Aqueous solutions of 1,2-benzisothiazolin-3-one

Abstract

What is described herein is an environment-friendly, highly aqueous solution of 1, 2-benzisothiazolin-3-one (BIT) which is free from volatile organic compounds (VOC), glycols, derivatives of glycols, glycerols and / or derivatives of glycerols. The composition comprises: (i) about 0.1 % to about 30% by wt. of BIT; (ii) about 5% to about 15% by wt. of neutralizing agent; (iii) about 50% to about 85% by wt. of water; and (iv) about 0.1% to about 5% by wt. of chelating agent. The aqueous solution of BIT may further comprise at least one water soluble form of a co-biocide. The composition is efficient in protecting aqueous media against microbial attack in various industrial applications.

Description

technical field [0001] The present invention relates to aqueous solutions of biocidal compositions, more particularly to clear aqueous solutions of 1,2-benzisothiazolin-3-one (BIT), free of volatile organic compounds (VOCs), glycerol, Glycerol derivatives, glycols and / or glycol derivatives. Background technique [0002] 1,2-Benzisothiazolin-3-one (hereinafter referred to as BIT) is a well-known industrial biocide that effectively protects aqueous media from microbial attack. It is effective as a biocide and is suitable for a variety of industrial applications such as metalworking fluids, cooling tower water, emulsions, plastic films, paints, building materials, stucco, concrete, caulks, sealants, joints, adhesives , Leather, Wood, Inks, Pigment Dispersions, Drilling Slurries, Clay Slurries, Agricultural Applications, Seed Coatings, Pesticide Compositions, Cosmetics, Household Products, Cleaning, Disinfection, Enzyme Formulations, Laundry Products, etc. [0003] It is advan...
