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 micro- emulsions, in particular bi-continuous 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
- 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.
- 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.
- WO95/27034 discloses detergent compositions in the form of oil in water micro- emulsions providing rapid stain removal.
- the composition of WO95/27034 comprises a surfactant system comprising short chain length non-ionic alcohol ethoxylates having less than 12 carbon atoms and with at least 45% of C10 material.

What remains to be desired is a liquid detergent composition that removes soils and/or stains of solid or solidified fatty material in the main wash at neutral pH.

- a bi-continuous micro-emulsion has a microstructure of oil and water channels spanning across a sample (sample spanning) unlike discrete droplet configuration as found in oil-in-water (o/w) and/or water-in-oil (w/o) micro-emulsion types.
- sample spanning oil or water channels interact with hydrophobic or hydrophilic soils, present on substrates, equally well and help in faster solubilisation of soil/dirt, especially solid oily or fatty stains or soils.
- These structures may be characterised by various known experimental techniques, including electrical conductivity, viscosity, light scattering, SAXD, SANS and NMR self diffusion.
- the oil-water interfacial tension is the lowest in this structure compared to o/w or w/o type micro-emulsions.
