Abstract
Abstract The invention provides certain N-thio substituted isothiazolin-3-one compounds and process for their manufacture, and includes their use in protecting media which are susceptible to infection by micro-organisms against such infection and the suppression of infection in media already infected. These compounds provide a quicker kill of micro-organisms than the parent isothiazolin-3-ones.
