Nutrients such as protein and various cationic, anionic, nonionic surfactants will not affect its antibacterial effect; (4) A suitable pH range. It is effective in the range of pH 4~9, that is, in the environment of weak acidity, neutrality and partial alkali, it can maintain strong antibacterial effect after adding; (5) Good water solubility and easy to use. It is easily soluble in water and has a solubility of 25g in water at 25 ° C. It is extremely convenient to use.

The general addition amount is 0.2-0.5‰, and the maximum allowable addition amount in the daily chemical product is 1‰, and there is no residue in the discharge, which will not cause cumulative pollution to the environment. Application pH range: 4-8; application temperature range: generally pre-dissolved in an appropriate amount of water, added below 60 °C. Precautions: This product can be applied in a wide range of pH, with the best range from acidic to neutral. It is unstable under high temperature and alkaline conditions, and the color becomes dark under the sun light.
