Overview

Powerful diesel biocide combining CMIT/MIT actives for long-term microbial protection. Keeps diesel clean, prevents filter clogging, and protects tanks from corrosion.

Product description

RXSOL CMIT/MIT Diesel Biocide is a broad-spectrum antimicrobial formulation designed to prevent and control microbial contamination in diesel fuels, kerosene, and storage tanks. The synergistic blend of CMIT/MIT effectively targets bacteria, fungi, and yeasts responsible for sludge formation, corrosion, filter plugging, and fuel degradation.

Glycol acts as a stabilizing solvent, ensuring uniform dispersion and compatibility across various hydrocarbon and aqueous phases.

Applications

Wide range of application of Diesel Biocide CMIT MIT

  • Diesel storage tanks (marine, automotive, generator, bulk fuel)
  • Fuel distribution systems and pipelines
  • Oil refineries and fuel terminals
  • Marine vessels and standby generator tanks
  • Biofuel blends and fuel-water separation systems

Where it is used

Broad-Spectrum Antimicrobial Activity
CMIT/MIT are effective against a wide range of microorganisms, including bacteria, fungi, molds, and yeasts. This ensures total protection of diesel fuel and storage systems from microbial contamination.
 
Fast and Long-Lasting Action
CMIT/MIT exhibits rapid microbial kill rates even at low concentrations, followed by residual protection that keeps the system sterile for extended periods, reducing the need for frequent dosing.
 
Dual-Phase Effectiveness
Unlike many traditional biocides, isothiazolinones are active in both fuel and water phases. This is crucial since microbial growth often occurs at the fuel–water interface inside storage tanks.
 
Prevents Sludge and Filter Clogging
By eliminating microbial colonies, CMIT/MIT prevents the formation of biofilms, black sludge, and filter blockages, maintaining smooth fuel flow and reducing maintenance costs.
 
Corrosion Prevention
Microbial activity often leads to microbiologically induced corrosion (MIC). Isothiazolinones prevent this by stopping the metabolic processes of sulfate-reducing bacteria (SRB), which are the main cause of pitting and rusting in fuel tanks.
 
Fuel Compatibility
CMIT/MIT formulations (especially when blended in dipropylene glycol) are fully soluble and compatible with diesel, biodiesel, and kerosene fuels, without affecting fuel quality or engine performance.
 
High Stability and Shelf Life
Isothiazolinones are chemically stable under a wide range of temperatures and pH, ensuring consistent performance during long-term storage of both the biocide and the treated fuel.
 
Low Required Dosage
Due to their high potency, CMIT/MIT-based biocides are effective at very low concentrations (typically 100–500 ppm), making them cost-effective and efficient for industrial-scale applications.
 
Environmentally Manageable Profile
Modern CMIT/MIT formulations degrade over time into non-persistent by-products, minimizing long-term environmental impact when used responsibly according to recommended dosage.
 
Synergistic Performance
The combination of CMIT and MIT provides enhanced antimicrobial synergy, ensuring faster kill rates and a wider range of protection compared to single-component systems.
