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.
  • micro-emulsion compositions 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 %. Under low temperature and high temperature conditions, often encountered while shipping product or storing product in a warehouse, microemulsions exhibiting stability in a fairly narrow temperature range tend to become unstable. As a result, the microemulsion phase separates and the effectiveness of the composition for removing soil is decreased. In addition, when such a phase separation occurs, it may take a considerable amount of time for the microemulsion to reform. In general, cleaning operations until a composition forms a microemulsion in order to obtain optimum cleaning benefits.
  • 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 Cold 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.
  • compositions with such high active levels have little formulation space left for fat solubilising materials such as oils.
  • 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 2011/073062 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.
  • a lamellar phase detergent composition comprising a surfactant selected from non-ionic and anionic surfactants in a ratio of non-ionic:anionic surfactant from 3:1 to 1:4 and having HLB value of not less than 15, a fat solubilising oil and water provides an effective solution that removes soils and/or stains containing solid or solidified fatty material; is stable at normal storage and washing conditions and may be delivered as a pourable liquid.
  • the present invention provides a liquid detergent composition
  • a surfactant selected from non-ionic and anionic surfactants in a ratio of non-ionic : anionic surfactant from 3:1 to 1:4 and having HLB value(Davies Scale) of not less than 15, 1.25-16% by weight of a fat solubilizing oil, having a Hansen solubility parameter (• HSP) that ranges from 14-22 MPa1/2 (at 25°C), and wherein the Hansen polar component (• P) is in the range of 0.5-10 MPa1/2 (at 25°C), the dispersion component (• H) is in the range of 3-10 MPa1/2 (at 25 °C) and the hydrogen bond component (• D) is in the range of 13-18 MPa1/2 (at 25°C); and water upto 100%; and wherein, the surfactant to fat solubilising oil ratio ranges from 2.5 to 8 and the fat solubilising oil on (fat solubilising oil + water) ratio ranges from 0.03
  • the invention provides a method for washing fabric articles comprising the steps of dosing between 2-20 ml of the composition according to the invention per litre of wash or cleaning liquor.
  • the present invention provides a liquid detergent composition
  • a liquid detergent composition comprising of a surfactant, a fat solubilising oil and water.
  • the detergent compositions according to the invention include 10 wt% to less than 40 wt% surfactant.
  • Surfactants are included in the formulation for primary cleaning action and are chosen from anionic and non-ionic surfactants.
  • the non-ionic and anionic surfactants are in a ratio such that the non-ionic : anionic surfactant ratio is from 3:1 to 1:4, preferably from 2:1 to 1:2.
  • the surfactant system according to the invention is defined by an HLB value.
  • HLB value defines the hydrophilic to lipophilic balance of the surfactant system.
  • the HLB system predicts the optimum emulsion stability when the HLB value of the surfactant system matches the required HLB of the oil/water system.
  • the required HLB is the value at which enhanced emulsion stability will be attained.
  • a stable lamellar phase detergent composition is obtained when the HLB value of the mixed surfactant system is not less than 15.
  • Anionic surfactants are well known in the art and are primarily important for soil removal. These include, but not limited to, carboxylates (soaps), such as Sodium laurate and Sodium myristate, dicarboxylates, sulphates, e.g. Sodium dodecyl sulphate (SDS) and sulphonates, e.g. Sodium salts of linear alkyl benzene sulphonates, more preferably, Sodium lauryl ether sulphate (SLES), preferably having 1 to 9 ethylene oxide groups; and Linear Alkylbenzene Sulfonate (LAS).

  • the Hansen Solubility Parameter (• HSP ) of sebum is from 15 to 18.5 Mpa 1/2 .
  • the • HSP of the solvent should not deviate too much from the • HSP of the sebum, hence the above ranges.
  • 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 1/2 .
  • 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 (• HSP ) 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). The three parameters are:
  • 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.

Hansen, CRC Press, Boca Raton, 2000 .
