product introduction

Oamiguard BD20 preservative is a broad-spectrum fungicide used to preserve industrial water-based products and prevent spoilage by bacteria, yeast, and fungi. It is a 20% aqueous dispersion of 1,2-benzisothiazolin-3-one in water. The product is effective against a range of problem microorganisms. Selected MIC examples from the TDS include 5 ppm against Alcaligenes faecalis, Bacillus subtilis, and Proteus vulgaris, and 40 ppm against Pseudomonas aeruginosa and Burkholderia cepacia. MIC values do not represent effective in-use concentrations and should be discussed with our technical representative.

Key Advantages

Broad-Spectrum Antimicrobial Preservation
Oamiguard BD20 is effective against a range of problem bacteria, yeast, and fungi. MIC data in the TDS provide a starting point for preservation evaluation, but in-use concentrations must be determined by application testing.
Good Formulation Compatibility
The product is compatible and effective over pH 4–12 and is stable in the presence of amines. It is incompatible with some oxidizing and reducing agents such as persalts and sulphites.
Heat-Stable and Non-Volatile Active
The active agents in Oamiguard BD20 are heat-stable and non-volatile. If the product is frozen, allow it to thaw and stir well before use.
Practical Recommended Use Level
Initial studies indicate that 0.05–0.3% Oamiguard BD20 should be sufficient for most applications. Because the effective concentration depends on the system, a testing programme is recommended to determine the most cost-effective dose.
Easy Handling
Oamiguard BD20 is supplied as a grey-white dispersion with a viscosity of 1200–3500 mPa·s at 25°C and a density of 1.05–1.10 g/mL, allowing convenient incorporation into liquid water-based formulations.

Applications

Synthetic polymer emulsions
Emulsion paints
Water-based adhesives
Household products
Tape joint compounds
Printing inks
Paper coating compositions
Metalworking fluids
Agricultural pesticide products
Aqueous mineral and pigment slurries

Sodium Pyrithione for Antimicrobial and Antifungal Protection

Sodium Pyrithione (NaPT; C5H4NOSNa), also known as Pyrithione Sodium, is an antimicrobial and antifungal compound supplied as a white to off-white powder or a stable 40% liquid solution, readily soluble in water and ethanol. It is effective against molds such as Aspergillus niger and bacteria such as E. coli, and is widely used in cosmetics, coatings, textiles, leather, water treatment, and marine antifouling as a preservative, bactericide, and dyeing auxiliary. Its broad-spectrum action involves chelating essential metal ions (e.g., Fe²⁺, Cu²⁺), disrupting microbial cell membranes, and inhibiting ATP synthesis. NaPT offers long-lasting protection, good thermal stability, and a relatively low environmental impact.
