Shandong Kairui Chemical Co., Ltd. was established on November 27, 2015. It is located in Xuecheng Chemical Industrial Park, Zaozhuang City, Shandong Province. It is an environment - friendly enterprise that integrates the research and development, production, and sales of comprehensive high - end fine chemicals, including water treatment agents, textile printing and dyeing auxiliaries, paper - making auxiliaries, oil - field auxiliaries, water - based coating auxiliaries, concrete admixtures, daily - use cleaning and disinfection auxiliaries, and electronic product cleaners. It has built a modern production plant with an annual output of 280,000 tons of various monomer auxiliaries, such as organic phosphorus, polymers, and bactericides. As a manufacturer of isothiazolinone, Kairui Chemical has rich experience, advanced equipment, and stable product quality. Its isothiazolinone products, together with benzalkonium chloride, 1,2 - benzisothiazolin - 3 - one, and other bactericidal products, are widely used in various industries.

Isothiazolinone is a kind of organic compound with broad - spectrum antibacterial activity, and it is mainly used in the following aspects: - **Antibacterial and preservative in industrial water treatment**: It can effectively inhibit the growth of various bacteria, fungi, and algae in industrial circulating water, cooling water, and wastewater treatment systas. This helps prevent the formation of biofilms and slime, reduces equipment corrosion and blockage, and improves the efficiency and service life of the water treatment systa. - **Preservative in cosmetics and personal care products**: It is added to cosmetics, shampoos, lotions, and other products as a preservative to prevent the growth of microorganisms and extend the shelf life of the products. However, due to its potential allergenicity, its use in cosmetics is strictly regulated in some countries and regions. -

Isothiazolinone is a common preservative and antimicrobial agent, and products containing it include the following categories: -

Cosmetics and personal care products

: Foundations, concealers, bronzers, self - tanners, eye shadows, mascaras, make - up raovers, moisturizers, sunscreens, shampoos, conditioners, bubble baths, soaps, baby wipes, creams, lotions, and gels. -

Isothiazolinones  is toxic. - **Toxicity to humans**: Isothiazolinone can cause skin irritation, allergic contact dermatitis, and eye irritation in humans. Inhalation or ingestion of high concentrations of isothiazolinone may also affect the respiratory system, gastrointestinal tract, and central nervous system, leading to symptoms such as coughing, shortness of breath, nausea, vomiting, and dizziness. - **Toxicity to the environment**: It is toxic to aquatic organisms and can have a negative impact on the ecological environment. It may cause harm to fish, invertebrates, and other aquatic life, and affect the balance of the aquatic ecosystem. However, when used properly and in accordance with relevant regulations and safety guidelines, the potential risks of isothiazolinone can be effectively controlled. In industrial applications, appropriate protective measures and safety procedures are usually required to ensure the safety of workers and the environment.

When we turn on the faucet, we expect clear, pure water that brings comfort and peace of mind to our lives. But the reality is often not as expected, the impurities in the water, odor, and even potentially harmful substances, quietly affecting our water experience and health.

In the huge system of industrial production, the industrial circulating water system is like a continuously beating “heart”, conveying a constant flow of power for each link. However, do you know, scale, corrosion and microbial growth of these “invisible killers”, is always threatening the health and life of the circulating water system?

• Water treatment field: In industrial circulating cooling water systems, boiler water systems, oilfield reinjection water systems, etc., it can prevent the dissolved salts in the water from scaling on the surface of equipment and pipelines, reduce the heat exchange efficiency, reduce equipment corrosion, prolong the service life of the equipment, and ensure the normal operation of the system.
• Petroleum industry: It is used for scale inhibition in oilfields to prevent blockage and corrosion problems caused by the deposition of salts such as calcium, magnesium, and barium in oil wells, oil pipelines, and water injection systems, ensuring the smooth progress of the oil extraction and transportation processes, and improving the productivity of oil wells and the efficiency of water injection.
• Detergent industry: As a washing aid, it can chelate metal ions in water, prevent the reaction between metal ions and the active ingredients in the detergent, improve the decontamination ability and cleaning effect of the detergent. At the same time, it can also prevent fabrics from yellowing or discoloring due to the presence of metal ions during the washing process.
• Other fields: It can be used as a stabilizer for peroxide bleaching. In the bleaching processes of industries such as textiles and papermaking, it can effectively inhibit the decomposition of peroxides and improve the bleaching effect and product quality. It can also be used in industries such as municipal industrial cleaning water, geothermal water treatment, papermaking, electroplating, metal pickling, and cosmetics, playing roles such as scale inhibition, chelation, and stabilization
