3Q-611 MIT-50

Methyl isothiazolinone (MIT) is a highly effective bactericide, a heat-resistant water-based preservative, and has a good effect on inhibiting the growth of microorganisms. It can inhibit the growth of bacteria, fungi, molds and molds. This product can directly add personal care products, cosmetics, coatings, pulp and other fields

Methylisothiazolinone is a spectrum of germicidal preservatives that can effectively kill algae, bacteria and fungi. The active single agent can be widely used in industrial cooling water, oil field tank water, paper industry, pipelines, coatings, paints, rubbers, cosmetics, photosensitive films and cleaning products. The effective amount is small, non-toxic and non-polluting, and it can be easily mixed in various formulas. The PH has a wide range of use. After diluting the concentration, it is easily biodegraded into non-toxic and non-polluting substances. no residual emissions, good compatibility with various emulsifiers, surfactants and protein ingredients. 2-Methyl-4-Isothiazolin-3-one can effectively kill a variety of bacteria at low concentrations, and it's especially suitable for the storage of cosmetics and personal care products. Applicable pH range pH2.0-12.0, miscible with water, can be added in any process, easy to operate
