What is OIT Biocide?

Industrial-grade Octyl Isothiazolinone (OIT), as an oil-soluble bactericidal and preservative agent, has a wide range of applications in various industrial fields. The following is a detailed introduction:

I. Basic Information

Chinese Name: Octyl Isothiazolinone

English Name: 2-Octyl-2H-isothiazol-3-one

Abbreviation: OIT

Chemical Name: N-Octyl-4-isothiazolin-3-one

Molecular Formula: C11H19NOS

Relative Molecular Mass: 213.34

CAS Number: 26530-20-1

II. Product Features

1. Broad-spectrum antibacterial: Octyl isothiazolinone has excellent inhibitory effects on various microorganisms such as fungi, bacteria, molds, and enzymes.

2. Low toxicity and long-lasting effect: This product is formaldehyde-free, odorless, and has a long-lasting antibacterial effect.

3. Strong bactericidal power: Its ability to kill mold is powerful, and its effect is significantly better than traditional mildew inhibitors, making it a replacement product for traditional mildew inhibitors.

4. Environmentally friendly: Octyl isothiazolinone can naturally degrade into non-toxic substances and does not cause environmental pollution.

III. Preparation Method

The preparation of OIT Biocide is mainly through chemical synthesis, including the reaction of methyl acrylate with sodium hydrosulfide or sodium disulfide, and subsequent reaction steps with n-octylamine and chlorine. The specific process may vary depending on the process, but generally, it requires controlling reaction conditions and purifying the product to obtain high-quality octyl isothiazolinone.

IV. Product Uses

Octyl isothiazolinone can be widely used in the following fields:

1. Coatings and paints: As an antiseptic and mildew inhibitor, it improves the durability and service life of coatings.

2. Inks: Prevents ink from mildewing and deteriorating during storage and use.

3. Lubricating oils: Protects lubricating oils from microbial contamination and extends their service life.

4. Shoe polish and leather chemicals: Maintains the cleanliness and mildew resistance of leather products.

5. Wood products: Prevents wood products from becoming damp and moldy, maintaining their appearance and durability. 6. Cultural Relics Protection: Used to protect cultural relics from microbial erosion.

V. Storage and Preservation

1. Packaging: Usually packaged in 25 kg drums.

2. Storage Conditions: Store in a cool, well-ventilated place away from light. The storage temperature should be below 40°C to ensure product stability and effectiveness.

3. Shelf Life: Generally 12 months, but the specific duration may vary depending on the product batch and storage conditions.

4. Safety Precautions: Octyl isothiazolinone is a Class II corrosive chemical. Protective glasses and acid-resistant gloves should be worn during use. If it comes into contact with skin, rinse immediately with plenty of water.

In summary, OIT Biocide is an excellent oil-soluble bactericidal and preservative agent with broad-spectrum antibacterial properties, low toxicity, long-lasting effect, strong bactericidal power, and environmental friendliness. It plays an important role in various industrial applications.
