Import Calcium Hydroxide — Buy in Bulk from Supplier in China

Guilin Hongxing Chemical Co., Ltd. supplies food‑grade calcium hydroxide that appears as a white, dry, free‑flowing powder. The assay is 96.5 % Ca(OH)₂ and the carbonate salts content is qualified, while magnesium and alkali salts are measured at 0.9 %. Impurities are limited to 0.09 % acid‑insoluble substances, arsenic below 2 mg kg⁻¹, fluoride 13 mg kg⁻¹, lead below 2 mg kg⁻¹ and total heavy metals under 10 mg kg⁻¹. Particle size analysis shows 99.8 % of the material passes a 0.045 mm (325 mesh) sieve, and loss on drying is 0.08 %.

These figures meet the Chinese standard GB 25572, which is widely referenced for calcium hydroxide used in food processing. Typical industry limits for moisture are below 0.5 % and bulk density is around 0.5 g cm⁻³, values that the supplier’s data implicitly satisfy. The material’s pH in a 5 % solution is usually above 12, a property that makes it suitable as a buffering and neutralising agent. Standard safety data indicate a melting point near 522 °C, aligning with the supplier’s reported range.

The product is employed as an acidity regulator in milk‑powder production, as a firming agent in cheese and confectionery, and as a calcium source for supplements. Food manufacturers, dairy processors and beverage formulators are the primary buyers of this grade. Pricing, minimum order quantity and lead time are not disclosed in the listing, so interested parties should request a formal quotation. Incoterms, payment conditions and packaging details can be clarified directly with Guilin Hong Xing Chemical Co., Ltd.
