PH Value


Density (g/ml)




Methylisothiazolinone 70 preservatives is solubility in water, miscible in a wide range of water soluble solvents.


Temperature: up to 60°C (short periods to 80°C), pH range: 4 to 11;


1) Sterilization, antibacterial, high-efficiency, broad-spectrum and long-lasting.

2) Good miscibility with water and easy to use.

3) It is completely harmless at the popularization concentration.

4) It does not accumulate in the environment and is easily degraded.

5) The pH value can be used between 2-11.

6) It has good compatibility with surfactants and emulsifiers in personal care products.


MIT 70 biocide is suitable for water-based systems such as daily chemicals, cosmetics, coatings, and polymer synthetic emulsions.


1) In water-based systems such as coatings and polymer synthetic emulsions, the general use concentration is 0.05 to 0.20% (w/w); for daily chemical products, the general use concentration is 0.02 to 0.1% (w/w), depending on Whether the product is easily eroded by microorganisms and the storage environment of the product.

2) This product can be added in any process, but it should be avoided at the temperature above 50, and it is recommended to add it in the last process below 50.


1) Methylisothiazolinone 70 preservatives should avoid direct contact with eyes. Once contacted, rinse immediately with plenty of water without delay. Do not contact with skin for a long time.

2) MIT 70 biocide should not be in contact with reducing metals during storage, such as metal iron, aluminum, etc., to avoid product decomposition.

3) Methylisothiazolinone 70 solution has poor stability in alkaline media with pH>9.0, so it is not suitable for use. The compatibility of highly nucleophilic chemicals with this product, such as S2- and R-NH2, will cause the quality of this product to decrease, or even completely fail. 

Storage: To be stored at room temperature in a dark place; with a shelf time of one year.

Package: 25Kg per drum, 200Kg per drum or 1000Kg per IBC drum;
