Calcium glycerophosphate

Calcium Glycerophosphate is a versatile mineral supplement used primarily in food fortification, pharmaceuticals, and oral care products. In the food industry, it serves as a nutrient supplement and stabilizer for beverages and dairy. In oral care, it is a key ingredient in toothpaste to promote enamel remineralization and neutralize plaque acids. For pharmaceutical applications, it acts as a highly bioavailable source of calcium and phosphorus to treat deficiencies and support bone health.

Buyers must ensure the product meets international pharmacopoeia standards such as USP (United States Pharmacopeia), FCC (Food Chemicals Codex), or BP (British Pharmacopoeia). Key parameters to check include Calcium content (typically 18.6% to 19.4% on a dried basis), pH levels (8.5 to 10.5 for a 1% solution), and strict limits on heavy metals (Lead < 3ppm, Arsenic < 3ppm). Always request a Certificate of Analysis (COA) for every batch to verify purity and solubility.

Depending on the target market, suppliers should provide ISO 9001 for quality management and ISO 22000 or HACCP for food safety. For religious markets, Halal and Kosher certifications are often required. If the product is intended for the US market, FDA registration of the facility is essential, while REACH registration is necessary for exports to the European Union.

It is typically available as a fine white powder. The particle size (mesh size) is critical; finer powders (e.g., 80-100 mesh) are preferred for smooth integration into toothpaste, while specific granulation might be required for tablet compression in the pharmaceutical industry to ensure flowability and content uniformity.

The primary risks include quality inconsistency between samples and bulk orders, and regulatory non-compliance at customs. To mitigate this, use third-party inspection services (like SGS or Intertek) to verify the cargo before shipment. Ensure the supplier provides a Material Safety Data Sheet (MSDS) in the correct language for the destination country to avoid customs delays.

Focus on long-term volume contracts rather than one-off spot purchases to secure stable pricing, as phosphorus-based raw materials can be subject to market volatility. Negotiate for staggered delivery schedules if you have limited storage capacity, and always clarify Incoterms (e.g., CIF vs. FOB) to understand exactly where the risk transfers and who covers the insurance.

Utilize secure payment methods such as Letters of Credit (L/C) for large volumes or Escrow services provided by reputable platforms like Made-in-China.com. This ensures that payment is only released to the supplier once shipping documents and inspection certificates are verified, protecting the buyer's capital.

The product is hygroscopic, meaning it absorbs moisture from the air. It must be shipped in moisture-proof packaging, typically 25kg fiber drums with double PE inner bags. During transit, it should be kept in a cool, dry, and well-ventilated area away from incompatible substances like strong acids. Ensure the shipping container is inspected for leaks or dampness before loading.
