Import 4a Zeolite — Buy in Bulk from Supplier in China

4A zeolite supplied by Fujian Risheng Chemical Co., Ltd. is an industrial-grade sodium aluminosilicate designed as a phosphate-free builder for detergent formulations. Its primary function is to soften water by exchanging calcium and magnesium ions, which enhances the cleaning efficiency of low-phosphorus or phosphorus-free detergents. The material also binds heavy metals, improving the stability and performance of liquid and powder detergents.

The structure of this zeolite features a uniform 4 angstrom pore opening, which selectively adsorbs small molecules while excluding larger organic compounds. Standard bulk density for this grade is 0.65 to 0.75 g/cm³, and the typical particle size is 3 to 8 microns, optimised for dispersion in liquid systems. In water treatment, it is used to remove ammonia and heavy metals, while in personal care, it contributes to the stability of creams and lotions by controlling viscosity and preventing phase separation.

This product is particularly valued by detergent manufacturers seeking to meet environmental regulations that limit phosphorus content. It is commonly packed in 25 kg or 50 kg woven bags with a plastic liner to prevent moisture ingress. For large-scale users, bulk containers or big bags can be arranged. Buyers should confirm the heavy metal content and residual phosphate levels, as these can vary between batches and impact compliance with eco-labelling standards.

Fujian Risheng Chemical Co., Ltd. operates from Risheng Building in Shihu Harbor Industrial Zone, Xiamen, Fujian Province. The company is classified as an imported-tier supplier, indicating its focus on export markets. Its trust tier is harbour, which signifies a baseline level of export verification but does not include additional performance metrics.

The supplier’s profile does not provide details on response rates, certifications, or production capacity. As a result, buyers should directly confirm technical specifications, lead times, and compliance with relevant industry standards. No claims about client relationships or historical performance are available in the listing data, so independent verification is essential.
