Definitions

  • the invention relates to structured cleaning compositions
  • liquid cleaning compositions containing suspended abrasive particles, which are suitable for use as manual dishwashing and scouring liquids
  • EP 0193375 describes dispersing fine particles of sodium carbonate in a viscous, liquid detergent base, relying on the high viscosity of the medium, and the small particle size of the carbonate to retard sedimentation
  • the small particle size gives insufficient abrasive action for an effective pan scourer
  • structured system means a pourable composition comprising water, surfactant, any structurants which may be required to impart suspending properties to the surfactant, and optionally other dissolved matter, which together form a mesophase, or a dispersion of a mesophase in a continuous aqueous medium, and which has the ability to immobilise non-colloidal, water- insoluble particles while the system is at rest, thereby forming a stable, pourable suspension
  • L ⁇ -phases also known as G-phases
  • aqueous layers L ⁇ -phases also known as G-phases
  • Such evidence may comprise first, second and sometimes third order peaks with a d-spacing (2 ⁇ /Q, where Q is the momentum transfer vector) in a simple integral ratio 1 2 3
  • Other types of symmetry give different ratios, usually non-integral
  • the d-spacing of the first peak in the series corresponds to the repeat spacing of the bilayer system
  • the main types of structured system used in practice are based on dispersed lamellar, spherulitic and expanded lamellar phases
  • Dispersed lamellar phases are two phase systems, in which the surfactant bilayers are arranged as parallel plates to form domains of L ⁇ -phase, which are interspersed with an aqueous phase to form an opaque gel-like system They are described in EP 086 614
  • Spherulitic phases comprise well-defined spheroidal bodies, usually referred to in the art as spheruhtes, in which surfactant bilayers are arranged as concentric shells
  • the spherulites usually have a diameter in the range 0 1 to 15 microns and are dispersed in an aqueous phase in the manner of a classical emulsion, but interacting to form a structured system Spherulitic systems are described in more detail in EP 151 884
  • a variant on the spherulitic system comprises prolate or rod shaped bodies sometimes referred to as batonettes These are normally too viscous to be of practical interest
  • Both of the foregoing systems comprise two phases Their stability depends on the presence of sufficient dispersed phase to pack the system so that the interaction between the spheruhtes or other dispersed mesophase domains prevents separation If the amount of dispersed phase is insufficient, e g because there is not enough surfactant or because the surfactant is too soluble in the aqueous phase to form sufficient of a mesophase, the system will undergo separation and cannot be used to suspend solids Such unstable systems are not "structured" for the purpose of this specification
  • a third type of structured system comprises an expanded L ⁇ -phase It differs from the other two types of structured system in being essentially a single phase, and from conventional L ⁇ - phase in having a wider d-spacing
  • Conventional L ⁇ -phases which typically contain 60 to 75% by weight surfactant, have a d-spacing of about 4 to 7 nanometers Attempts to suspend solids in such phases result in stiff pastes which are either non-pourable, unstable or both Expanded L ⁇ -phases with d-spacing greater than 8 nanometres, e g 10 to 15 nm, form when electrolyte is added to aqueous surfactants at concentrations just below those required to form a normal L ⁇ -phase, particularly to surfactants in the H-phase
  • the H-phase comprises surfactant molecules arranged to form cylindrical rods of indefinite length It exhibits hexagonal symmetry and a distinctive texture under the polarising microscope Typical H-phases have so high a viscosity that they appear to be curdy solids H-pha- ses near the lower concentration limit (the L-i/H-phase boundary) may be pourable but have a very high viscosity and often a mucous-like appearance Such systems tend to form expanded L ⁇ -phases particularly readily on addition of sufficient electrolyte.
  • L ⁇ -phases are described in more detail in EP 530 708. In the absence of suspended matter they are generally translucent, unlike dispersed lamellar or spherulitic phases, which are normally opaque. They are optically anisotropic and have shear-dependent viscosity. In this they differ from l_i-phases, which are micellar solutions or microemulsions. L 1 - phases are clear, optically isotropic and are usually substantially Newtonian. They are unstructured and cannot suspend solids.
  • Lrphases exhibit small angle x-ray diffraction spectra which show evidence of hexagonal symmetry and/or exhibit shear dependent viscosity.
  • Such phases usually have concentrations near the l-VH-phase boundary and may form expanded L ⁇ -phases on addition of electrolyte.
  • electrolyte In the absence of any such addition of electrolyte they lack the yield point required to provide suspending properties, and are not, therefore, "structured systems" for the purpose of this specification.
  • Expanded L ⁇ -phases of the above type are usually less robust than spherulitic systems. They are liable to become unstable at low temperatures. Moreover they frequently exhibit a relatively low yield stress, which may limit the maximum size of particle that can be stably suspended.
  • structured surfactants require the presence of a structurant, as well as surfactant and water in order to form structured systems capable of suspending solids.
  • structurant as well as surfactant and water
  • structuralant is used herein to describe any non-surfactant capable, when dissolved in water, of interacting with surfactant to form or enhance (e.g increase the yield point of) a structured system. It is typically a surfactant-desolubiliser, e.g. an electrolyte.
  • stable, pourable, homogeneous, abrasive dishwashing compositions can be obtained by suspending solid particles of common salt in a saturated aqueous solution of said salt, and adding sufficient surfactant to form, in conjunction with said solution, a stable, pourable, solid-supporting structured surfactant system.
  • the saturated salt solution acts as a structurant, interacting with the surfactant to form a suspending system.
  • the excess salt acts as an abrasive when the liquid is applied in the undiluted form, but readily dissolves in water on rinsing.
  • the invention therefore, provides a stable, pourable, homogeneous composition
  • a stable, pourable, homogeneous composition comprising particulate, solid salt suspended in a saturated aqueous solution of said salt, and sufficient surfactant to form, in conjunction with said solution, a stable, pourable, solid-supporting structured surfactant system
  • Salt refers to an alkali metal and/or alkaline earth metal halide composition, which may comprise sodium, potassium, magnesium and/or calcium chloride, but will usually, in practice, consist at least predominantly of sodium chloride
  • the salt may contain minor amounts of the impurities commonly present in naturally occurring salt, such as other halides (e g bromide and/or iodide) and other anions (e g carbonate and/or sulphate)
  • the cationic component consists essentially of alkali metal and/or alkaline earth metal, e g more than 90%, preferably more than 95%, most preferably more than 99% by weight, based on the total weight of cations Preferably at least 40% of the cations by weight are alkali metal

  • Salt is highly soluble, i e more than 30% by weight at 25°C It is highly desirable that the solubility does not vary by a large amount over the normal range of storage temperatures, to avoid unacceptable crystal growth, and destabilisation of the surfactant structure A variation of less than 10% between 0 and 40 0 C is preferred
  • Sodium chloride meets these requirements particularly well It is also cheap, natural and a highly effective hypoallergenic biocide. We have found that cleaning compositions based on saturated brine are self-preserving. Sea salt or rock salt (halite) are very suitable.
