane units) combined with finely divided silica. The silica activates the silicone fluid for faster foam collapse.
Is simethicone water soluble?
No. The polydimethylsiloxane base is hydrophobic and not water soluble; simethicone is typically used as an emulsion or dispersion to deliver the silicone into aqueous foaming systems. Confirm the delivery form on the product technical data.
How is simethicone supplied and quoted in bulk?
It is available in bulk packaging such as drums and totes for process and formulation use. Pricing is volume- and market-dependent; request a quote with your grade and target quantity. A CoA and SDS accompany each shipment.
