COMPOSITION

摘要

S 35309 COMPOSITION A particulate composition comprising an isothiazolinone or isothiazolothione or a salt or complex thereof and a water soluble metal salt. The salt is typically a metal salt, for example the sodium salt of 1,2-benzisothiazolin-3-one and the water soluble metal salt is particularly an alkali metal salt such as disodium hydrogen phosphate. A preferred composition can be obtained by stirring together an isothiazolinone or isothiazolothione, a base and an alkali metal phosphate in the presence of water until a dry particulate product is obtained. The particulate product is typically highly and rapidly soluble in water and may be stored in a container formed from a water soluble material, for example a bag formed from polyvinyl alcohol.
