Its food grade silica product line, with synthetic amorphous silica as the core raw material, is widely recognized for its safety, strict regulatory compliance and versatile functionality, and has become a preferred choice for the global food and food-related industries.

Certifications and safety standards of food grade silica products

PQ has built four major functional series of food grade silica products, which are precisely adapted to the segmented needs of the whole food industry chain. The Sorbsil® series is specially developed for edible oil purification and impurity removal, with a dust-free formula to reduce production safety risks. Among them, Sorbsil® R40 is approved by the U.S. FDA as a direct food additive, which can efficiently remove polar contaminants such as phospholipids, soaps and trace metals in oils and fats, improve oil clarity and quality; Sorbsil® R92 is a modified grade with enhanced impurity adsorption capacity, which is more suitable for complex oil refining scenarios. The Neosyl® GP series is a universal anti-caking and flow aid for food and feed, which fully complies with FDA, FCC, EU E551/E551a standards, with strictly controlled heavy metal and microbial indicators, and is widely used in anti-caking treatment of powdered foods such as milk powder, spices and sugar. The Sorbosil® AC35 series is a food grade abrasive for oral care and cosmetics, which meets USP, EP and JP monographs, with high cleaning efficiency and low scratching, suitable for high-water-content gel toothpaste formulas. The Gasil® 114 series is a matting and anti-blocking agent for food contact coatings and films, which is FDA certified and can provide excellent matting effect and chemical resistance for food contact waterborne coatings.

Manufacturing process of food grade silica emphasizing safety and compliance

All PQ food grade silica products are synthetic amorphous silica, non-crystalline, safe and non-toxic, non-carcinogenic, with no bioaccumulation risk, and environmentally friendly. The full series has passed FDA, EU REACH, ISO 9001, ISO 14001, HACCP, Kosher and Halal certifications, fully meeting the market access requirements of major countries and regions in the world.
