Definitions

  • the present invention is in the field of stable detergent compositions; in particular liquid crystal ternary lamellar phase detergent compositions, for use in laundry and/or household cleaning amongst others.
  • Liquid detergent compositions are widely known in the art and are widely favoured by modern day consumers. Such liquid detergent compositions are principally used in fabric cleaning and household care applications. Present day consumer's are looking for stable, non-phase separating and moderately viscous liquids for fabric cleaning and household care applications.
  • Liquid detergent compositions generally comprise a surfactant active and a solvent. They may further comprise perfume, bleach, thickeners, fluorescers, and other common detergent ingredients. Such 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.
  • Lamellar phase cleaning compositions as a vehicle for delivering typically surfactant blends to a cleaning location provide a solution to that has proved useful to a large extent.
  • a lamellar phase system consist of a surfactant bilayer packed with hydrophobic (water-rejecting) alkyl tails inwardly directed and polar hydrophilic (water-attracting) head groups on the outside surfaces.
  • the lamellar phase can be obtained at a certain range of temperature and can, under certain conditions, it is known to the skilled person that lamellar phases possess very high capacity to solubilise oil and fats.
  • Another option is to make the detergent composition in the form of a micro emulsion with an aqueous phase and a solvent. Typical micro-emulsion compositions, however, do not provide desired soil removal when challenged with cleaning of tough soils and mixtures of oily and particulate soils.
  • EP 637 629 A1 (Colgate Palmolive) discloses a stable, clear, all-purpose
  • microemulsion cleaner with surfactants 1 - 20 %.
  • surfactants 1 - 20 %.
  • microemulsions exhibiting stability in a fairly narrow temperature range tend to become unstable.
  • the microemulsion phase separates and the effectiveness of the composition for removing soil is decreased.
  • EP 160 762 A1 discloses a micro-emulsion sample comprising 1 -40%w of surfactant. It uses paraffin as solvent. Paraffin is not considered an effective solvent for sebum and polymerized fats majorly found in cuffs and collars. Also, paraffin has a reduced rate of biodegradability. Biodegradation refers to the ability of a material to be broken down by the action of bacteria and other living organisms. Most of the detergents containing paraffin have slow biodegradation and hence they may cause pollution.
  • WO 97/32967 A1 (Colgate Palmolive) discloses a liquid crystal detergent composition, and micro emulsions with 2-66% surfactants. However, it is found that the cleaning performance of the compositions of WO 97/32967 leaves to be desired, especially for fatty stains, such as sebum. This is thought to be caused by the lack of fat solubilising materials in the composition.
  • Our co-pending application 3328/MUM/201 1 describes lamellar phase detergent compositions comprising very high active levels of between 40% and 90% by weight of active material. However, compositions with such high active levels, have little formulation space left for fat solubilising materials such as oils. Hence, efficient cleaning of fabric articles, especially the removal of soils such as sebum from cuffs and collars, remains to be desired.
  • a further co-pending application WO 201 1/073062 discloses a bi-continuous micro- emulsion detergent composition comprising a short chain non-ionic surfactant, however micro-emulsions are typically less viscous and less temperature stable and therefore not appreciated by modern day consumers. To provide a temperature stable thickened detergent composition remains to be desired.

  • HLB value defines the hydrophilic to lipophilic balance of the surfactant system.

  • ⁇ H SP Hansen Solubility Parameter
  • Paraffin oil is not preferred, because the P and H values do not closely match that of sebum. This means that the polarity and hydrogen bonding of paraffin oil is less than optimal.
  • Hansen Solubility Parameters were developed by Charles Hansen as a way of predicting if one material will dissolve in another to form a solution. The parameters are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way. Specifically, each molecule is given three Hansen parameters, each generally measured in MPa /2 . The solubility parameter has been defined as the square root of the cohesive energy density and describes the attractive strength between molecules of the material.
  • Hansen assumed that the cohesive energy arises from the dispersive, permanent dipole-dipole interactions and hydrogen bonding forces.
  • the basis of the Hansen solubility parameter ( ⁇ H SP) is that the total energy of vaporisation of a liquid consists of several individual parts. Hansen has defined three types of contributions to the energy of vaporisation, namely: dispersive (D), polar (P) and hydrogen bonding (H).
  • Each of the three parameters represents a different characteristic of solvency, or solvent capability.
  • the three parameters are a measure of the overall strength and selectivity of a solvent.
  • the total Hansen solubility parameter which is the square root of the sum of the squares of the three parameters mentioned previously, provides a more general description of the solvency of the solvents.
