Where is Calcium sodium phosphate used?

• Food manufacturing: buffering and leavening agent in baked goods, processed cheeses and dry-mix products
• Pharmaceuticals: mineral excipient and pH-adjusting agent in tablet and powder formulations
• Animal feed: bioavailable phosphorus and calcium supplement for livestock and poultry
• Fertilizer blends: slow-release phosphate delivery to soil
• It provides controlled phosphate delivery where calcium and sodium cation balance matters.

Good to know: Buyers should confirm particle size distribution and purity grade when sourcing, as these vary between suppliers and affect dissolution behavior.
