BIT Preservative – Technical & Application Guide

Benzisothiazolinone (BIT), also known as 1,2-benzisothiazolin-3-one, is a broad-spectrum industrial preservative and biocide widely used to protect water-based formulations against bacterial and fungal contamination. It is commonly classified as an industrial preservative for material protection.

BIT preservative is commonly used in water-based adhesives, paints and coatings, sealants, polymer emulsions, construction chemicals, and industrial detergents to prevent microbial growth during storage and use, especially in water-based adhesive systems.

Yes. BIT is specifically designed for water-based systems and shows excellent stability and antimicrobial performance in aqueous formulations across a wide pH range, making it suitable for paints and coatings applications.

The typical dosage of BIT preservative ranges from 0.05% to 0.3%, depending on the formulation type, microbial challenge level, and regulatory requirements. Detailed technical parameters can be found on the BIT preservative product page.

BIT usage is permitted in many industrial applications. However, its use may be restricted or prohibited in certain personal care or cosmetic applications depending on regional regulations. For cosmetic use, alternative cosmetic preservatives are often recommended.

BIT offers better stability in alkaline conditions and is commonly used in industrial applications, while MIT is more frequently applied in cosmetics and personal care formulations. A detailed comparison can be found on the MIT preservative page.

Yes. BIT shows excellent compatibility with water-based adhesives, coatings, and sealants, making it a preferred preservative for these industries, particularly in adhesives and sealants formulations.

BIT preservative should be stored in a tightly closed container, in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible materials. Storage guidance is also outlined in the safety and handling guidelines.
