Q1: What is the primary active ingredient in Nipacide BIT 20 DPG?
A: The active biocidal component is 1,2-benzisothiazolin-3-one (BIT), formulated as a 20% aqueous dispersion in dipropylene glycol (DPG) to enhance stability and compatibility in water-based systems.
Q2: In which types of industrial formulations is Nipacide BIT 20 DPG typically used?
A: It is widely applied in water-based paints and coatings, adhesives, sealants, construction chemicals, metalworking fluids, and household & institutional cleaning products where broad-spectrum fungicidal and bacteriostatic protection is required during storage and in-service use.
Q3: How does the DPG carrier affect formulation compatibility and performance?
A: Dipropylene glycol serves as a stabilizing co-solvent that improves dispersion homogeneity, reduces volatility compared to low-boiling carriers, and enhances compatibility with polar and semi-polar matrices—supporting consistent antimicrobial efficacy without compromising formulation rheology or clarity.
Q4: Is Nipacide BIT 20 DPG suitable for use in products intended for direct food contact applications?
A: Nipacide BIT 20 DPG is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for preservation of non-food industrial and consumer products; any use in food-related environments must be evaluated separately against applicable local regulations and migration requirements.
Q5: What are key handling and stability considerations for this product?
A: Store in tightly sealed containers at temperatures between 5–30 °C, away from strong oxidizing agents and alkaline materials. The dispersion is stable under recommended conditions but may separate upon prolonged storage—gentle agitation before use restores uniformity. Avoid freezing, as it may irreversibly affect physical stability.
