    According to our (Global Info Research) latest study, the global Isothiazolinone API market size was valued at US$ 326 million in 2025 and is forecast to a readjusted size of US$ 415 million by 2032 with a CAGR of 3.6% during review period.
    Isothiazolinone is an excellent water treatment agent with excellent compatibility with various corrosion inhibitors, such as chlorine, scale inhibitors and dispersants, and most anionic, cationic, and nonionic surfactants. Commercially available products are typically mixtures of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI). Metal nitrites or nitrates are also added to enhance stability and prevent decomposition. Isothiazolinone acts by breaking bonds between bacterial and algal proteins, rapidly and irreversibly inhibiting their growth upon contact, leading to cell death. It exhibits strong inhibitory and bactericidal effects against common bacteria (sulfate-reducing bacteria and sludge-forming bacteria), fungi (iron-oxidizing bacteria, molds, yeasts), and algae. It boasts high bactericidal efficiency, good degradability, no residue, safe operation, excellent compatibility, strong stability, and low cost of use. At high doses, it is significantly effective in removing biosludge and is currently widely used in steelmaking, oilfield water injection, thermal power generation, papermaking, oil refining, chemicals, textiles, industrial cleaning, pesticides, cutting oils, water-based coatings, daily chemicals, inks, dyes, and leather tanning. This report studies isothiazolinone API market, defined as follows: CIT/MIT technicals (CIT/MIT with an active ingredient content ≥14%); MIT technicals (MIT with an active ingredient content ≥50%).
    In 2024, global Isothiazolinone API sales reached approximately 142,560 tons, with an average global market price of around US$ 2,005 per ton.
    The market driver of isothiazolinone API is primarily fueled by its broad-spectrum antimicrobial efficacy, which makes it a critical raw material in pharmaceuticals, personal care products, and industrial biocides.
