  • Patent number: 6949496
    Abstract: The present invention relates to detergent compositions, especially liquid, granular and tablet forms of laundry detergent compositions, that comprise improved hydrotropes, wherein the hydrotropes are organic molecules in which two polar groups are separated from each other by at least 5 aliphatic carbon atoms; liquid compositions that contain such hydrotropes have a viscosity, dilution profile and dissolution behavior that render the product effective and convenient for use as a liquid laundry detergent composition.

  • Patent number: 6559115
    Abstract: The present invention relates to a tablet formed by compressing a particulate material, the particulate material comprising a surfactant and a highly soluble compound, the highly soluble compound having a cohesive effect on the particulate material. In a further aspect of the invention there is provided a method of preparing an aqueous solution of a laundry detergent for use in a washing machine, wherein the aqueous solution of laundry detergent is formed by dissolving in water a tablet formed by compressing a particulate material, the tablet comprising a surfactant and a highly soluble compound, the highly soluble compound having a cohesive effect on the particulate material.

  • Patent number: 6277808
    Abstract: A cleaning composition which is an oil-in-water or water-in-oil emulsion is disclosed. The composition includes (i) a non-aqueous hydrophobic solvent; (ii) a first anionic or nonionic surfactant having an alkyl chain, the length of the alkyl chain being C11 or less; (iii) a second anionic or nonionic surfactant having an alkyl chain, the length of the alkyl chain being C12 or more; and (iv) the pH of the cleaning composition being at least 8. Methods for using the cleaning composition for treating spots or stains on textile fabrics and laundry kits comprising the cleaning composition are also disclosed.

  • Patent number: 6048368
    Abstract: The present invention provides a more effective method of treating a spot or stain on a textile fabric, the method comprising the steps of: applying a detergent composition to the spot or stain; placing an absorbent layer adjacent to one side of the textile fabric in the region of the spot or stain; and applying heat, pressure, or heat and pressure, to the opposing side of the textile fabric in the region of the spot or stain, preferably in the presence of a hydrophilic solvent, or water, so that some or all of the spot or stain is absorbed into the absorbent layer. The detergent composition can be applied to the textile fabric using a container having a cap to which a foam pad is secured. The cap has a small opening through which the detergent composition can pass.
