Definitions

  • the invention relates to a novel type of structured surfactant system.
  • the novel system is especially suitable for suspending pearlising concentrates for incorporation into liquid formulations such as shampoos and toiletries to import a nacreous iridescence which is attractive to consumers, and can mask inhomogeneities in the formulations.
  • Structured surfactant systems have the ability to suspend solid particles indefinitely in a pourable liquid. While the system is at rest it behaves like a solid gel holding the particles immobile, but the shear forces associated with pouring break the structure causing the suspension to flow like a mobile liquid.
  • Known structured surfactant systems are either opaque interspersions of a surfactant mesophase with an aqueous phase or cloudy opalescent lamellar phases.
  • Pearlisers typically comprise small, thin, transparent platelet crystals which can be suspended in a parallel configuration. When so suspended light falling on the crystals undergoes complex multiple reflections within the substrate similar to those which occur in a pearl and giving rise to similar optical interference effects.
  • Natural pearls comprise alternate layers of calcium carbonate and protein.
  • Artificial pearlisers include guanine/hypoxanthine crystals extracted from fish scales, mica, various salts of lead, zinc, mercury and bismuth (e.g. bismuth oxychloride). titanium oxide and various fatty acid derivatives such as magnesium stearate. coconut monoethanolamide, ethylene glycol distearate and ethylene glycol monostearate. Fish scale extracts are too expensive and the inorganic pearlisers are either too toxic for general use in toiletries e.g. lead, mercury, or relatively ineffective e.g. bismuth. The fatty acid derivatives are therefore now the most widely used pearlisers. In addition to the chemical nature and physical form of the pearliser the manner in which it is suspended has an important effect on it's visual impact. Difficulty is sometimes encountered obtaining the desired effect when incorporating pearlisers into aqueous formulations.
  • fatty acid derived pearlisers are supplied as solids which are usually added to a heated formulation above their melting point and recrystallised in situ.
  • the conditions of crystallisation and especially the amount and nature of the agitation applied must be carefully controlled in order to obtain an acceptable result. This makes it difficult to obtain consistent effects and renders solid pearlisers inconvenient to use.
  • protolamellar phase is apparently unique in being clear and optically isotropic while exhibiting the suspending properties of a structured surfactant system.
  • protolamellar phases comprise oblate (disc) micelles which can adopt a parallel lamellar-like orientation. They may typically be identified by placing them between crossed polarisers and applying stress, e.g. by tapping or shaking, when flashes are observed as the system transiently forms an anisotropic structure.
  • compositions are particularly useful because the preferred surfactant, alkyl ether sulphate, is the most commonly used ingredient of shampoo formulations on account of it's skin mildness and comparatively good foaming properties.
  • the concentrate can be included in shampoo formulations without introducing anything extraneous to the formulator's requirements.
  • the optical clarity of the protolamellar phase permits the pearlescent effect to be clearly observed without being obscured by surfactant structures as occurs when any hitherto known structured surfactant is used.
  • alkyl ether sulphates or similar water soluble surfactants are dissolved in water at relatively low concentrations they form a clear micellar solution (LI phase) with the surfactant molecules arranged in spherical clusters (micelles).
  • the aligned rod micellar or protohexagonal system is optically clear, pourable and may exhibit a hexagonal symmetry when examined by small angle x-ray diffraction (SAX), giving a first order peak of momentum transfer vector Q ⁇ , and, if the system is sufficiently well defined, one or more, progressively smaller, higher order peaks at Q values in the ratios:
  • SAX small angle x-ray diffraction
  • the length of rods increases indefinitely and the immobile M phase is formed. This is typically observed at concentrations of about 30% by weight surfactant.
  • the M phase also shows SAX peaks in the ratios characteristic of hexagonal symmetry. It typically resembles a curdy or gelatinous solid or very viscous mucous like fluid.
  • the normal lamellar, or G phase is typically formed when the concentration of the alkyl ether sulphate is increased to about 55 to 60% by weight. It is a mobile, birefringent liquid crystal with sheer dependent viscosity and lamellar symmetry, revealed by SAX peaks with the characteristic ratios
  • Our invention further provides a suspension of solid particles in an aqueous surfactant, wherein said surfactant is in a protolamellar phase.
  • the suspended particles comprise particles of a pearliser.
