E466 – Sodium carboxymethyl cellulose
StabiliserDescription
Semi-synthetic, water-soluble polymer derived from cellulose
Notes
Sodium carboxymethyl cellulose (CMC) is made from cellulose, the same natural fiber that gives structure to plant cell walls in wood, cotton, and paper. To create this food additive, manufacturers take purified cellulose and chemically modify it by adding carboxymethyl groups, which makes it water-soluble and gives it useful properties for food applications. This process transforms the normally insoluble plant fiber into a versatile ingredient that can dissolve in water and create useful textures. CMC works as both a thickener and stabilizer in foods, helping to create smooth, consistent textures and preventing ingredients from separating. You'll commonly find it in ice cream (where it prevents ice crystals from forming), salad dressings, baked goods, and gluten-free products where it helps replace some of the binding properties that gluten would normally provide. It's also used in low-fat foods to help maintain a creamy mouthfeel without the fat. This additive is considered semi-synthetic since it starts with natural cellulose but undergoes chemical processing. It's suitable for vegetarians and vegans as it's plant-derived, and it doesn't contain any common allergens. CMC is widely approved by food safety authorities around the world and is considered safe for consumption, with no specific dietary restrictions for most people.
