  • Patent number: 5078896
    Abstract: The invention relates to an aqueous composition incorporating quaternary ammonium salt or amine oxide surfactant and cumene sulphonate, xylene sulphonate, toluene sulphonate or mixtures thereof and displaying pronounced shear thinning behavior, i.e., exhibiting high viscosities at low rates of shear and intended to be applied to non-horizontal structural surfaces.The compositions contain acid and hydrogen peroxide or peracetic acid as active ingredients.The invention also relates to thickening compositions, containing abovementioned nitrogen containing surfactant and the sulphonate and to processes of cleaning non-horizontal surfaces.

  • Patent number: 5041239
    Abstract: A premix composition suitable for the preparation of thicknened aqueous compositions by dilution with water, containing (i) an amine, selected from the group consisting of primary amines, secondary amines, tertiary amines, diamines, and amines in the form of a heterocyclic ring, wherein the primary, secondary, tertiary amines, and diamines carry at least one nitrogen linked hydrocarbon group which represents a saturated or unsaturated linear or branched alkyl group having at least 10 carbon atoms or an aryl, aralkyl or alkaryl containing up to 24 carbon atoms, and wherein the other nitrogen linked groups may be different or the same and represents hydrogen, substituted or unsubstituted alkyl groups, aryl groups, aralkyl groups or polyalkoxy groups containing 1-3 alkoxy groups, or wherein when the amine selected is in the form of a heterocyclic ring, it contains at least two nitrogen atoms, one of which being substituted by amino (lower) alkyl or hydroxy (lower) alkyl, which optionally is reacted with fatty ac

  • Patent number: 4853146
    Abstract: The invention relates to a thickened aqueous composition incorporating an amine or diamine, carrying at least one nitrogen linked hydrocarbon group which represents a saturated or unsaturated linear or branched alkyl group having at least 10 carbon atoms and preferably 16-24 carbon atoms or an aryl, aralkyl or alkaryl group containing up to 24 carbon atoms, and wherein the optional other nitrogen linked groups are formed by optionally substituted alkyl groups, aryl groups or aralkyl groups or polyalkoxy groups, or wherein the amine is in the form of a heterocyclic ring, containing at least two nitrogen atoms, one of which being substituted by amino (lower) alkyl or hydroxy (lower) alkyl, while the ring is further bearing a linear or branched alkyl or alkenyl preferably reacted with fatty acids, or alkenyl group having at least 10 carbon atoms; cumene sulphonate, xylene sulphonate, toluene sulphonate or mixtures thereof, in their acid or salt form; and a weak acid having a pK value>2.

  • Patent number: 4842771
    Abstract: The invention relates to an aqueous composition incorporating quaternary ammonium salt or amine oxide surfactant and cumene sulphonate, xylene sulphonate, toluene sulphonate or mixtures thereof and displaying pronounced shear thinning behaviour, i.e., exhibiting high viscosities at low rates of shear and intended to be applied to non-horizontal structural surfaces.These compositions comprise:a. from 0.1% to 10% by weight of a surfactant selected from the group consisting of quaternary ammonium compounds and tertiary amine oxides,b. from 0.01% to 3% by weight of an organic anionic sulphonate selected from the group consisting of cumene sulphonate, xylene sulphonate, and toluene sulphonate, in their acid or salt form, and mixtures thereof, andc. water, wherein optionally one or more cleaning, disinfecting and/or odorizing agents may be dissolved or dispersed.Acid-containing compositions are preferred and more particularly those containing 1-10% by weight of citric acid or hydrochloric acid.