  • the surfactant is preferably a Cjo-is alkyl or alkenyl 1 to 10 mole ethoxy sulphate more usually a C ]2 _ 14 alkyl ethoxy sulphate and preferable an alkyl 1 to 5 mole ethoxy sulphate.
  • the ether sulphate may be a mixed propoxy ethoxy sulphate or alkyl glyceryl or alkyl glyceryl polyethoxy sulphate.
  • the cation of the alkyl ether sulphate is preferably sodium but may be potassium, lithium, ammonium, or a C] -6 amine such as an alkanolamine.
  • the surfactant may comprise minor amounts of other surfactant, especially anionic, non-ionic or amphoteric surfactants, for example alkyl sulphates, alkyl benzene sulphonates, paraffin sulphonates, olefin sulphonates, alkyl sulpho-succinates, soaps, taurides, isethionates, alkyl ethoxylates, fatty acid ethoxylates, alkyl glyceryl ethoxylates, alkyl carbohydrate ethoxylates, anine oxides or betaines.
  • anionic, non-ionic or amphoteric surfactants for example alkyl sulphates, alkyl benzene sulphonates, paraffin sulphonates, olefin sulphonates, alkyl sulpho-succinates, soaps, taurides, isethionates, alkyl ethoxylates,
  • the electrolyte is preferably sodium chloride, but could be, for example, sodium carbonate, sodium citrate, sodium tripolyphosphate, sodium hydroxide or any other salt or base which tends to salt alkyl ether sulphates out of solution.
  • the cation of the electrolyte may be sodium, potassium lithium, ammonium or, less preferably, an amine such as alkanolamine or a mixture of any of the foregoing.
  • electrolyte and of auxiliary surfactant may be conditioned by what ingredients the formulator, to whom the concentrate is to be supplied, wishes to include in the end formulations, or can tolerate.
  • the surfactant is used in a total concentration which, in the absence of electrolyte, would correspond to a clear Lj phase or protohexagonal phase.
  • the electrolyte-free surfactant/water system would be unstructured or would exhibit hexagonal symmetry under SAX.
  • concentrations required vary with different surfactants but are generally in the range 17 to 30% based on the total weight of the composition, more usually 19 to 28%.
  • the amount of electrolyte is sufficient to convert the ether sulphate/water mixture from an optically isotropic, clear, ⁇ phase or a protohexagonal phase exhibiting hexagonal symmetry to a clear, protolamellar phase, typically exhibiting lamellar symmetry, under SAX.
  • the amount required will depend on the nature and concentration of the surfactant. Typically it will be between 1 and 10% based on the total weight of the composition, more usually 2 to 5%. Sodium citrate is more expensive than sodium chloride and is most effective at concentrations of 4 to 10% but permits higher loading of pearliser.
  • the pearliser may be any of those previously discussed herein including natural pearl and inorganic pearlisers but is preferably a fatty acid derivative especially a mixture of ethylene glycol distearate and ethylene glycol monostearate.
  • the pearliser may be dispersed in the aqueous structure surfactant system e.g. by gently stirring, but in the case of the fatty acid derivatives are preferably prepared in situ by heating above their melting point, e.g. temperatures between 65 and 80 ⁇ 0, dispersing the liquid pearliser in the structured surfactant system, preferably with sufficient stirring to form droplets of from 1 to 60 microns, e.g. 15 to 50 microns, and cooling to ambient temperature. Preferably cooling is relatively slow e.g. the mixture is allowed to cool naturally.
  • the amount of pearliser can be varied considerably, the main constraint on the upper limit being the viscosity.
  • the amount of pearliser should not be so high as to render the product unpourable, or unacceptably viscous.
  • the pearliser is present in amounts greater than suspending surfactant.
  • pearliser may be present in amounts ranging from 5% up to about 60% e.g. 10 to 45% more preferably 15 to 30%, especially 18 to 28% of the total weight of the mixture.
  • the ration of pearliser to surfactant is preferably from 0.6 to 2 e.g. 1.2 to 1.3 by weight.
  • Ancillary ingredients suitable for inclusion in toiletries could in principle be included, but are usually omitted to avoid unduly constraining the customer with regard to its freedom to formulate. However, it is generally desirable to include small amounts of preservative, such as formaldehyde or other microbiocidally and/or fungicidally active material.
  • the novel structured, protolamellar phase may be used to suspend solids other than pearliser, e.g. builders such as zeolite or phosphate for use in detergent.
