Description
Dicalcium phosphate (CAS 7757-93-9) is an inorganic calcium salt supplied as a white powder, commonly identified by the abbreviations DCP and D.C.P. 340 and approved as food additive E341ii. It is also marketed under trade names including MAGGRAN CP and MAGNESIA 85500, and carries EC number 231-826-1.
In food and pharmaceutical manufacturing, dicalcium phosphate functions as a pH buffer by neutralising excess acid in tablet formulations and baked goods, maintaining process stability within defined pH ranges. In animal feed, it delivers bioavailable calcium and phosphorus directly to bone mineralisation pathways, replacing less digestible inorganic phosphate sources.
Dicalcium phosphate is available in food-grade, feed-grade, and pharmaceutical-grade specifications, with compliance to E341ii, FCC, Ph.Eur., and REACH regulations depending on grade. It is supplied under HS code 2835 25 00 and typically offered in 25 kg bags or bulk quantities to meet industrial procurement volumes.
