MICROEMULSION COMPOSITIONS OF 3-ISOTHIAZOLONE COMPOUNDS.

摘要

A composition essentially free of organic solvents and having low VOC comprising (A) 2-n-octyl-3-isothiazolone as microbicidally active ingredient, (B) a surfactant system comprising (B1) an ethoxylated oil non-ionic surfactant and (B2) a sulfated or sulfonated oil anionic surfactant, the weight ratio of A:B being lower or equal to 50=50 and the weight ratio of B1:B2 being 20:80 to 70:30, optionally including 0 to 99.99 percent by weight water, said composition being in the form of a microemulsion concentrate or a microemulsion, said (A) being stable, and a method of protecting a locus using said composition.
