Definitions
- the invention relates to structured cleaning composition
- it relates to 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.
- colloidal dispersions contain particles of about 1 micron or smaller, which are prevented from sedimenting by Brownian motion. Such systems are obviously incapable of dispersing relatively coarse particles such as abrasives.
- Structured suspending systems depend on the rheological properties of the suspending medium to immobilise the particles, irrespective of size. This requires the suspendding medium to exhibit a yield point which is higher than the sedimenting or creaming force exerted by the suspended particles, but low enough to enable the medium to flow under externally imposed stresses, such as pouring and stirring, like a normal liquid. The structure reforms sufficiently rapidly to prevent sedimentation once the agitation caused by the external stress has ceased.
- 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 Three main types of structured system have been employed in practice, all involving an L ⁇ -phase, in which bilayers of surfactant are arranged with the hydrophobic part of the molecule on the interior and the hydrophilic part on the exterior of the bilayer (or vice versa).
- the bilayers lie side by side, e.g. in a parallel or concentric configuration, sometimes separated by 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 spherulites, 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 . Many structured systems are intermediate between dispersed lamellar and spherulitic, involving both types of structure. Usually systems having a more spherulitic character are preferred because they tend to have lower viscosity.
- 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 spherulites 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.
- 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-phases near the lower concentration limit (the L 1 /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 .
- 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 1 -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.
- L 1 -phases 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 1 /H-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 alkali metal and/or alkaline earth metal halide 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 alkali metal and/or alkaline earth metal halide 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. Preferably at least 40% of the cations by weight are alkali metal. We particularly prefer that at least 50%, more preferably at least 75%, most preferably at least 90% by weight of the cationic component of the salt should be alkali metal. We prefer that the alkali metal consist essentially of sodium and potassium, and that any alkaline earth metal consist essentially of calcium and magnesium. We further prefer that at least 50%, more preferably at least 70%, most preferably at least 90% by weight of the alkali metal is sodium.
- 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°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.
- Saturated brine is a very aggressive medium for surfactants and the choice of structuring surfactant is therefore rather restricted.
- surfactants with a high HLB or solubility product are suitable.
- the HLB is preferably greater than 12, more preferably greater than 15, even more preferably greater than 20, most preferably greater than 30.
- Relatively few surfactants meet these criteria, but one that does is alkyl ether sulphate, which is, fortuitously, one of the preferred surfactants for use in dishwashing formulations.
- Alkyl ether sulphates having more than one, and more preferably more than two, ethyleneoxy groups are preferred.
- the alkyl ether sulphate is preferably the product obtained by:
- the base is typically an alkali metal and/or alkaline earth metal hydroxide or carbonate, usually sodium. However, for Dead Sea salt, with its high magnesium content, a mixed sodium/- magnesium ether sulphate may be preferred.
- the base may comprise an amine, especially an ethanolamine.
- Alternative surfactants which may be used include high HLB non-ionic surfactants, such as alcohol or fatty acid ethoxylates with more than 3, preferably more than 5, most preferably more than 10 ethoxy groups. Especially preferred are those with bent chain hydrocarbon groups such as oleyl or isostearyl groups. Non-ionic surfactants may require the presence of a deflocculant, such as an alkyl polyglycoside, in order to be stable.
- Other surfactants, which may be employed according to the invention include alkyl ether carboxylates and high HLB amphoteric and zwitterionic surfactants and amine oxides.
- the proportion of surfactant required will depend on the HLB. Higher HLB generally requires more surfactant.
- the amount of surfactant is greater than 2% by weight, more preferably greater than 4%, most preferably greater than 6%, but less than 25%, more preferably less than 20%, most preferably less than 15%.
- the surfactant may also comprise minor amounts of other anionic surfactants, such as, for example, C 10-20 alkyl sulphate, e.g. C 12-18 alkyl sulphate, C 10-20 alkyl benzene sulphonate or a C 8-2o aliphatic soap, e.g. C 10-20 aliphatic soap.
