Import Benzalkonium Chloride — Buy in Bulk from Supplier in China

Benzalkonium chloride from Shandong Taihe Chemicals Co., Ltd is a cationic surfactant and nonoxidizing biocide with the molecular formula C21H38NCl. This supplier offers three physical forms: colorless to pale yellow transparent liquid, light yellow transparent liquid, and light yellow waxy solid. The solid content ranges from 44.0% minimum up to 88% minimum depending on grade, with amine salt content held at 2.0% maximum across all variants. pH of a 1% water solution falls between 6.0 and 8.0 for all forms. The product is sold in 25kg or 200kg plastic barrels from Zaozhuang, Shandong province.

The biocide functions by disrupting microbial cell membranes, making it effective against bacteria and algae in industrial water systems. Its cationic nature provides dispersing and penetrating properties that allow it to remove existing sludge and algal deposits. The product exhibits low toxicity with no accumulation in the environment, and remains fully soluble in water regardless of hardness. Typical industrial grades of benzalkonium chloride range from 40% to 80% active content; higher concentrations reduce shipping volumes for bulk buyers. The waxy solid form suits applications where freeze-thaw stability matters during winter transport or storage.

As a nonoxidizing biocide, typical dosage ranges from 50 to 100mg/L in circulating cooling water systems. For sludge removal applications, 200 to 300mg/L is standard, with an organosilyl antifoaming agent added to manage froth. The product combines synergistically with isothiazolinones, glutaraldehyde, and dithionitrile methane, but is incompatible with chlorophenols and anionic surfactants. Residual sewage after dosing requires prompt filtration or blowdown to prevent settlement in collection tanks.
