Definitions

  • liquid detergent composition that removes soils and/or stains of solid or solidified fatty material in the main wash at neutral pH. It is an object of the present invention to provide a composition that provides fast dissolution of solid fatty material.
  • the invention provides a p rocess for preparing a micro-emulsion according to any one of claims 1 to 9 comprising the steps in sequence of: adding in the surfactant system to an oil/solvent, mixing them together by an overhead stirrer, adding optional hydrophobic ingredients, adding aqueous phase containing electrolytes.
  • the invention relates to bi-continuous micro-emulsion detergent composition.
  • the bi-continuous micro-emulsions according to the invention are typically Newtonian liquids. They are typically not shear thinning.
  • liquid laundry or fabric cleaning compositions, fabric conditioning compositions and household cleaning compositions preferably comprise not more than 80% by weight, more preferably not more than 70% by weight, still more preferably not more than 60% by weight, or even not more than 50% by weight.
  • the surfactant system of the compositions of the present invention comprises a linear or branched fatty alcohol or a condensation product of a linear or branched fatty alcohol and alkylene oxide (e.g. ethylene oxide and/or propylene oxide), preferably ethylene oxide (also known as ethoxylated fatty alcohol or alcohol ethoxylate).
  • alkylene oxide e.g. ethylene oxide and/or propylene oxide
  • ethylene oxide also known as ethoxylated fatty alcohol or alcohol ethoxylate
  • the linear or branched fatty alcohol chain comprise s from 5 to 8 carbon atoms.
  • the number of alkylene oxide groups is not more than 5, preferably between 1 and 4.
  • Ethylene oxide (EO) groups are the most preferred.
  • Such surfactants include anionic surfactants, cationic surfactants, non-ionic surfactants, zwitterionic surfactants and/or amphoteric surfactants and mixtures thereof.
  • anionic and non-ionic surfactants are most preferred, while any surfactant may be used in household cleaning compositions.
  • the solubility of solid trilaurin (a triglyceride) fatty matter into the oil is more than 5%, or even more than 10%. This percentage is based on the aggregate amount of the oil and/or solvent and the trilaurin dissolved therein.
  • the melting point of said fatty acid ester is preferably less than 40°C, more preferably less than 10°C and most preferably less than 5 °C.
  • the aqueous composition comprises water and an electrolyte.
  • monovalent electrolytes are present in a concentration of between 1 and 15% based on the aqueous solution.
  • the bleach ingredient preferably has a low solubility in water (less than 200 ppm at 30 °C), but high solubility (more than 0.5% by weight) in oil/solvent.
  • the bleach ingredient is preferably solubilised in the oil/solvent phase of the bi-continuous micro-emulsion. It is expected that the bleach ingredient acts on soil during the interaction of oil droplets with the soiled substrates.
  • the pH of the composition is preferably acidic to neutral for stability reasons; the preferred pH is in the range of 5 to 7.
  • Mosquito repellent ingredients such as citrodora oil, citronella oil, lemon grass oil and their mixtures. May be incorporated up to 30 % by weight. Mosquito repellency has been demonstrated on shirts, washed with compositions containing at least 6 % by weight of any one of the above agents and mixtures thereof.
  • Perfume may be incorporated in the composition in a concentration of between 0.1 and 5% by weight. Typically the concentration is less than 3%, even less than 2%; generally the perfume is present in a concentration of between 0.5 and 1 % by weight. It is demonstrated that perfume incorporated in a micro-emulsion provides up to 10 times better deposition on fabrics and the perfume remains for a longer period compared to only surfactant solution containing equivalent amount of perfume.
