Abstract: A composition is provided comprising two liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent and a second liquid preferably includes a peroxygen agent. The first liquid is thickened to a specified rheology, resulting in the generation of a highly effective foam. As the two liquids are initially separated, the hypohalite generating agent can be maintained in an environment free of peroxygen agent and otherwise conducive to their cleaning activity and stability up to the time of use. When the two liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe.

Abstract: A composition is provided comprising three liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a heated foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent, a second liquid preferably includes a peroxygen agent and a third liquid includes a reducing agent, such as a thiosulfate. The first liquid is thickened to a specified rheology, resulting in the generation of a highly effective foam. As the liquids are initially separated, they can be maintained in an environment free of reactants and otherwise conducive to their activity and stability up to the time of use. When the liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas, while the hypohalite and thiosulfate react to generate heat.

Abstract: A structure for venting of gasses from fluids, and in particular, venting of gasses from filter elements or filter media used in water treatment devices. The structure incorporates a fluid flow diverter having a vent tube, tangential flow diverter and a lower air collection space to vent air from an interface between stages of the filter cartridge. The vent structure is particularly suited to systems having a pressure drop of 1 psi or less, such as those systems which filter a fluid by a pressure differential generated by gravity alone, or aided by a manual pressurization means. There is also disclosed a multi-stage filter cartridge, incorporating the vent structure, and having an upper stage including granular carbon and a lower stage including a plurality of hollow fibers.

Abstract: A composition is provided comprising two liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent and a second liquid preferably includes a peroxygen agent. As the two liquids are initially separated, the hypohalite generating agent can be maintained in an environment free of peroxygen agent and otherwise conducive to their cleaning activity and stability up to the time of use. When the two liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe. The expanded foam contains an excess of the hypohalite, which acts to clean the drain.

Abstract: A cleaning formulation, in tablet form, capable of providing uniform delivery of cleaning agents, fragrance and colorants while immersed in a the tank of a toilet.

Abstract: The present invention provides an abrasive-free cleaning composition which includes, in aqueous solution, a bleach, a colloidal thickener, and a source of divalent ionic calcium. The composition further includes at least one surfactant which is effective to provide cleaning activity and, in association with the colloidal thickener, thickening. The composition also includes an electrolyte/buffer which is effective to promote an environment in which the thickener and the surfactant associate to provide proper thickening. The inventive cleaning composition, with its ionic calcium source, has desirable viscosity and rheological properties, and demonstrates significant viscosity stability, rheological stability, phase stability and bleach stability. The cleaning composition maintains these desirable properties under typical storage conditions as well as over extended times and at elevated temperatures.

Abstract: The invention provides a process, and an article of manufacture, in which a blown, hollow plastic article which has a paper label applied by in-mold labelling, must have the label positioned such that the longitudinal fibers thereof are oriented substantially with respect to the longest axis of the blown, hollow plastic article.

Abstract: A method for opening drains using a phase stable, viscoelastic drain opening composition includes introducing to a drain pipe restriction or clog a mixture having a cleaning active and a viscoelastic thickening system containing a quaternary ammonium compound, an organic counterion, and a free amine. The amount of free amine in the composition is limited, and is based on the amount of the quaternary ammonium compound present, in order to maintain phase stability and to achieve further enhanced rheological and aesthetic properties in the composition. The viscoelastic quality of the composition permits rapid penetration of the formulation through standing water with minimal dilution to deliver actives to the clog material, thus providing advartageous utility as a drain opener.

Abstract: The invention provides a phase stable, thickened aqueous abrasive cleanser and a method for preparing it, said cleanser comprising:a) an effective amount of a cross-linked polyacrylate;b) an effective amount of at least one bleach-stable surfactant;c) an effective amount of a low salt, high purity hypochlorite;d) an effective amount of a pH-adjusting agent;e) an effective amount of abrasive; andf) the remainder as water.
