1. Property and Purpose

      It is a kind of cationic surfactant and non-oxidizing bactericide with broad-spectrum and high efficiency to control the propagation of bacillus-algae and the growth of slime in the water. It also has an effect of penetration and peeling to slime; in addition, it has efficient performance in degreasing, deodorization and corrosion inhibition.
      It is with low toxicity and without cumulative toxicity, soluble in water and can not be affected by the hardness of water so that it can be widely used for the industrial circulating cool water system in the industries such as oil,  chemical, electric power, textile and the like to control the propagation of bacillus-algae. It can also be used to kill the sulfate reducing bacteria. 
      It can be used as the mould inhibitor, softener, antistatic agent, emulsifier and conditioner in the woven and dyeing industries.

II.

When it is used as the non-oxidizing bactericide, the dosage of 50-100mg/L is preferred; used as slime stripping agent, the dosage of 200-300mg/L is preferred. Appropriate organosilicon antifoaming agent can be used when necessary. It can be used together with other bactericide such as isothiazolinone, glutaraldehyde, dithiocyano-methane and the like for better effect, but it can not be used together with chlorophenols medicines. When the product is added, dirt appear in the circulating water, which should be filtered and fished out so as to prevent the deposit of the dirt after the disappearance of the bubble.
Do no mix with the anionic surfactant.

Ⅳ. Safety and Protection

The product is with the almond favor and it is not strongly irritative to skin; when contact with the skin, flush with water.
