Grace Food Grade Silica: Century-Old Technical Expertise for Food & Pharmaceutical Safety

Created on 04.30

For more than a century, W. R. Grace & Co.-Conn. has been a world-leading specialty chemical enterprise with a profound heritage in silica technology innovation. Its full series of food grade silica products have built an excellent reputation in the global food and pharmaceutical industries with industry-leading purity, precisely engineered structural properties, full global regulatory compliance and versatile application adaptability, providing all-round solutions for customers worldwide in process upgrading, product quality improvement, safety compliance and sustainable production.

Production facility for food grade silica with advanced technology

The core of Grace's technology lies in its industry-leading pore structure engineering and purification process. Its food grade silica products are all high-purity synthetic amorphous silica, with a dry basis SiO₂ content of up to 99.7%, no respirable crystalline silica, and highly inert chemical properties that will not trigger adverse oxidation reactions in food substrates. The flagship SYLOID® FP series is a multi-functional food and pharmaceutical grade silica, among which the 244 FP model has the strongest adsorption capacity in the series, can adsorb up to 3 times its own weight of liquid, and is the first choice for glidants and high-capacity liquid carriers in probiotic preparations, plant extracts and multivitamin formulas; the 63 FP model is specially designed for moisture-sensitive active ingredients, with excellent moisture adsorption capacity at low relative humidity, which can effectively extend the product shelf life. The TRISYL® series is a food grade silica adsorbent specially developed for edible oil refining, with a specific surface area of 700 m²/g, which can efficiently remove polar contaminants such as phospholipids and trace metals in oils and fats. Compared with traditional activated bleaching earth, it can achieve up to 85% total cost saving and 90% reduction in spent filter cake, greatly reducing hazardous waste disposal costs and oil loss.