- the soap may be saturated or unsaturated, straight or branched chain. Preferred examples include dodecanoates, myristates, stearates, oleates, linoleates, linolenates, behenates, erucates and palmitates and coconut and tallow soaps.
- the surfactant may also include other anionic surfactants, such as olefin sulphonates, paraffin sulphonates, taurides, isethionates, ether sulphonates, ether carboxylates, sarcosinates, aliphatic ester sulphonates, e.g. alkyl glyceryl sulphonates, sulphosuccinates or sulphosuccinamates.
- anionic surfactants such as olefin sulphonates, paraffin sulphonates, taurides, isethionates, ether sulphonates, ether carboxylates, sarcosinates, aliphatic ester sulphonates, e.g. alkyl glyceryl sulphonates, sulphosuccinates or sulphosuccinamates.
- any anionic surfactant is typically sodium but may alternatively be, or comprise potassium, lithium, calcium, magnesium, ammonium, or an alkyl or hydroxyalkyl ammonium having up to 6 aliphatic carbon atoms including ethylammonium, isopropylammonium, monoethanolammonium, diethanolammonium, and triethanolammonium.
- Ammonium and ethanolammonium salts are generally more soluble than the sodium salts. Mixtures of the above cations may be used.
- the non-ionic surfactants may typically comprise amine oxides, polyglyceryl fatty esters, fatty acid ethoxylates, fatty acid monoalkanolamides, fatty acid dialkanolamides, fatty acid alkanolamide ethoxylates, propylene glycol monoesters, fatty alcohol propoxylates, alcohol ethoxylates, alkyl phenol ethoxylates, fatty amine alkoxylates and fatty acid glyceryl ester ethoxylates.
- non-ionic compounds suitable for inclusion in compositions of the present inventtion include mixed ethylene oxide/ propylene oxide block copolymers, ethylene glycol monoesters, alkyl polyglycosides, alkyl sugar esters including alkyl sucrose esters and alkyl oligosaccharide esters, sorbitan esters, ethoxylated sorbitan esters, alkyl capped polyvinyl alcohol and alkyl capped polyvinyl pyrrolidone.
- the surfactant may comprise an amphoteric or zwitterionic surfactant.
- the former preferably comprises so-called imidazoline betaines, which are also called amphoacetates, and were traditionally ascribed the zwitterionic formula: because they are obtained by treating sodium chloracetate with an imidazoline. It has been shown, however, that they are actually present, at least predominantly, as the corresponding amphoteric linear amidoamines: which are usually obtained commercially in admixture with the dicarboxymethylated form:
- R preferably has at least 8, more preferably at least 10 carbon atoms but less than 25, more preferably less than 22, even more preferably less than 20, most preferably less than 18.
- R represents a mixture of alkyl and alkenyl groups, obtained, for example, from coconut or palm oil, and having sizes ranging from 8 to 18 carbon atoms, with 12 predominating, or a fraction of such a feedstock, such as lauryl with at least 90%C 12 .
- R 1 is preferably an alkyl or hydroxyalkyl group with 1 to 4 carbon atoms, i.e. methyl, ethyl, hydroxyethyl, propyl, isopropyl, hydroxypropyl, butyl, isobutyl or hydroxybutyl, particularly preferably hydroxyethyl.
- the zwitterionic surfactant is preferably a betaine, which typically has the formula R"R' 2 + NCH 2 COOH, where R' is an aliphatic group having 1 to 4 carbon atoms and R" is an aliphatic group having from 8 to 25 carbon atoms, preferably a straight or branched chain alkyl or alkenyl group, or more preferably a group of the formula RCONR'(CH 2 ) n , where R and R' have the same significance as before, and n is an integer from 2 to 4.
- R' is a methyl, carboxymethyl, ethyl, hydroxyethyl, carboxyethyl, propyl, isopropyl, hydroxypropyl, carboxypropyl, butyl, isobutyl or hydroxybutyl group.
- the surfactant may comprise cationic surfactants such as fatty alkyl trimethylammonium or benzalkonium salts, amidoamines or imidazolines.
