What is Oamiguard BD20 Eco-friendly Preservative?

Oamiguard BD20 is a broad-spectrum, eco-friendly biocide preservative used to preserve industrial water-based products and prevent spoilage by bacteria, yeasts and fungi. It is an aqueous dispersion of 1,2-benzisothiazolin-3-one (BIT) with a non-specific mode of action, making bacterial resistance extremely unlikely.
