  • Process for making antimicrobial agents in aqueous dispersion form containing 2-(4- thiazolyl)-benzimidazole alone or in combination with 1,2-dibromo-2,4-dicyanobutane
    Publication number: 20020106391
    Abstract: Aqueous dispersions of 2-(4-thiazolyl)-benzimidazole (TBZ), alone or in combination with 1,2-dibromo-2,4-dicyanobutane (DBDCB), and processes for making the same, are disclosed. These processes generally comprise mixing a xanthan gum with water, adding TBZ and mixing until uniform. DBDCB dispersions are prepared by mixing xanthan gum with water, adding DBDCB, maintaining the mixture at a temperature below about 40° C., grinding the mixture and mixing until uniform. The TBZ and DBDCB dispersions are then blended to prepare a dispersion containing both active ingredients. A method for inhibiting microbial growth utilizing these dispersions is also claimed.
