  • Synergistic microbicidal compositions
    Patent number: 8138212
    Abstract: This invention relates to synergistic combinations of selected isothiazolin-3-one microbicides in combination with a second microbicide or formulation ingredient or raw material. The combinations have greater efficacy than would be expected from combinations of the individual components. The combinations include mixtures of (a) Methyl-4-isothiazolin-3-one or (b) 1,2-Benzisothiazolin-3-one with one or more of a variety of other compounds.
    Type: Grant

  • Microbicidal composition
    Patent number: 7468384
    Abstract: A microbicidal composition of 1,2-benzisothiazolin-3-one; and at least one of benzalkonium chloride, benzethonium chloride, benzyl alcohol, caprylyl glycol, chlorphenesin, diazolidinyl urea, ethylparaben, imidazolidinyl urea, methylparaben, phenoxyethanol, linoleamidopropyl PG-dimonium chloride phosphate, cocamidopropyl PG-dimonium chloride phosphate, propylparaben, cis-1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride, dehydroacetic acid or its salts, benzoic acid or its salts, and sodium hydroxymethylglycinate.
    Type: Grant
    Filed: November 2, 2005
    Date of Patent: December 23, 2008
    Assignee: Rohm and Haas Company
    Inventors: Richard Levy, Megan Anne Diehl, Dolores Ann Shaw, Eileen Fleck Warwick
  • Microbicidal composition
    Patent number: 6511673
    Abstract: Microbicidal compositions containing selected ratios of a non-halogenated 2-alkyl-3-isothiazolone and one or more (C1-C7) esters of para-hydroxybenzoic acid are disclosed as improved formulations for controlling microbial growth. In particular the combination of 2-methyl-3-isothiazolone with a mixture of methyl para-hydroxybenzoate and propyl para-hydroxybenzoate is especially effective as a microbicidal component in personal care compositions.
