Simethicone

CAS NO.: 8050-81-5
Specification: CP/USP/EP
Simethicone is a clinically proven, organosilicone polymer specifically engineered as a highly effective antifoaming and defoaming agent. It functions by reducing surface tension at gas-liquid interfaces, enabling the coalescence and release of trapped gases. Renowned for its inertness, safety, and efficacy, it is a critical excipient and active ingredient across pharmaceutical, nutraceutical, food, and industrial applications.
Mechanism of Action:
Simethicone acts physically, not chemically. Its low surface tension allows it to spread across gas bubbles, destabilizing foam walls and promoting bubble coalescence. This leads to rapid foam collapse and the release of entrapped gases. It is non-systemic, not absorbed, and excreted unchanged, ensuring an exceptional safety profile.
Core Applications & Benefits
1. Pharmaceutical & Nutraceutical
Gas & Bloating Relief: Active ingredient in OTC anti-flatulent products (e.g., chewable tablets, oral drops). Effectively alleviates symptoms of abdominal pain, bloating, and discomfort caused by excess gas.
Critical Excipient: Prevents foam formation in manufacturing processes (e.g., syrup production, fermentation) and in final formulations (e.g., antacids like aluminum hydroxide/magnesium hydroxide combinations).
Tablet & Capsule Manufacturing: Used as a lubricant and anti-adherent, improving powder flow and preventing sticking during compression and encapsulation.
Contrast Agent Imaging: Administered prior to abdominal ultrasound or CT scans to reduce gas interference, providing clearer diagnostic images.
2. Food & Beverage
Processing Aid: Eliminates unwanted foam during the production of juices, syrups, cooking oils, and fermented products, increasing processing efficiency and vessel capacity.
Anti-Foaming in Cooking: Added to anti-stick sprays and cooking oils to prevent foaming during frying.
3. Industrial
Fermentation: Essential in antibiotic, enzyme, and biofuel production to control excessive foam, maintain optimal reactor volume, and prevent contamination.
Wastewater Treatment: Accelerates foam breakdown in aeration tanks, improving treatment efficiency.
Paints & Coatings: Prevents foam formation during manufacturing and application, ensuring a smooth, defect-free finish.
4. Cosmetics & Personal Care
Used in creams, lotions, and anti-blemish products to improve texture and spreadability, providing a smooth, non-greasy feel.
