Created on Today

As a global leader in specialty chemicals and advanced materials, Cabot Corporation has long been committed to developing safe, compliant, and high-performance material solutions for the food and pharmaceutical industries. Its CAB-O-SIL® series of food-grade fumed silica has become a core auxiliary material trusted by the global food processing industry, offering ultra-high purity, strict regulatory compliance, and excellent application performance, thereby addressing multiple core pain points in food production and processing for customers worldwide.

Cabot food grade silica is hydrophilic fumed silica produced by the vapor phase hydrolysis process of silicon compounds, with a pure production process and stable product quality. Its core food and pharmaceutical grade models, CAB-O-SIL M-5P and M-SP, have a SiO₂ purity of 99.0%-100.5%, which is far higher than the industry standard requirements; the BET specific surface area is stably controlled at 185.0-215.0 m²/g, the pH value is 3.5-5.5, the 325 mesh residue is less than 0.0200%, and the impurity content is extremely low. The product has a unique aggregated structure, submicron particle size and low bulk density, with a hydrophilic surface and excellent dispersibility and compatibility in most food formula systems.

High-purity fumed silica used in food applications

The full series of products comply with USP, EP and JP pharmacopoeia standards, are recognized as legal food additive INS No. E551, and fully meet the requirements of U.S. FDA food contact regulations, China GB 2760 food additive standards and EU food safety regulations. The production plant has obtained Kosher and Halal certification, and the product has no animal or plant-derived ingredients, is free of GMOs, food allergens and BSE/TSE risks, fully meeting the safety needs of vegetarian, halal and kosher food markets. It is widely used in three core fields: anti-caking and flow improvement for powdered foods such as milk powder, seasoning powder and solid drinks; rheology control for liquid food systems such as sauces and dressings; and reinforcement for food contact silicone rubber products such as sealing rings and baking molds. Cabot has a complete global sales and service network, and can provide localized technical support and after-sales service for food enterprises in various regions.
