Definitions

  • This invention is concerned with improvements in and relating to liquid compositions and, more especially, to concentrates for dilution, with water, to produce liquid surfactant-containing compositions.
  • the surfactant-containing compositions with which the invention is concerned are liquid compositions intended for application to a surface to bring a surfactant into contact with that surface, for example to cleanse it by detersive action and/or by germicidal or disinfectant action, or to condition it.
  • the present invention is concerned with compositions containing surface active agents as active ingredients and, also, with compositions containing other principal active ingredients, e.g. disinfectants or bleaching agents.
  • the invention is thus, for example, concerned with cleansing compositions for application to hard surfaces such as sinks, washbasins, baths, toilet bowls, walls or floors.
  • the invention is also concerned with compositions for application to soft surfaces such as fabrics, skin or hair, and may, thus, take the form of a shampoo, conditioner, hand soap or like product. It is well known to provide so-called “thick” cr “thickened” liquids compositions, that is compositions with generally increased viscosity, for application to hard surfaces.
  • Thickened compositions have the advantage that, by virtue of their viscosity, they tend to remain in contact with vertical or inclined surfaces for a longer period of time than do more mobile compositions. Thickened compositions may also be poured in a controlled manner and are generally aesthetically appealing.
  • liquid cleansing or like compositions such as fabric softener compositions
  • precursors for liquid cleansing or like compositions such as fabric softener compositions
  • liquid concentrates to be diluted with water, to the desired concentration, by the user.
  • thick concentrates become thinner, ie. reduce in viscosity.
  • a liquid concentrate for a thickened composition may be formulated in such a manner that its viscosity remains the same or,preferably, increses on dilution with water, e.g. when diluted with water in a ratio of water to concentrate of at least 1:1, the product still has an acceptable viscosity, e.g. 50 cp or more at 25°C.
  • a liquid concentrate for dilution with water to give a liquid composition which concentrate, on dilution with water, contain the same viscosity, or increases in viscosity; the concentrate containing, as thickening component, (i) a surface active component consisting of an ether sulphate surface active agent alone or in admixture with another anionic surface active agent or a nonionic or amphoteric surface active agent, or a cationic surface active agent alone or in admixture with a nonionic surfactant; and (ii) an electrolyte and/or hydrotrope.
  • the concentrates of the invention by virtue of their relatively low initial viscosity, are readily miscible with water whereby to more easily obtain a uniform end product.
  • the thickening of the diluted concentrate is effected by the presence of the specified surface active agents whose thickening effect, in the concentrate, is reduced by the presence of an excess of dissolved electrolyte.
  • the concentration of dissolved electrolyte is, of course, reduced and the surface active agent component is then capable of exerting its thickening effect.
  • Suitable ether sulphates which may be used in accordance with the invention may be represented by the formula: R 1 - O - ( - CH 2 - CH 2 - 0) n S0 3 M
  • R is an alkyl group containing from 8 to 20 carbon atoms, preferably from 10 to 14 carbon atoms
  • M is eg. an alkali metal, ammonium or alkylolamine, cation, especially a sodium cation
  • n is an integer from 1 to 6, preferably 2 to 4.

  • One particular class of non-ionic surfactants for use in combination with the ether sulphate surface active agents comprises the amine oxides of the formula:
  • R is a long chain alkyl group, typically containing 8 to 20 carbon atoms; and each of the groups R is a lower alkyl group, typically containing 1-4 carbon atoms.
  • R is a long chain alkyl group, typically containing 8 to 20 carbon atoms; and each of the groups R is a lower alkyl group, typically containing 1-4 carbon atoms.
  • This class of non-ionic surfactants are alkyl dimethyl amine oxides such as sold under the trade name "Empigen OB" by Albright & Wilson.

  • the nonionic surfactants for use in combination with the cationic surfactant may be a nonionic surfactant as described above for use in combination with the ether sulphates.
  • the concentration of the surfactant component in the concentrate depends upon two principal factors, (i) the concentration of surfactant component required to give a thickened end product of the desired viscosity and (ii) the degree of dilution contemplated.

  • the electrolyte used in the composition will typically be sodium chloride (which is in itself a component of one important cleansing agent, sodium hypochlorite bleach) but, of course, other water-soluble electrolytes may be employed, including builders such as sodium, sodium phosphates and alkali metal silicates.
  • the amount of electrolyte required to give the desired effect is something which may be established by simple experimentation but, in general, it has been found that concentrations, in the concentrate, of about 10% by weight or more are useful, typically giving rise to final concentrations of about 3.5% by weight or more.
