Definitions

  • detergents contain a number of active ingredients in order to provide numerous detergent benefits brought about by individual active components.
  • a single gelling aid is employed for a single zone of the product.
  • Polysaccharide gelling aids have been found to be par- ticula.rly beneficial in stabilising gels (especially gels with a high water content such as >30wt%) which are then packaged in a water soluble / dispersible material.
  • a polysaccharide is used as a gelling it is preferably present in an amount of 0.25-4wt% of that zone.
  • An inorganic salt may be used to enhance the gelling ability of the gelling aid.
  • Preferred examples of such salts include magnesium and calcium salts, e.g. the sulphate and / or chloride thereof.
  • Silica gelling aids have been found to be particularly beneficial in stabilising gels containing bleaching agents (i.e. the bleaching agents such as pox-salts have been found to be stable in gels gelled by silica gelling aids) . Additionally / alternatively silica gelling aids have been found to be advantageous since the formation of gels with suitable aesthesis properties such as transparent / translucent gels.
  • the separate zones may be used to house antagonistic components (e.g. bleach in a first zone and enzyme in a second zone) .
  • the zone may be used (since in a preferred arrangement the zones are arranged concentricall ) so that the timing of the release of ac- tives from zones may be delayed relative to a second zone.
  • nonionic surfactants suitable for use include ethylene oxide condensate products of secondary aliphatic alcohols containing 11 to 1 ⁇ carbon atoms in a straight or branched chain configuration condensed with 5 to 30 equivalents of ethylene oxide.
  • examples of commercially available non-ionic detergents of the foregoing type are Cu-is secondary alkanol condensed with ei- ther 9 equivalents of ethylene oxide (Tergitol 15-S-9) or 12 equivalents of ethylene oxide (Tergitol 15-S-12) marketed by Union Carbide, a subsidiary of Dow Chemical.
  • Octylphenoxy polyethoxyethanol type nonionic surfactants for example, Triton X-100, as well as amine ox- ides can also be used as a nonionic surfactant.
  • nonionic surfactants are amine oxides, alkyl amide oxide surfactants.
  • Preferred anionic surfactants are frequently provided as alkali metal salts, ammonium salts, amine salts, ami- noalcohol salts or magnesium salts.
  • surfactants which may be used are alkyl naphthalene sulfonates and oleoy.l sarcosinates and mixtures thereof.
  • Any suitable soil catcher may be employed. Unlike detergents or surfactants, which simply aid in the removal of soils from surfaces, the soil catcher actively binds to the soil allowing it to be removed from the surface of the laundry. Once bound, the soil is less likely to be able to redeposit onto the surface of the laundry.
  • Preferred soil catchers have a high affinity to both oily and water-soluble soil.
  • the soil catcher is a mixture of two or mere, soil catchers, each soil catcher may have a different affinity for different soils.
  • Preferred soil catchers for oily soils have a non polar structure with high absorption capability.
  • Preferred water based soil catchers are generally charged and have a high surface area in order to attract the soil by electrostatic charge and collect it.
  • ethylidene norbene poly- mers ethylidene norbene/ethylene copolymers/ ethylidene norbene/propylene/ethylidene ter-polymers .
  • Inorganic materials may also be employed. Examples include zeolites, talc, bentonites and active carbon. The latter may be used to absorb and/or degrade coloured parts of stain and/or absorb odours. Alginates, carrageneans and chitosan may also be used.
  • the product advantageously additionally comprises cleaning agents selected from the group consisting of,, fillers, builders, chelating agents, activators, fragrances, enzymes or a mixture thereof.
  • cleaning agents selected from the group consisting of,, fillers, builders, chelating agents, activators, fragrances, enzymes or a mixture thereof.
  • These active agents are generally water soluble, so dissolve during the wash. Thus the additional active agents are released over a period of time when exposed to water in the laundry washing machine.
  • Suitable carboxylates containing one carboxy group include the water soluble salts of lactic acid, glycolic acid and ether derivatives thereof.
  • Polycarboxylates containing two carboxy groups include the wa er-soluble salts of succinic acid, malonic acid, (ethylenedioxy) diacetic acid, maleic acid, diglycolic acid, tartaric acid, tartronic acid and fumaric acid, as well as the ether carboxylates and the s lfinyl carboxylates.
  • Polycarboxylate containing four carboxy groups include oxydisuccinates disclosed in GB-A-1, 261, 829, 1,1,2,2- ethane tetracarboxylates, 1, 1 , , 3-propane tetracarboxy- lates and 1, 1, 2, 3-propane tetracarobyxlates.
  • Polycar- boxylates containing sulfo substituents include the sul- fosucclnate derivatives disclosed in GB-A-1, 398, 21, GB- A-l., 398, 22 and US-A-3, 936448, and the sulfonated pyro- lysed citrates described in GB-A-1, 39,000.
  • the preferred polycarboxylates are hy- droxycarboxylates containing up to three carboxy groups per molecule, more particularly citrates.
  • More preferred polymers are homopolymers, copolymers and multiple polymers of acrylic, f.luorinated acrylic, sulfonated styrene, maleic anhydride, methacrylifc, iso- butylene, styrene and ester monomers.
  • acrylic, f.luorinated acrylic, sulfonated styrene, maleic anhydride, methacrylifc, iso- butylene, styrene and ester monomers are Acusol supplied from Rohm & Haas, Syntran supplied from Interpolymer and the Versa and Alcosperse series supplied from Alco Chemical, a National Starc & Chemical Company.
  • the parent acids of the monomeric or oligomeric polycar- boxylate chelating agents or mixtures thereof with their salts e.g. citric acid or citrate/citric acid mixtures are also contemplated as useful builder components.
  • builders are compounds that sequester metal ions associated with the hardness of water, e.g. calcium and magnesium, whereas chelating agents are compounds that sequester transition metal ions capable of catalysing the degradation of oxygen bleach systems.
  • chelating agents are compounds that sequester transition metal ions capable of catalysing the degradation of oxygen bleach systems.
  • certain compounds may have the ability to do perform both functions.
  • a preferred biodegradable chelating agent for use herein is ethylene diamine ⁇ , ⁇ ' -disuccinic acid, or alkali metal, or alkaline earth, ammonium or substituted ammonium salts thereof or mixtures thereof, Ethylenediafnine N, ' -disuccinic acids, especially the (S,S) isomer have been extensively described in US patent 4, 704, 233, November 3, 1987, to Hartmart and.
