Isothiazolinones: a rising star in the field of preservatives
Isothiazolinones are mainly composed of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI). Isothiazolinones kill by breaking the bonds between bacterial and algal proteins. After contact with microorganisms, it can rapidly and irreversibly inhibit their growth, resulting in the death of microbial cells, so it has a strong inhibition and killing effect on common bacteria, fungi, algae and so on. Isothiazolinone has the advantages of high killing efficiency, good degradation, no residue, safe operation, good compatibility, strong stability and low cost. It is miscible with chlorine and most negative, cationic and non-ionic surfactants. At high dose, it has remarkable effect on biological slime stripping
Basic characteristic
Isothiazolinones are known for their efficient, broad-spectrum bactericidal properties. They have a very strong control and killing effect on various bacteria, fungi, algae and molds. This bactericidal effect mainly relies on its ability to break the bonds between bacterial and algal proteins, thereby damaging the cell structure of the microorganism and making it lose its ability to replicate and grow.
Fields and applications
Fields and applications
Cosmetics and personal care products
Due to its low toxicity and good compatibility, isothiazolinone is widely used in cosmetics and personal care products, such as shampoo, conditioner, facial cleanser, face cream, etc. It can effectively inhibit the growth of microorganisms and maintain the stability and safety of the product.
Coatings and water-based polymers
In coatings and water-based polymers, isothiazolinone acts as a preservative to prevent the growth of microorganisms and extend the service life of the product. At the same time, it will not have adverse reactions with other components in the paint, keeping the performance of the paint stable.
Industrial circulating water and water treatment
Isothiazolinones also play an important role in the field of industrial recycled water and water treatment. It can control the growth of bacteria, algae and other microorganisms in water to ensure the stability and safety of water quality. Especially in swimming pools, water parks and other places, the addition of isothiazolinone can significantly improve the safety of water quality.
Other fields
In addition, isothiazolinone is also widely used in papermaking, adhesives, inks, dyes, paraffin, wood, leather and other industries, as a bactericidal preservative.
Environmental performance
Environmental performance
Isothiazolinone will not produce toxic and harmful substances after natural degradation, no pollution to the environment. This feature makes it have greater application advantages in today's increasingly stringent environmental requirements. At the same time, it does not affect water quality, and can be used in situations where water resources need to be protected.
Market prospect
Market prospect
With the increasing attention to product quality and safety, isothiazolinone as a high-efficiency, low-toxicity preservative, its market demand continues to rise. Especially in cosmetics, coatings, water treatment and other fields, isothiazolinones have broad application prospects.
