  • Rapidly-dissolving halogenated hydantoin powders having improved flow, reduced dust, improved wetability, and increased bulk densities
    Patent number: 6706395
    Abstract: 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.
    Type: Grant

  • Aqueous suspensions of low solubility and low stability water additives
    Patent number: 6281169
    Abstract: A method of improving the rate of dissolution in water of low solubility compounds by combining a low solubility compound with a rheology additive that is made of platelets or particles which orient together with ionic or hydrogen bonds. The inventive method also may improve the hydrolytic stability of hydraulically unstable low solubility compounds.
