  • Patent number: 7090878
    Abstract: A water composition that is fortified with at least one mineral and has a pH between about 2.5 and 9.5. The water composition has a redox potential that satisfies the following equation: 0?RP?(A?B*pH) wherein RP is the redox potential in millivolts of the mineral-containing water composition, pH is the pH of the mineral-containing water composition, A is 400 and B is 20. The mineral is preferably selected from calcium, iron, zinc, copper, manganese, iodine, magnesium, and mixtures of these. Moreover, the mineral-fortified water composition is preferably substantially free of flavor or sweetener compounds. Even more preferably, the water composition has no metallic taste or after-taste, a Hunter colorimetric “b” reading of less than 5.0, and an NTU turbidity value of less than 5.0.

  • Patent number: 5971645
    Abstract: A hand-held container for predissolving a predetermined amount of detergent with a predetermined amount of solvent comprises a housing, a resilient side wall, and a dispensing passage. The dispensing passage has a flow restriction portion and an applicator at the distal end. The container is intended for use with fluids with a viscosity of less than about 500 cP. When so used, and aligned to a dispensing orientation, fluid flows out of the dispensing passage at a rate from about 0 ml/min to about 300 ml/min, unless manual pressure is exerted on the resilient side wall.

  • Patent number: 5968204
    Abstract: Sheets capable of developing a positive electostatic charge are used for a variety of surface cleaning operations. Polyester fabric, non-woven and chemically bonded with an acrylic latex is used to dust surfaces, to clean clothes, furniture and carpets. A light solvent such as isopropanol can be used with the sheets to loosen gummy soils. In one mode, the sheets are used in a hot air clothes dryer to remove soils and detritus from garments. Processes for cleaning a variety of fabric and hard surfaces are conducted using the sheets.

  • Patent number: 5942485
    Abstract: Concentrated heavy duty liquid laundry detergent compositions containing an anionic surfactant component, polyhydroxy fatty acid amide surfactant and a water-soluble salt of toluene sulfonic acid, and containing no more than about 50% water. The concentration of all surfactants in the detergent compositions is greater than about 10% by weight of the composition. The anionic surfactant component comprises between about 50% and 100% alkyl polyethoxylate sulfates. The compositions are substantially clear and isotropic when prepared and remain stable after extended periods of time and under extreme conditions. Toluene sulfonate salts, although known hydrotropes, provides improved phase stability to the compositions unlike other standard hydrotropes and solvents.

  • Patent number: 5912408
    Abstract: Enzymes are used in a dry cleaning composition and process. Cleaning compositions comprising lipase, protease and/or amylase enzymes are applied to soiled fabrics in the presence of an organic solvent such as butoxy propoxy propanol to clean the fabrics. In a preferred mode, an enzyme-containing dry cleaning composition is releasably contained in a sheet substrate. The sheet is tumbled with soiled fabrics in a conventional home clothes dryer to clean soiled garments.

  • Patent number: 5849039
    Abstract: A process for removing a stain from a localized stained area on a fabric. The process comprises the following steps: (a) placing the stained area of the fabric over and in contact with an absorbent stain receiver; (b) applying a fluid cleaning composition, which comprises at least about 95%, by weight water, to the stain from a container having a dispenser spout with a distal tip; and (c) rubbing or pressing the cleaning composition into the stain using the distal tip of the spout. This process causes the stain to be transferred into the stain receiver before the fabric is used or subjected to conventional laundering or dry-cleaning processes.
