Product Description of Benzalkonium Chloride CAS#63449-41-2
Benzalkonium chloride, alternatively named dimethylbenzylalkylammonium chloride，is a quaternary-ammonium-based cationic surfactant and non-oxidizing biocide with broad-spectrum disinfection performance. It dissolves freely in water and keeps stable under different water-hardness conditions, featuring low acute toxicity and no obvious cumulative toxic effect.The substance can restrain bacteria, algae and biological slime inside aqueous systems, and carries good penetrating, dispersing and slime-stripping capacity. In addition, it delivers partial degreasing, deodorizing and anti-corrosion functions.
This product is available in two major grades: high-purity solid and aqueous solution. The 95-99% high-purity solid appears as white to pale-yellow powder or waxy gelatinous lumps, while the 50%-80 wt% aqueous solution is a colorless to pale-yellow clear viscous liquid that generates foam upon shaking.
