Oamiguard CMC: High-Performance CMIT/MIT-Based Antimicrobial Preservative for Industrial Water-Based Systems

Oamiguard CMC is a broad-spectrum preservative for the protection of industrial water-based products against spoilage from bacteria, yeasts, and fungi. It is a formulation of 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) and 2-methyl-4-isothiazolin-3-one (MIT) that has been specially formulated to provide good preservation at levels of 0.1% and below. The product is a light green clean liquid with an assay of ≥1.5% and a pH of 2.0–5.5 at 25°C. Our initial work indicates that Oamiguard CMC is effective in latices and polymer solutions, paints and stains, adhesives, aqueous mineral slurries, building materials, pigments, and pesticide formulations.

Product Data

Key Advantages

Broad-Spectrum Antimicrobial Protection
Oamiguard CMC is effective against a range of problem microorganisms. Selected MIC values from the TDS include 4 ppm against Alcaligenes faecalis, 5 ppm against Pseudomonas aeruginosa and Staphylococcus aureus, 12 ppm against Escherichia coli, 20 ppm against Penicillium funiculosum, 32 ppm against Rhodotorula rubra, and 65 ppm against Saccharomyces cerevisiae and Endomycopsis albicans. MIC values do not represent effective in-use concentrations and should be discussed with our technical representative.

Good Preservation at Low Use Levels
The product has been specially formulated to provide good preservation at levels of 0.1% and below. Results of initial studies indicate that a concentration of Oamiguard CMC in the range of 0.05–0.3% should be sufficient for most applications.

Practical Liquid Formulation
Oamiguard CMC is supplied as a light green clean liquid with an assay of ≥1.5% and a pH of 2.0–5.5 at 25°C, allowing convenient handling in water-based industrial formulations.

Broad Application Fit
Our initial work indicates effectiveness in latices and polymer solutions, paints and stains, adhesives, aqueous mineral slurries, building materials, pigments, and pesticide formulations.
