product description

Benzalkonium chlorides (BACs), also known as alkyl dimethyl benzyl ammonium chlorides, alkyl dimethyl (phenylmethyl) quaternary ammonium chlorides, ammonium alkyl dimethyl (phenylmethyl) chlorides, or ammonium alkyl dimethyl benzyl chlorides, are a class of quaternary ammonium compounds (QACs). They are usually commercialized as a mixture of compounds with different lengths for the alkyl chain, ranging from C8 to C18, with higher biocide activity for C12 and C14 derivatives.

Product Usage
Benzalkonium Chloride is a cationic surfactant, appearing as white crystals or light yellow liquid, easily soluble in water and ethanol. It has good bactericidal and disinfectant effects, with strong compatibility and no obvious irritation. Its core application is disinfection, widely used in medical, health and daily chemical fields, which can quickly kill bacteria, fungi and viruses. It is often used for disinfecting skin, mucous membranes and the environment, as well as disinfecting medical devices. At the same time, it can be used as a phase transfer catalyst to accelerate organic reactions and improve reaction efficiency. In addition, it is also used in textile and water treatment fields, effectively inhibiting the growth of microorganisms and ensuring product quality. It is a highly practical chemical raw material with small dosage and remarkable effect, widely used in daily production and life.
