  • Water-based microbicide formulation
    Patent number: 3996378
    Abstract: Products and processes of a water-based formulation of methylene bis thiocyanate (MBT) in a xanthan gel, which is a hydrophilic colloid in water where the colloid is utilized at a concentration of about 0.02-2.0 weight percent and preferably 0.1-1.0 of the colloid carrier. In use in water treatment, this dosage is adjusted so that use dosage contains about 2-1000 ppm by weight of the microbicide and preferably 20-200 ppm. Alternatively, a ternary formulation may be used containing methylene bis thiocyanate plus an auxiliary fast-acting biocide in the same xanthan gel. The auxiliary microbicide is selected from an n-alkyl (C.sub.12 -C.sub.18) dimethyl(benzyl)ammonium chloride such as the preferred quaternary; i.e., tetradecyl benzyl dimethyl ammonium chloride (ROCCAL-MC-14--Hilton-Davis).
