ANTIMICROBIAL MIXTURES OF 1,3-BIS(HYDROXYMETHYL)-5,5-DIMETHYLHYDANTOIN AND 1,2-BENZISOTHIAZOLIN-3-ONE

摘要

This invention is directed to a broad spectrum antimicrobial composition which comprises a mixture of 1,2-benzisothiazolin-3-one, or a salt thereof, (BIT) and 1,3-bis(hydroxymethyl)-5,5-dimethylhydantoin (DMH), said mixture provided in an amount to protect a substrate from attack by one or more bacterial organisms. The composition can be used broadly in industrial systems and more particularly with substrates such as paints, coatings, stucco, concrete, stone, cementaceous surfaces, wood, caulking, sealants, textiles, leather, wood, preservatives, metal working fluids, drilling muds, clay slurries, glazes, optical brightness, carpet backing, pigments and as a preservative for other aqueous and wet state products, and the like.
