Isothiazolinones CAS 26172-55-4

What is Isothiazolinones CAS 26172-55-4?

Isothiazolinones CAS 26172-55-4 is a kind of water treatment agent with excellent performance and good miscibility. It can be miscible with various corrosion inhibitors, scale inhibitors and dispersants such as chlorine, and most anionic, cationic and non-ionic surfactants. The commodity in circulation on the market is usually a mixture composed of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI). At the same time, metal nitrite or metal nitrate will be added to improve stability and prevent decomposition, The mechanism of action of isothiazolinone is to kill bacteria by breaking the bonds between bacteria and algae proteins.

The core features of Isothiazolinones are fast sterilization speed, low dosage and broad antibacterial spectrum. It can effectively inhibit the reproduction of bacteria, fungi, algae and other microorganisms, and is widely used in industrial anti-corrosion, daily chemicals, water treatment and other fields.

应用

1. Industrial anti-corrosion field (core application scenarios) :

Water-based paint/ink anti-corrosion: Methylchloroisothiazolinone as tank preservatives, inhibition of coating, printing ink stored in the process of bacteria, mold, mildew prevent products, stink, viscosity changes (adding amount of 50-200 parts per million (PPM), suitable for interior wall paint, exterior wall paint, water-based wood coatings, etc.;

Adhesive/sealant anti-corrosion: Isothiazolinones is used in white latex, polyurethane adhesives, building sealants, etc., to prevent the decline in bonding strength, discoloration and odor caused by microbial contamination, and to extend the product’s shelf life.

Metalworking fluid anti-corrosion: Isothiazolinones, as a preservative for cutting fluids and coolants, inhibits the putrefaction substances (such as hydrogen sulfide) produced by bacterial reproduction, protects metalworking equipment from corrosion, and extends the service life of cutting fluids.

2. Daily chemicals and personal care field:

Cosmetic preservatives: Isothiazolinones are used in products such as shampoos, body washes, conditioners, face creams, and laundry detergents to inhibit microbial contamination (such as Escherichia coli and Staphylococcus aureus), and meet cosmetic preservative standards (the addition amount is usually ≤0.01%).

Wet wipes/hygiene products preservative: 5-Chloro-2-methyl-4-isothiazolin-3-one is used for disposable hygiene products such as wet wipes, diapers, and sanitary napkins. Isothiazolinones reduces the risk of bacterial infection during use through its bactericidal effect, ensuring the hygiene and safety of the products.

3. Water treatment field:

Industrial circulating water sterilization: 5-Chloro-2-methyl-4-isothiazolin-3-one is used in the circulating cooling water systems of power plants, chemical plants, steel mills, etc., to inhibit the reproduction of bacteria and algae, prevent scaling of pipelines and equipment and blockage by biological slime.

Wastewater treatment disinfection: Isothiazolinones, as an auxiliary disinfectant, are used for the terminal disinfection of industrial wastewater (such as printing and dyeing, papermaking wastewater) to reduce the microbial content in the effluent and meet the discharge standards (the dosage needs to be controlled to avoid residual toxicity).

4. Other special purposes:

Wood preservation: Isothiazolinones are used in the wood processing process to inhibit the growth of mold and decay fungi, and extend the service life of wood (such as outdoor landscape wood, construction wood).

Leather/textile preservation: Isothiazolinones are used in leather tanning and post-treatment of textile printing and dyeing to prevent mold and insect infestation during product storage.

Laboratory and medical consumables: Isothiazolinones are used as bacteriostatic agents for microbial culture media or for surface disinfection of medical consumables (such as disposable syringe packaging) (must meet medical-grade standards).
