For procurement managers in the chemical industry, selecting the right biocide is paramount for maintaining product integrity and operational efficiency. One of the most effective and widely used biocidal active substances is the CMIT/MIT blend, particularly in its 14% concentration. Understanding its properties and sourcing effectively can significantly impact cost and performance.

What is CMIT/MIT 14%?

CMIT/MIT 14% refers to a liquid formulation containing a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and 2-methyl-4-isothiazolin-3-one (MIT). This combination provides a broad spectrum of antimicrobial activity, making it highly effective against bacteria, fungi, and algae at relatively low concentrations. Its efficacy stems from its ability to disrupt essential cellular processes within microorganisms.

Key Applications for Procurement

As a procurement specialist, you'll find CMIT/MIT 14% to be an indispensable component in various sectors. Its primary applications include:

  • Industrial Water Treatment: This is a major use case, where CMIT/MIT 14% serves as a potent biocide to prevent the growth of slime, algae, and bacteria in cooling towers, process water, and wastewater treatment systems. Its presence helps maintain system efficiency and prevent costly downtime.
  • Cosmetics and Personal Care: As a preservative, it safeguards formulations like shampoos, lotions, and conditioners from microbial contamination, extending shelf life and ensuring consumer safety. However, due to potential sensitization, regulatory limits are strictly observed.
  • Papermaking: In paper mills, CMIT/MIT 14% is used to control microbial growth in process water and pulp, preventing slime formation that can degrade paper quality and damage equipment.
  • Oilfield Operations: It functions as an effective oilfield bactericide, particularly in controlling sulfate-reducing bacteria (SRB) in injection water and production fluids, thereby preventing corrosion and reservoir souring.
  • Paints, Coatings, and Adhesives: It acts as an in-can preservative, preventing spoilage and maintaining the quality of water-based paints, coatings, and adhesives during storage.

Procurement Considerations: What to Look For

When you are ready to buy CMIT/MIT 14%, several factors are crucial to ensure you are sourcing from a reliable manufacturer:

  • Product Specifications: Always request a detailed Certificate of Analysis (CoA) that includes active content (14-15%), pH range (2.0-4.0), and density. Ensure the CMIT:MIT ratio is within the specified range for optimal performance.
  • CAS Number: Verify the CAS numbers: 26172-55-4 for CMIT and 2682-20-4 for MIT.
  • Purity and Stability: High-quality manufacturers will guarantee product stability and consistent purity. Avoid products that are unstable or have a short shelf life.
  • Supplier Reputation: Partner with manufacturers that have a proven track record, robust quality control systems, and offer competitive CMIT/MIT 14% prices. Seeking quotes from multiple suppliers in China is a good starting point.
  • Regulatory Compliance: Ensure the product meets relevant regional and international regulatory standards, especially for cosmetic applications.

Sourcing CMIT/MIT 14% in China

China has emerged as a significant global supplier of industrial chemicals. When looking to purchase CMIT/MIT 14%, focusing on established chemical manufacturers can yield significant cost savings without compromising quality. These manufacturers often have extensive production capacities and streamlined logistics, ensuring a stable supply chain. Engaging with them directly for CMIT/MIT 14% price inquiries can provide valuable insights into market pricing and available quantities.

In conclusion, CMIT/MIT 14% is a versatile and powerful biocide essential for many industrial applications. By understanding its properties and prioritizing reputable manufacturers and suppliers, procurement professionals can secure a consistent and cost-effective supply of this critical chemical, ensuring operational success and product quality.
