Import Bronopol — Buy in Bulk from Supplier in China

Bronopol is a broad-spectrum antimicrobial preservative with the chemical formula C3H6BrNO4 and a molecular weight of 199.99 g/mol. This listing from Weifang Haina International Corp. Ltd. offers the compound as a white to light yellow or yellowish-brown crystalline powder with a melting point of 130-133 degrees C and a flash point of 167 degrees C. The material is odorless and tasteless, with a water solubility of 250 g/L at 22 degrees C, making it highly compatible with aqueous formulations.

The product is supplied as a fine crystalline solid, typical for industrial-grade bronopol used across personal care, agriculture, and industrial applications. Its solubility profile shows limited compatibility with petroleum ether, slight solubility in chloroform, acetone and benzene, and good solubility in water, ethanol and ethyl acetate. This polarity gradient supports its use in diverse formulation chemistries, from hydrophilic cosmetic bases to ethanolic disinfectant solutions. Standard purity grades for commercial bronopol typically exceed 99% assay by titration, though buyers should confirm the exact specification with Weifang Haina International Corp. Ltd.

Primary applications span cosmetic preservation (shampoo, balm and cream formulations at 0.01-0.02% concentration), agricultural seed treatment (cotton and rice at 800-1000 mg/L), and industrial biocidal uses including circulating water systems, paper pulp, coatings, plastics and wood treatment. The product functions as both a bactericide and algicide. Buyers should verify the supplier's current regulatory compliance status for their intended market, as bronopol is subject to REACH, EPA and cosmetic directive restrictions in various jurisdictions.

Weifang Haina International Corp. Ltd. is located at No.4455 East Fushou Street, Weifang Development Zone, Shandong Province, 261061, China. The supplier has a trust tier classification of harbor, which indicates a baseline verification level on the platform. The response rate is recorded at 0.00% with zero average response hours, suggesting that direct inquiry responsiveness has not been established in the available data. Buyers should test communication channels directly before relying on rapid turnaround.

The company's profile centres on chemical manufacturing and export from the Weifang industrial zone, a region with established chemical production infrastructure. No specific factory capacity, workforce size, revenue figures, or client references are stated in the source data. The listing does not indicate ISO, GMP, or other quality system certifications. Importers should conduct independent due diligence on manufacturing standards, regulatory compliance documentation, and sample verification before committing to bulk orders.
