Product overview
Silicon Dioxide is a mineral ingredient evaluated for anticaking, carrier, flow-control and selected fortification applications. It is commonly evaluated for Powder anticaking and flow aid, Food and nutraceutical premixes, Pharmaceutical glidant. Supply for food, feed or healthcare use requires the appropriate grade, specification and destination-market compliance review.
