Definitions

  • the present invention relates to fabric treatment compositions and, in particular, to compositions which include a fabric whitening agent.
  • the compositions of the invention are particularly, but not exclusively, suitable for the treatment of fine or delicate 10 fabrics.
  • a whitening composition In the washing of fabrics, in particular of clothes, it is known to use a whitening composition either separately (for example as a pre-wash composition) or
  • Such liquid formulations are not suitable for treatment of fine or delicate fabrics because of the aggressive nature of the hypochlorite with regard to the fabric and the colour.
  • liquid compositions based on hydrogen peroxide have been suggested, since hydrogen peroxide has less aggressive properties and is less likely to damage fine or delicate fabrics or
  • Thickened compositions provide advantages in use as compared with unthickened compositions and consumer preference for thickened products is well documented. For example, if the laundry composition is to be used as a pre-wash, a thickened composition is more easily applied directly onto difficult stains before the normal washing process without messy dripping. A thickened composition will also remain longer on the garment to which it is applied than an unthickened composition. Thickening of the composition also helps the user to control dispensing of the composition.
  • compositions based on hydrogen peroxide present problems in that the viscosity of the compositions is not stable with time.
  • liquid compositions based on hydrogen peroxide which are currently on the market are all believed to be simple unthickened hydrogen peroxide solutions containing a low concentration of surfactant, generally of not more than 2% surfactant.
  • Prior art hydrogen peroxide bleaching/cleaning products have frequently been thickened by using a combination of surfactants which, in the presence of an electrolyte, act to thicken the solution so that it becomes more viscous than water.
  • GB 2286603 (Jeyes Group PLC) describes a thickened aqueous alkaline peroxide bleaching agent composition containing hydrogen peroxide, water, a stabliliser for the hydrogen peroxide, a water-soluble electolyte and a surfactant/thickening component comprising: i) an alkyl ether sulphate surfactant together with an amine oxide or betaine surfactant and, optionally, an alkane sulphonate surfactant; or ii) an amine oxide surfactant together with a sarcosinate surfactant and, optionally, an alkane sulphonate surfactant.
  • the presence of an electrolyte tends to accelerate decomposition of alkaline hydrogen peroxide solutions.
  • GB 2273721 (Jeyes Group PLC) also describes a thickened bleach composition
  • a thickened bleach composition comprising an alkaline aqueous solution of hydrogen peroxide containing, as a thickening system, two different surfactants - a cationic and anionic surfactant - which interact to give the desired viscosity.
  • thickened fabric treatment compositions based on hydrogen peroxide, in particular fabric whitener compositions having satisfactory stability with regard to hydrogen peroxide decomposition and viscosity can be provided by employing an associative thickening agent as the thickening medium.
  • One advantage of the compositions of the present invention over the prior art surfactant-thickened compositions is that a smaller amount of active ingredients is needed to thicken the compositions to the desired viscosity.
  • the present invention provides a thickened liquid fabric treatment composition based on hydrogen peroxide which is sufficiently stable over time with respect to both viscosity and hydrogen peroxide decomposition.
  • a thickened liquid fabric treatment composition in particular a fabric whitener composition, comprising hydrogen peroxide, one or more surfactants and an associative thickening agent.
  • Thickened compositions we mean compositions of increased viscosity. Thickened compositions according to the invention are those which have a viscosity of from about 30 mPaS to 30 000 mPaS.
  • an appropriate viscosity for a pourable composition having the appearance of a thick liquid is a viscosity in the range of from about 30 to 600 mPas . More viscous liquids, for example with a viscosity of from 600 to 10 000 mPas or more are also within the scope of the invention.

  • the viscosities of the compositions of the present invention are measured using a Brookfield Viscometer on a No.2 spindle at 25°C
  • Associative thickeners are water-soluble or water-swellable polymers that have chemically attached hydrophobic groups that are capable of non-specific hydrophobic associations.
  • the associative thickening agents utilized in the present invention are non-ionic agents with hydrophobic and hydrophilic sequences which are effective over a wide pH range (pH 2-12) .
  • the hydrophobic parts of the thickener build up associations with the other hydrophobes present in the formulation. This allows the thickening agents to demonstrate a good synergistic thickening effect when used in conjunction with low water-soluble ingredients.
  • the associative thickening agents employed in the present invention will typically have a general structure similar to that illustrated in Figure 1.
  • the structure of the preferred associative thickening agents generally resembles in shape a so-called barbell (or dumb-bell) structure or a comb structure.
  • the typical associative thickening agents in accordance with the invention will comprise a central hydrophilic portion and end portions which are hydrophobic.
  • associative thickening agents having a central hydrophobic portion and end portions which are hydrophilic may be employed where appropriate.
  • the associative thickening agents may alternatively be polymers having alternate hydrophilic and hydrophobic portions .
  • Particularly suitable associative thickening agents for use in accordance with the present invention are low to medium molecular weight dialkyl polyglycol ethers.
  • low to medium molecular weight we mean compounds having a molecular weight ranging from a few hundred to tens of thousands.
  • particularly preferred associative thickening agents are dialkyl polyglycol ethers sold by Akzo under the tradenames DAPRAL T210 and DAPRAL T212, both of which have a molecular weight of about 8000.
  • Dapral T210 is especially suitable because of its particular viscoelastic properties.
  • a combination of both DAPRAL T210 and DAPRAL T212 is used, which results in a composition with particularly desirable rheological properties.

  • a soap may also be included.

  • a particularly preferred anionic surfactant is lauryl ether sulphate 3EO (having 3 moles of ethylene oxide) which is available under the tradename SIPON LES 328n from Sidobre Sinnova.
  • the choice of surfactant in the composition can depend on the material for which the composition is intended and on the type of soil on the fabric. For example, for use on wool, a greater quantity of non-ionic surfactant will give better detergency, whereas a lesser quantity of non-ionic surfactant and more anionic surfactant gives lower levels of detergency but greater fabric softness.
