Safety & protection

Disposal Methods · 1 item

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Preventive Measures · 1 item

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Allowable Tolerances · 1 item

Residues of calcium phosphate are exempted from the requirement of a tolerance when used as a solid diluent or carrier in accordance with good agricultural practices as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest. /Calcium phosphate/

Applications · 3 items

UsesDibasic calcium phosphate is found in nature as the mineral monetite. It is used as a food supplement and source of calcium, both in human food and animal feed. It is used in dough conditioner; in several dental products and in medicine. Other applications are in fertilizers, plastics and in the manufacture of glass.

UsesReplenisher (calcium); pharmaceutic aid (tablet base).

UsesIt is used as a feed additive for livestock and poultry. It can promote feed digestion, put on animals weight, raise laying rate or producing milk rate, cure diseases such as rickets, osteomalacia and anemia.

Preparation methods · 1 item

PreparationDibasic calcium hydrogen phosphate may be prepared by several methods. It is precipitated by mixing solutions of calcium chloride and disodium hydrogen phospate: CaCl2 + Na2HPO4 → CaHPO4 + 2NaCl It also is prepared by treating phosphoric acid with lime water (suspension of calcium hydroxide in water). Also, it is obtained as a by-product in the preparation of hydroxypatite. The preparation involves the reaction of phosphoric acid with calcium phosphate. H3PO4 + Ca3(PO4)2 → 3CaHPO4
