Properties: Colorless to light yellow liquid. The aqueous solution shows neutral or weakly alkaline reaction and generates a large amount of foam when shaking. This product is highly soluble in water or ethanol and slightly soluble in ether.

Usage: It is a cationic surface modifier, belonging to the non oxidizing bactericidal agent, with broad-spectrum and efficient bactericidal and algal killing ability. It can effectively control the reproduction of bacteria and algae in water and the growth of sticky mud, and has good sticky mud stripping effect and certain dispersion and penetration effects. At the same time, it has certain oil removal, deodorization and corrosion inhibition effects. Low toxicity, no cumulative toxicity, and easily soluble in water, not affected by water hardness. Therefore, it is widely used in circulating cooling water systems in industries such as petroleum, chemical, power, and textile to control the growth of bacteria and algae in cruise cooling water systems, and has a special effect on killing sulfate reducing bacteria. It can be used as a sterilizing and anti-virus agent, softener, antistatic agent, emulsifier, conditioner, etc. in the textile printing and dyeing industry.
