Definitions

  • the present invention is in the field of detergent compositions; in particular high active liquid detergent compositions, for use in laundry and/or household cleaning amongst others.
  • the compositions of the present invention relate to the field of water-in-oil micro-emulsions.
  • Liquid detergent compositions are widely appreciated and preferred by many modern day consumers in both developed and developing and emerging markets. Such liquid detergent compositions are primarily used in Laundry and household care applications.
  • Liquid detergent compositions are widely known in the art.
  • Liquid detergent compositions generally comprise a surfactant active and a solvent.
  • Liquid detergent compositions may further comprise perfume, builder, polymers, bleach, thickeners, fluorescers, and other common detergent ingredients.
  • Liquid detergent compositions are often structured, e.g. to control the viscosity of the liquid or to improve stability and prevent phase separation or to be able to incorporate ingredients that are water insoluble.
  • Present day liquid detergent compositions typically do not contain bleach and therefore do not work well on bleachable stains, such as coffee, tea, tomato and wine.
  • current liquid detergent products contain only low levels of surfactant, and therefore also do not meet the consumers' requirement for the removal of oily and fatty stains.
  • a stable liquid detergent composition is a detergent composition in the form of an emulsion.
  • a defined kind of emulsion is the micro-emulsion.
  • emulsions are opaque liquids which are not appreciated by modern day consumers.
  • Micro-emulsions can be made transparent and typically have a lower viscosity too.

It is found that these oil in water micro-emulsions do not provide adequate dissolution of fatty stains and soils when applied neat. Fast fat (or oily soil) solubilisation when applied neat onto a fatty stain or soil remains to be desired for amongst other the dissolution of sebum on shirt collars and fatty soils on hard surfaces.
