Definitions

  • This invention relates to aqueous liquid detergents, preferably for use as a laundry composition or in conjunction with a laundry detergent.
  • Liquid based laundry and additive compositions have been known for many years.
  • a major issue encountered with such compositions has been the achievement of a suitable viscosity for the formula: the liquid has to be viscous enough so that any particles are suspended yet have a sufficiently high degree of flow for ease of manufacture and dispense by a consumer. Further the liquid has to be stable for over time/shelf life of the product.
  • thickeners are used. These thickeners are rheology modifiers suitable for liquid detergents. They are used to associate a higher concentration of active ingredients and to aggregate them in a stable matrix.
  • thickening systems have been developed over the years but there is still room for improvement in such systems, particularly as regards to stability in the presence of oxidixing agents ⁇ such as H 2 O 2 ) , and for effectiveness in acidic water formulation.
  • oxidixing agents such as H 2 O 2
  • Different kinds of thickener are commercially available.
  • One class of thickener that is used extensively are those based upon polymeric-carboxylic acids and their salts .

  • a semi-polar nonionic surfactant e.g. amine oxide
  • a semi-polar nonionic surfactant e.g. amine oxide
  • the thickening system of the present invention it has been found that superior thickening of a liquid detergent composition can be achieved. Without wishing to be limited by theory it is postulated that the superior thickening effect is due to interaction between semi-polar nonionic surfactant and the nonionic surfactant, giving rise to a thickened liquid. Furthermore advantageously the thickening is achieved in the absence of conventional surfactants (such as LAS / mineral surfactants), which are associated with a negative environmental impact.
  • conventional surfactants such as LAS / mineral surfactants

  • the bleach is preferably peroxide bleach, most preferably hydrogen peroxide. Peroxide sources other than H2O2 can be used.
  • the composition comprises a surfactant.
  • the composition comprises from 0.001% to 99.99%, preferably 0.05% to 15%, e.g. about 7%, by weight of surfactant.

  • the composition is preferably used in a washing machine cycle and / or as a pre-soaker / soaker in a clothes cleaning operation, e.g. as a fabric treatment composition.
  • Amine Oxide and anionic surfactant were blended first to build up an ionic structure at alkaline pH, in which non ionic surfactants were added to increase the viscosity up to the final target.
  • Sulphuric acid was added following a two step process in order to better control the pH drop along with hydrogen peroxide stabiliser insertion. Such a method of manufacturing avoids repetitive pH variations risking to reduce the viscosity of the base.
