4,5-Dichloro-2-n-octylisothiazolinone: A Powerful Biocide for Industrial Applications

In the world of industrial chemicals, biocides play a crucial role in preventing the growth of harmful microorganisms in various products and processes. One such biocide that has gained popularity in recent years is 4,5-Dichloro-2-n-octylisothiazolinone (DCOIT), a potent antimicrobial agent that is widely used in paints, coatings, adhesives, and other industrial applications.

Manufactured and supplied by INNO Specialty Chemicals, DCOIT is a member of the isothiazolinone family of biocides, which are known for their broad-spectrum activity against bacteria, fungi, and algae. DCOIT, in particular, has been found to be highly effective against marine fouling organisms, making it a popular choice for marine coatings and antifouling paints.

In this article, we will explore the properties, benefits, and applications of DCOIT in more detail, and examine why it has become such a popular biocide for industrial use.

Properties of DCOIT

DCOIT is a white to pale yellow crystalline powder with a molecular formula of C11H17Cl2NOS. It has a molecular weight of 284.23 g/mol and a melting point of 47-50°C. DCOIT is soluble in organic solvents such as acetone, ethanol, and chloroform, but is insoluble in water.

One of the key properties of DCOIT is its high stability and persistence in the environment. It has a relatively long half-life and can remain active for several months, making it an ideal biocide for long-term protection against microbial growth.

Benefits of DCOIT

DCOIT offers several benefits as a biocide for industrial applications. Some of the key advantages include:

1. Broad-spectrum activity: DCOIT has been shown to be effective against a wide range of bacteria, fungi, and algae, making it a versatile biocide for a variety of applications.

2. Low toxicity: DCOIT has low toxicity to humans and animals, and is considered to be a safer alternative to other biocides such as tributyltin (TBT) and copper-based compounds.

3. Long-lasting protection: DCOIT has a high persistence in the environment, providing long-lasting protection against microbial growth.

4. Cost-effective: DCOIT is a cost-effective biocide compared to other alternatives, making it an attractive option for industrial users.

Applications of DCOIT

DCOIT is used in a variety of industrial applications, including:

1. Marine coatings: DCOIT is widely used in antifouling paints and coatings for boats, ships, and other marine structures. Its high efficacy against marine fouling organisms such as barnacles, algae, and mussels makes it an ideal choice for long-term protection against biofouling.

2. Paints and coatings: DCOIT is also used in paints and coatings for buildings, bridges, and other structures to prevent microbial growth and degradation.

3. Adhesives: DCOIT is used in adhesives to prevent microbial growth and contamination during storage and use.

4. Textiles: DCOIT is used in textiles to prevent fungal and bacterial growth, and to improve the durability and longevity of the fabric.

Conclusion

In conclusion, DCOIT is a powerful biocide that offers broad-spectrum activity, low toxicity, long-lasting protection, and cost-effectiveness for a range of industrial applications. As a leading manufacturer and supplier of DCOIT, INNO Specialty Chemicals is committed to providing high-quality and reliable solutions for microbial control in industrial settings.
