Definitions

  • the invention relates to soil and stain removal, and in particular to compositions in gel form for application to localised areas of fabric or other surfaces to facilitate the removal of stains.
  • Prespotters are often applied in the form of a detergent liquid to stains on clothes prior to laundering. Problems that may be encountered when using prespotters include spillage and a potential for mess. Powders are generally less convenient to use and less effective than liquid prespotters, and also have potential to create mess.
  • the invention provides a method of facilitating the removal of stains and/or soil from surfaces, which comprises heating a Vl-phase detergent composition above its melting point, applying it, prior to melting, or preferably in the molten state to the stained and/or soiled surface, optionally allowing it to cool and reform the Nl-phase, and subsequently removing it from the surface.
  • Vl-phases which are commonly referred to as ringing gels, are a well-known group of liquid crystal phases characterised by cubic symmetry, as revealed by X-ray diffraction, and easily recognisable as optically isotropic, immobile gels, which vibrate when struck, whence their common name.
  • Vl-phase the commonest and most preferred, for the purposes of this invention.
  • the latter is usually envisaged as comprising a cubic array of spherical micelles in a continuous aqueous medium and forms at concentrations intermediate between the mobile, optically isotropic Ll-phase and the viscous, optically anisotropic, hexagonally symmetrical H- phase (which is sometimes also referred to as the M-phase).
  • the Vl-phase tends to form Ll-phase micellar solutions directly on dilution or warming.
  • the V2-phase is envisaged as the inverse of the Vl-phase, with the surfactant as the continuous medium and the water as the cubically arrayed dispersed phase.
  • the II- and I2-phases are bicontinuous phases located respectively at concentrations between the H- and L ⁇ - (lamellar) phase, and between the L ⁇ - and H2-phases.
  • Vl-phase has a melting point (VI/L transition temperature) above 30°C more preferably above 40°, most preferably above 45°C, but below 80°C, more preferably below 70°, even more preferably below 60°C, most preferably below 55°C.
  • the surfactant typically comprises an ethoxylated non-ionic surfactant, e.g. an ethoxylated fatty or synthetic alcohol having: from 8 to 25 carbon atoms, usually 10 to 20, especially 12 to 18; and up to 50, usually up to 30, especially 3 to 20, ethyleneoxy groups.
  • ethoxylated non-ionic surfactant e.g. an ethoxylated fatty or synthetic alcohol having: from 8 to 25 carbon atoms, usually 10 to 20, especially 12 to 18; and up to 50, usually up to 30, especially 3 to 20, ethyleneoxy groups.
  • ethoxylated non-ionic surfactant e.g. an ethoxylated fatty or synthetic alcohol having: from 8 to 25 carbon atoms, usually 10 to 20, especially 12 to 18; and up to 50, usually up to 30, especially 3 to 20, ethyleneoxy groups.
  • ethoxylated fatty acids ethoxylated amine
  • the surfactant may also comprise alkanolamides amine oxides, and/or amphoteric or zwitterionic surfactants, typically in proportions less than 50% by weight of the total surfactant, usually less than 40%, preferably less than 30%, more preferably less than 20%, e.g. less than 15%, often less than 10%, most preferably less than 5%. Less preferably, the surfactant may comprise small amounts of anionic, or of cationic surfactant.
  • the invention is applicable to the prespotting of fabrics, such as clothes upholstery or carpets, the cleaning of hard surfaces such as walls, floors, work-surfaces, alloy wheel trim or toilet bowls, either domestic or in industrial and institutional environments such as hospitals, factories or abattoirs, or in removing deposits such as chewing gum or animal excrement from paths.
  • a preferred embodiment of the invention provides a ringing gel adapted for use according to the invention, packed in a microwaveable container.
  • the container may be a multi-dose bottle or jar of a material, which is transparent to microwaves, such as glass or plastic, and may optionally be fitted with liquid-dispensing means, such as an atomiser or spray attachment, or an applicator nozzle, optionally provided with distribution means, such as a porous pad of, e.g. polyurethane foam.
  • the container may be a unit dose sachet or ampoule.
  • the invention provides an absorptive pad impregnated with the ringing gel.
  • the pad may be of polyurethane or rubber foam, or of a non-woven fabric. It may be provided with a handle, to enable it conveniently to be heated by temporary immersion in hot water, as an alternative to microwaving, and also to facilitate rubbing of the stain with the heated pad.
  • the pad may be attached to one side of a base plate, or the inside of a dish of lesser depth than the pad, e.g. by means of adhesive or an inward projection or projections or incurved rim on the side of the dish, and a handle may be attached to the other side.
  • the pad is protected, when not in use, by a removable cover, such as a screw-on, snap-on or hinged lid.
  • a further embodiment of the invention provides a gel adapted for use according to the invention packed in a self-heating can, for use in situations where an independent source of heat is not available.
  • Self-heating cans of the type conventionally used for heating food or beverages may be employed.
  • the gel may comprise auxiliary cleaning adjuvants such as enzymes, bleach, stain removers, e.g. phosphonates, abrasive particles, optical brighteners, builders, e.g. citrates, carbonates, condensed phosphates or zeolites, alkalis, dyes, perfumes and preservatives.
  • auxiliary cleaning adjuvants such as enzymes, bleach, stain removers, e.g. phosphonates, abrasive particles, optical brighteners, builders, e.g. citrates, carbonates, condensed phosphates or zeolites, alkalis, dyes, perfumes and preservatives.
  • the molten gel may be maintained in a heated reservoir.
  • a VI ringing gel comprised:
  • the gel was melted at 50°C and charged to a plastic spray applicator. After cooling to ambient temperature the gel reformed. It showed no tendency to leak when the container was punctured or damaged.
  • the container was placed in a microwave oven and heated until the gel was fluid.
  • the fluid was sprayed onto an area of fabric, where it cooled and set rapidly.
  • the cooled gel showed no tendency to migrate to unsprayed areas, but was easily rinsed off the fabric with cold water.
  • Example I was repeated using a self-heating can, of a type used commercially to heat coffee, in order to effect melting, with similar results.
  • Example II 0.5% opacifier (LYTRON® 621) and 0.15% Perfume were added to the mixture of Example I, giving a perfumed, opaque ringing gel.
  • Ci6-is alkyl 20 mole ethoxylate EMPLLAN® KM20
  • EMPLLAN® KM20 Ci6-is alkyl 20 mole ethoxylate
  • the other alkoxylates used were:
  • Blends may be selected for use according to the invention, which are in the Vl-phase at normal ambient temperature.
