Rapidly-dissolving halogenated hydantoin powders having improved flow, reduced dust, improved wetability, and increased bulk densities.

摘要

A powdered halogenated hydantoin product having the following size distribution: (a) 70-100% halogenated hydantoin particles sized between 80 mesh and 200 mesh; (b) 0-20% particles sized larger than 80 mesh; and (c) 0-10% particles sized smaller than 200 mesh. The powdered product has superior dissolution and flow characteristics, while avoiding dusting where the product is used. Bromochlorodimethylhydantoin is the preferred halogenated hydantoin.
