2-Methyl-4-isothiazolin-3-one/MIT/Methylisothiazolinone CAS 2682-20-4 from China factory

2-Methyl-4-isothiazolin-3-one (MIT), also known as Methylisothiazolinone, is an isothiazolinone-based organic compound widely used as a broad-spectrum antimicrobial agent. With CAS No. 2682-20-4, MIT is designed to inhibit the growth and reproduction of microorganisms such as bacteria, fungi, and yeasts in a variety of industrial and formulated products.

Compared with many conventional biocides, isothiazolinone compounds are valued for their rapid antimicrobial action and ability to control microbial growth and metabolism while helping prevent biofilm formation. MIT can be incorporated into different formulations and is suitable for applications where effective microbial control is required at relatively low use levels.

Product Overview

MIT is a versatile antimicrobial active used across industrial water treatment, coatings, paints, paper processing, rubber products, cleaning formulations, and selected cosmetic and personal care applications.

Its broad applicable pH range of 2.0–12.0 allows it to work across a wide range of formulation environments. MIT is miscible with water and can be added during different stages of production, making it convenient for formulation and processing.

The product can also be compatible with various emulsifiers, surfactants, and protein components, supporting its use in complex formulation systems.

Key Features of MIT

Broad-Spectrum Microbial Control

MIT can inhibit and eliminate a wide range of microorganisms, including bacteria, fungi, and yeasts. This broad-spectrum activity makes it suitable for applications where microbial contamination can affect product quality, storage stability, or production processes.

Effective at Low Concentrations

MIT can provide effective microbial control at relatively low concentrations, helping formulators maintain the required preservation performance without unnecessarily increasing the amount of active ingredient in a formulation.

Wide pH Compatibility

With an applicable pH range of 2.0–12.0, MIT can be considered for acidic, neutral, and alkaline formulation environments. This provides flexibility for industrial processes and formulated products with different pH requirements.

Water Miscibility

MIT is miscible with water and can be easily incorporated into water-based formulations. Its convenient handling characteristics make it suitable for various manufacturing and processing systems.

Easy Formulation

MIT can be added at different stages of a production process and mixed into a variety of formulations. It is compatible with different emulsifiers, surfactants, and protein components, depending on the formulation system and application conditions.

Biofilm Control

In addition to controlling microbial growth, isothiazolinone-based biocides can help inhibit microbial metabolism and the formation of biofilms. This is particularly relevant in water systems, pipelines, and industrial environments where microbial deposits can affect operating conditions.

Applications

MIT CAS 2682-20-4 can be used in a broad range of industrial and formulated-product applications.

Industrial Cooling Water

MIT can be used for microbial control in industrial cooling water systems. Controlling bacteria, fungi, and other microorganisms helps maintain cleaner water systems and reduce problems associated with microbial growth and biofilm formation.

Oilfield Applications

MIT can be applied in oilfield-related water systems, including return tank water, where microbial contamination may affect water quality and process operation.

Paper Industry

In paper manufacturing, microbial growth can affect process water and production conditions. MIT can be incorporated into suitable paper-processing formulations for microbial control.

Pipelines and Water Systems

MIT is suitable for applications involving pipelines and circulating water systems where microbial growth and biofilm formation need to be controlled.

Coatings and Paints

Water-based coatings and paints can be susceptible to microbial contamination during storage and use. MIT can serve as an antimicrobial component in appropriate coating and paint formulations.

Rubber Products

MIT can be used in selected rubber-related formulations and processing systems where microbial protection is required.

Cosmetics and Personal Care Products

MIT has been used as an antimicrobial preservative in cosmetic and personal care formulations. It can help control the growth of bacteria, fungi, and yeasts in suitable formulations.

For cosmetic applications, formulators should always verify the current regulatory requirements, permitted concentrations, labeling requirements, and applicable restrictions in the target market before use.

Cleaning Products

MIT can be incorporated into selected cleaning formulations to help control microbial growth and improve formulation preservation.

Photosensitive Films

MIT can also be used in certain photosensitive film-related formulations where microbial control is required.

Product Specifications

Why Choose MIT from a China Manufacturer?

For industrial customers, sourcing MIT directly from a China factory or chemical manufacturer can provide a practical supply option for formulation and production requirements.

A professional MIT supplier can support customers with product specifications, application information, packaging options, documentation, and bulk-order requirements. For customers working with different formulation systems, technical communication is also important to ensure that MIT is suitable for the intended application and dosage conditions.

MIT can be supplied for different industrial applications, including water treatment, coatings, paints, paper processing, cleaning products, and other microbial-control formulations.

Handling and Formulation Considerations

The appropriate dosage of MIT depends on the specific formulation, target microorganisms, processing conditions, and regulatory requirements. Before commercial application, compatibility and preservation performance should be evaluated through formulation testing.

When used in cosmetics, personal care products, or other regulated applications, users should confirm compliance with the latest regulations in the destination market. Proper handling, storage, personal protective equipment, and safety procedures should also follow the supplier's Safety Data Sheet (SDS) and applicable local requirements.
