Definitions

  • the present invention relates to granular detergent compositions or components thereof containing cationic compounds with particulate/clay-soil removal/anti-redeposition properties and a hydrophobic organic peroxyacid bleaching system for use in laundry and dish washing processes.
  • a particularly important property of a detergent composition is its ability to remove paniculate type soils from a variety of fabrics during laundering. Perhaps the most important paniculate soils are the clay- type soils. Clay soil particles generally comprise negatively charged layers of aluminosilicates and positively charged cations (e.g. calcium) which are positioned between and hold together the negatively charged layers.
  • positively charged cations e.g. calcium
  • a variety of models can be proposed for compounds which would have paniculate/ clay-soil removal properties.
  • One model requires that the compound have two distinct characteristics. The first is the ability of the compound to adsorb onto the negatively charged layers of the clay particle. The second is the ability of the compound, once adsorbed, to push apart (swell) the negatively charged layers so that the clay particle loses its cohesive force and can be removed in the wash water.
  • a model proposed for the anti-redeposition action of the positively charged anti-redeposition compounds is as follows. Adsorption of the positively charged molecule on the surface of clay particles in the wash water gives the particles the dispersancy properties of the molecule. As more and more of these compounds adsorb onto the suspended clay soil particles, the latter become encased within a hydrophilic layer provided by the attached ethoxy units. As such the hydrophilically encased soil is prevented from redepositing on fabrics, in particular hydrophobic fabrics such as polyester, during the laundering or dish washig cycle.
  • Another component traditionally used in detergent is bleach, to remove bleachable stains or soils from the fabric.
  • a disadvantage of the use of most bleaches is that various other detergent components are bleach sensitive and that they can be oxidised by the bleach, whereby their original properties can be diminished. Thus, not all detergent components are bleach- compatible.
  • cationic, (partially) quatemized ethoxylated (poly) amines which have clay-soil removal/anti- redeposition properties, are fully compatible with bleaches formulated therewith.
  • hydrophobic bleaches despite their tendency to migrate to the (hydrophobic) fabric surface, they do not necessarily interact fully with the bleachable stain or soil components. It has been found that the hydrophobic bleaches can be prevented from migration onto hydrophobic bleachable stains/soils by deposited clay-soil particulates on the fabric. Thereby, their bleaching performance can be diminished. This result in a lessening of the bleachable/ dingy soil cleaning performance of the hydrophobic bleach.
  • a detergent composition comprising a hydrophobic bleach. It has been found that in detergent compositions comprising both components the bleach efficacy of the hydrophobic organic peroxyacid bleaching system is enhanced. Thereby, the overall cleaning performance of the detergent is improved, which is especially noticeable on fabric stained with organic clay-soil particules, such as peat stains.

  • the mean particle size is such that from 10% to 50% of the particles has a particle size of from 0.2mm to 0.7mm in diameter.
  • the term mean particle size as defined herein is calculated by sieving a sample of the composition into a number of fractions (typically 5 fractions) on a series of sieves, preferably Tyler sieves. The weight fractions thereby obtained are plotted against the aperture size of the sieves. The mean particle size is taken to be the aperture size through which 50% by weight of the sample would pass.
  • the bulk density of granular detergent compositions in accordance with the present invention typically have a bulk density of at least 600 g/litre, more preferably from 650 g/litre to 1200 g/litre.

  • the funnel is 130 mm high and has internal diameters of 130 mm and 40 mm at its respective upper and lower extremities. It is mounted so that the lower extremity is 140 mm above the upper surface of the base.

  • the funnel is filled with powder by hand pouring, the flap valve is opened and powder allowed to overfill the cup.
  • the filled cup is removed from the frame and excess powder removed from the cup by passing a straight edged implement eg; a knife, across its upper edge.
  • the filled cup is then weighed and the value obtained for the weight of powder doubled to provide a bulk density in g/litre. Replicate measurements are made as required.
  • Compacted solids may be manufacmred using any suitable compacting process, such as tabletting, briquetting or extmsion, preferably tabletting.
  • tablets for use in dish washing processes are manufacmred using a standard rotary tabletting press using compression forces of from 5 to 13 KN/cm 2 , more preferably from 5 to 11 KN/cm 2 so that the compacted solid has a minimum hardness of 176N to 275N, preferably from 195N to 245N, measured by a C 100 hardness test as supplied by I. Holland instruments.
  • This process may be used to prepare homogeneous or layered tablets of any size or shape.
  • Preferably tablets are symmetrical to ensure the uniform dissolution of the tablet in the wash solution.
  • Machine laundry methods herein typically comprise treating soiled laundry with an aqueous wash solution in a washing machine having dissolved or dispensed therein an effective amount of a machine laundry detergent composition in accord with the invention.
  • an effective amount of the detergent composition it is meant from lOg to 300g of product dissolved or dispersed in a wash solution of volume from 5 to 65 litres, as are typical product dosages and wash solution volumes commonly employed in conventional machine laundry methods.
  • a dispensing device is employed in the washing method.
  • the dispensing device is charged with the detergent product, and is used to introduce the product directly into the dmm of the washing machine before the commencement of the wash cycle.
  • Its volume capacity should be such as to be able to contain sufficient detergent product as would normally be used in the washing method.
  • the dispensing device containing the detergent product is placed inside the dmm before the commencement of the wash, before, simultaneously with or after the washing machine has been loaded with laundry.
  • water is introduced into the dmm and the dmm periodically rotates.
  • the design of the dispensing device should be such that it permits containment of the dry detergent product but then allows release of this product during the wash cycle in response to its agitation as the dmm rotates and also as a result of its contact with the wash water.
  • the device may possess a number of openings through which the product may pass.
  • the device may be made of a material which is permeable to liquid but impermeable to the solid product, which will allow release of dissolved product.
  • the detergent product will be rapidly released at the start of the wash cycle thereby providing transient localised high concentrations of product in the dmm of the washing machine at this stage of the wash cycle.
  • Preferred dispensing devices are reusable and are designed in such a way that container integrity is maintained in both the dry state and during the wash cycle.
  • Especially preferred dispensing devices for use with the composition of the invention have been described in the following patents; GB-B-2, 157, 717, GB-B-2, 157, 718, EP-A- 0201376, EP-A-0288345 and EP-A-0288346.
