Abstract:
This invention provides a process of making a stable aqueous dispersion including concentrated, finely divided particles of a water insoluble biocide active, which comprises grinding the biocide in water in the presence of a non-ionic polymeric dispersant and optionally a co-dispersant, and compositions prepared by this process.
Abstract:
What is described herein is an environment-friendly, biodegradable, non-corrosive aqueous solution of isothiazolin-3-one comprising: (i) at least about 5 wt. % to about 50 wt. % of 1,2-benzisothiazolin-3-one (BIT); (ii) about 5 wt. % to 15 wt. % of neutralizing agent; (iii) about 0.01 wt. % to about 20 wt. % of at least one biodegradable chelating agent; (iv) about 0.01 wt. % to about 20 wt. % of at least one alkyl polyglucoside, a solubilizer; (v) about 0.1 wt. % to about 2.0 wt. % of polyvinyl alcohol (PVA), a crystal modifier; and (vi) about 50% to about 85% by wt. of water; and wherein said aqueous solution is free from volatile organic compounds (VOC's), glycerols, polyglycerols, derivatives of glycerols, glycols, polyglycols and/or derivatives of glycols, and wherein, the frozen aqueous solution of isothiazolin-3-one is capable of completely thawing within two hours at room temperature or at about 25° C. to about 30° C.
