Industrial preservatives BIT (1,2-benzisothiazolin-3-one)
1,2-Benzisothiazolin-3-one English abbreviation BIT, CAS#2634-33-5, BIT antiseptic fungicide is a new generation of long-acting fungicide without CIT/MIT and AOX, Dalian Tianwei Chemical Co., Ltd. has specially developed a variety of products and formula products for different forms based on BIT active substances, such as: 3Q-BIT10, 3Q-BIT20, 3Q-MB5, etc. Wide range of applications, such as: petroleum water emulsions, latexes, latex paints, finishes including varnishes, waxes and colorants, water-based adhesives, inks, casein, dispersed rosin, textiles, spin finishes, pesticide formulations , mud, white powder, tape joint compound, leather processing solution and other water-based systems and sterilization and preservative of fresh animal hides and shells.
advantage
High-efficiency, low-toxicity, broad-spectrum industrial antibacterial and antifungal agent, can obtain good antibacterial properties in a very small amount, and can effectively kill various microorganisms, such as bacteria, molds, yeasts and sulfate reducing bacteria (SRB) All are effective, especially for Gram-negative bacilli.
It is a low toxicity compound. The oral LD50 of rats is 1400mg/kg, and no carcinogenicity, teratogenicity and mutagenicity have been found. It is irritating to the skin.
Good solubility, miscible with water and some organic solvents, stable to amine compounds. .
Excellent chemical stability, no additional stabilizers are required, and the bactericidal efficacy remains unchanged in a wide pH range (4 to 12) and at a high temperature of 150 °C. Does not burn and is easy to transport.
When there are organic substances, non-ionic, anionic and cationic surfactants in the system, the bacteriostatic effect will not be affected. And it has a long-term protective effect on the anti-corrosion material system.
It is easy to use, can be added directly without special equipment in production, does not cause pollution, does not corrode metals, has a half-life in soil of less than 24 hours, and will not accumulate in aquatic organisms.
The active substances of BIT have been widely used in marine anti-fouling, anti-corrosion and mildew prevention of various industrial products, agriculture and forestry environmental protection and other fields by developed countries such as Europe, America and Japan. Drug Administration) certification.
No release of formaldehyde, no halogen, no volatility, no heavy metals, low odor, no foaming, no adverse effects on the added system (such as color, taste, etc.), and can prevent sludge formation.
The antibacterial mechanism is: by destroying the permeability of the cell membrane, affecting the activity of related enzymes on the membrane and in the cell, causing the integrity of the cell wall to be destroyed or affecting the metabolic activity of the cell, thereby playing a bactericidal effect. There is no specific mode of action, which suggests that bacterial antibodies are unlikely to be produced.
BIT has the advantage of little damage to enzyme preparations, and can be used in enzyme-added laundry detergents for long-term preservatives
