Structural Formula:
CMIT/MIT, or isothiazolinone compounds, is a highly effective bactericidal mixture composed of 5-chloro-2-methyl-4-thiazolin-3-one (CMI) and 2-methyl-4-thiazolin-3-one (MI). Its unique bactericidal mechanism is based on the precise destruction of bacterial and algal protein structures. When CMIT/MIT comes into contact with microorganisms, it quickly penetrates into the cells, interferes with key chemical bonds in the protein synthesis process, blocks the normal metabolic activities of microorganisms, inhibits their growth, and eventually leads to death.
As a class of non-oxidizing broad-spectrum biocides, CMIT/MIT exhibits excellent performance advantages. It not only has efficient bactericidal activity, can quickly and effectively inhibit the growth of common bacteria, fungi and algae, but also has low toxicity. While ensuring safety in use, it is more environmentally friendly. The compound has good degradability and will not produce persistent residues in the environment after use, which is in line with the modern green environmental protection concept.
In practical applications, CMIT/MIT stands out with its high compatibility. It can stably coexist with chlorine and most cationic, anionic and nonionic surfactants. This property makes it widely used in water treatment, coatings, daily chemical products and other fields. In the water treatment industry, adding CMIT/MIT in appropriate amounts can effectively prevent pipes and equipment from being blocked and corroded due to microbial growth; in paint production, it can prevent the paint from deteriorating due to microbial contamination during storage and use. In addition, when used in higher doses, CMIT/MIT performs particularly well in biological sludge stripping, which can significantly improve the cleaning efficiency of industrial equipment and reduce maintenance costs, combining practical value with economic benefits.
1. CMIT/MIT has shown wide applicability in industrial and civilian fields, and can be regarded as a key agent for microbial control in multiple industries. In industrial circulating cooling water systems, it can effectively inhibit harmful microorganisms such as Legionella and iron bacteria that grow in high temperature and high humidity environments, prevent the formation of biological slime, and ensure the heat exchange efficiency of the system; in the oilfield wastewater treatment process, CMIT/MIT can kill sulfate-reducing bacteria in a targeted manner to avoid equipment corrosion and hydrogen sulfide gas production caused by microbial activities. In addition, in industries such as papermaking, pesticides, cutting oils, leather processing, detergents and cosmetics manufacturing, CMIT/MIT is used as a core preservative and bactericide. With its broad-spectrum antibacterial properties, it ensures that the product is free from microbial contamination during storage and use, and extends the shelf life.
2. In practical operation, the use of CMIT/MIT must strictly follow scientific standards. When used as a secondary biological sludge stripping agent, the recommended dosage concentration is 150-300mg/L, which can effectively disintegrate the biofilm structure, promote the sludge attached to the surface of the equipment to fall off, and restore the clean state of the pipeline and equipment; when used as a bactericide, the recommended concentration is controlled at 80-100mg/L, and it needs to be supplemented every 3-7 days to maintain a stable bactericidal effect in the system. It is worth emphasizing that CMIT/MIT cannot be used in combination with oxidizing bactericides because its non-oxidizing properties will antagonize oxidizing agents and weaken each other's effectiveness; at the same time, it is prohibited to use it in sulfur-containing cooling water because sulfur elements will react chemically with CMIT/MIT, causing the active ingredients to fail.
3. If CMIT/MIT is used in combination with quaternary ammonium salt compounds, the synergistic effect will significantly enhance the bactericidal performance. The cationic properties of quaternary ammonium salts can change the permeability of microbial cell membranes, making it easier for CMIT/MIT to penetrate cells, thereby improving the overall sterilization efficiency. In industrial sterilization scenarios, it is recommended that the addition ratio of CMIT/MIT be controlled at 0.05-0.4%. The specific dosage needs to be flexibly adjusted according to factors such as the degree of microbial contamination of the treatment medium, pH value and temperature, so as to achieve the best antibacterial effect and cost-effectiveness balance.
1. Water Treatment:
CMIT/MIT is commonly used in industrial cooling water systems, oilfield water injection, and wastewater treatment to prevent microbial-induced corrosion, biofouling, and slime formation.
2. Paints and Coatings:
It serves as a preservative in water-based paints, adhesives, and sealants to protect against microbial degradation and extend shelf life.
3. Paper and Pulp Industry:
Used to control microbial growth in paper mills, preventing slime formation and improving production efficiency.
4. Personal Care and Household Products:
Found in low concentrations in some shampoos, lotions, and cleaning products as a preservative (though its use in cosmetics is increasingly restricted due to safety concerns).
