Definitions

  • This invention relates to alkaline thickened liquid hydrogen peroxide bleaching compositions. More particularly, this invention relates to such alkaline thickened bleaching compositions which are highly stable in terms of providing a uniform and thickened viscosity which remains stable over time, concomitant with the ability to maintain a stable bleaching activity during extended periods of storage prior to use by the consumer.
  • Hydrogen peroxide compositions have been the focus of much attention in the patent literature in recent years as replacements for or as alternatives to halogen-containing bleaches, often motivated by environmental considerations.
  • interest has focused on alkaline hydrogen peroxide bleaches because of their greater reactivity and enhanced bleaching efficacy as compared to acidic hydrogen peroxide compositions.
  • One of the prime requirements of a bleach intended for domestic use is that the bleaching species remain sufficiently stable to insure good efficacy of the bleach product upon use by the consumer, typically many months after the products manufacture.
  • Hydrogen peroxide solutions are known to provide enhanced bleaching efficacy when used under alkaline conditions.
  • stabilization of hydrogen peroxide is particularly troublesome at such alkaline conditions.
  • the problem of bleach stability is often exacerbated when formulating a thickened bleach product.
  • Thickening of a pourable liquid bleach is intended to provide an enhanced aesthetic appearance of the product as well as assist the consumer to control dispensing of the liquid bleach product.
  • a thickened composition also serves to limit the rate at which the composition flows or drains from the surfaces to which it is applied.
  • a thickening agent or thickening system in the bleach composition presents problems in formulation: it is often incompatible with peroxide bleach stabilizers which are otherwise effective in non-thickened compositions, or the thickening agents themselves may provide an uneven viscosity to the liquid bleach product and, in general, adversely affect product appearance and flow characteristics depending on variables such as product pH or the non- bleach ingredients, such as electrolyte, present in the composition.
  • EP 376 704 describes hydrogen peroxide aqueous solutions which contain a combination of surfactant and electrolyte to provide thickening and bleach stability.
  • UK patent application GB 2 273 721 describes a thickened bleach composition which comprises an alkaline aqueous solution of hydrogen peroxide containing as the thickening system a mixture of a quaternary long chain alkyl ammonium compound together with a salt of an aromatic sulphonic acid hydrotrope.
  • U.S. Patent 5,736,498 is concerned with alkaline hydrogen peroxide compositions which are thickened with a polymeric thickener having a polyethylene backbone.
  • U.S. Patent 4,900,469 describes a thickened laundry composition comprising a surfactant thickening system, a hydrogen peroxide bleach and a stabilizing system consisting of a chelating agent and an antioxidant.
  • a C6-C ⁇ 8 soap is optionally included to increase viscosity.
  • the present invention provides an alkaline thickened liquid bleaching composition comprising, by weight:
  • a method of bleaching fabrics comprising the step of contacting the fabrics to be bleached with an effective amount of the above-described alkaline thickened liquid bleaching composition.
  • the present invention is predicated on the discovery that thickening of a hydrogen peroxide bleach solution can be effectively provided with a surfactant mixture of alkyl dimethylamine oxide and soap as herein described in combination with a weak electrolyte such as an alkali metal sulfate, such that a stable commercially desirable viscosity in the range of from about 80 to 500 cps can be readily achieved, preferably from about 100 to 300 cps, without adversely affecting the stability of the peroxide bleach.
  • a surfactant mixture of alkyl dimethylamine oxide and soap as herein described in combination with a weak electrolyte such as an alkali metal sulfate, such that a stable commercially desirable viscosity in the range of from about 80 to 500 cps can be readily achieved, preferably from about 100 to 300 cps, without adversely affecting the stability of the peroxide bleach.
  • the amount of hydrogen peroxide bleach present in the composition of the invention may vary from about 0.1% to about 10%, by weight, of the total composition.
  • Preferred compositions comprise from about 2% to about 6%, by weight.
  • the surfactant mixture which forms part of the thickening system is comprised of an alkyl dimethylamine oxide and a neutralized C 6 -C 18 fatty acid, such mixture being present in an amount of from about 1.5 to 8%, by weight, preferably from about 2% to 4%, by weight.
  • the alkyl group in the dimethylamine oxide surfactant contains from about 11 to 16 carbon atoms.
  • a preferred alkyl group is comprised of a mixture of carbon chain lengths comprising 33% to 43% of C ⁇ 2 ; from 42% to 52% of d 4 ; and from 4% to 14% of C 16 .
  • Lauryl is a particularly preferred alkyl group.
  • the second component of the surfactant mixture is a C 6 -C ⁇ 8 fatty acid which is neutralized in-situ by the alkali metal hydroxide in the liquid composition to form a C 6 -C ⁇ 8 soap.
  • Typical fatty acids include capric acid, lauric acid, any myristic acid, but most preferred is coconut fatty acid which after neutralization forms the coconut lauryl soap.
  • the ratio of the described amine oxide surfactant to the fatty acid soap is generally from about 1.5:1 to about 6:1, and preferably from about 2: 1 to about 4:1.
  • the third component of the thickening system which serves to stabilize the increased viscosity provided by the surfactant mixture is an alkali metal sulfate such as sodium or potassium or magnesium sulfate. Sodium sulfate is preferred as a source of weak electrolyte which serves to stabilize the viscosity of the composition without adversely affecting the stability of the hydrogen peroxide in solution.
  • the peroxide bleach stabilizer used herein is a polyphosphonate sequestrant.
  • suitable phosphonate stabilizers include sodium or potassium salts of HEDP 1 and EDTMP 2 .
  • pentasodium salt of diethylenetriamine penta methylene phosphonic acid
  • An essential ingredient in the present bleaching composition is an alkali metal hydroxide such as sodium or potassium hydroxide, in an amount sufficient to neutralize in-situ the fatty acid ingredient present in the surfactant mixture so as to form the soap.
  • the alkali metal hydroxide also serves to provide an alkaline pH in the liquid bleach composition of from 8 to 9.5, and preferably from 8.2 to 9.2.
  • the amount of alkali metal hydroxide in the composition is generally from about 0.10 to 0.5%.
  • the liquid bleach compositions may preferably include a pH buffer such as sodium benzoate which serves to stabilize the pH of the composition and thereby assists in stabilizing the peroxide bleach.
  • a pH buffer such as sodium benzoate which serves to stabilize the pH of the composition and thereby assists in stabilizing the peroxide bleach.
