ViCALity Medium
ViCALity Medium
ViCALityâ„¢ Medium PCC is the largest of the three open structured scalenohedral calcites which were developed to yield a range of low powder densifies. It is a 2.6 micron particle, with high surface area and oil absorption.
ViCALity precipitated calcium carbonate (pcc) are a family of low lead calcium carbonates available in a wide variety of sizes and shapes to meet the needs of formulators of food, drugs, nutritional and personal care products. Containing less than 500 ppb lead, these products are suitable for many applications that must meet the lead requirements of California Proposition 65.
