E900B – Methylphenylpolysiloxane
AntifoamDescription
Synthetic silicone fluid
Notes
Cyclomethicone is a synthetic silicone compound made in laboratories by linking silicon atoms with oxygen and methyl groups in a ring-like structure (hence the 'cyclo' prefix). It's produced through a controlled chemical process that creates a clear, lightweight fluid that feels smooth and slippery. Think of it as a specialized liquid silicone that's been engineered specifically for use in food processing. This additive serves as an antifoaming agent, working to prevent or eliminate unwanted foam and bubbles during food manufacturing. You'll encounter cyclomethicone in various processed foods where foam control is important, including cooking oils, beverages, dairy products, and processed foods where excessive bubbling during production could interfere with proper mixing, packaging, or final texture. Cyclomethicone is entirely synthetic and manufactured in chemical facilities rather than extracted from natural sources. It's suitable for both vegetarian and vegan diets as it contains no animal-derived ingredients, and it doesn't conflict with religious dietary laws. Like other silicone compounds used in food, it's designed to pass through the digestive system without being absorbed, and regulatory agencies consider it safe for food use in controlled amounts.
