  • EP 254653 (Cotelle SA and Henkel: 1986) relates to dilution-thickening concentrates in general and covers compositions which are thickened with excess NaCl.
  • WO 95/02664 (Jeyes Group: 1993) discloses a liquid concentrate for dilution with water to give a thickened product.

  • compositions disclosed in the above-mentioned documents can be sold as concentrates and are intended for dilution before use to give a thickened composition.
  • Such rheological properties are considered advantageous for the cleaning of hard surfaces as they prevent the product running off the surface.
  • shampoo compositions it is also advantageous for the product to thicken in the presence of water such that it is not washed of the skin rapidly.
  • compositions useful for this purpose may take the form of gels or pastes and may be applied to the surface of the articles with a cloth or sponge.
  • adsorbent carrier includes articles such as a cloth or sponge. The operative consideration is that the carrier can be used to carry the washing solution to the articles to be cleaned.
  • the present invention provides a cleaning process which comprises the steps of:
  • a dilution thickening composition in combination with a carrier causes the surfactant to be retained on the carrier and released over a significantly longer period of time. Therefore in the method of the present invention the increased viscosity on dilution of selected compositions is beneficially combined with the delivering features of a porous substrate to extend the working lifetime of the substrate during the cleaning process
  • the present invention also provides a kit of parts comprising:
  • the compositions of the present invention comprise at least one surfactant whose solution viscosity is strongly influenced by the prevailing electrolyte concentration. While other means by which the viscosity can be increased on dilution are known, the use of an electrolyte is preferred.
  • the thickening of the diluted concentrate is effected by the presence of selected 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 reduced and the surface active agent component is then capable of exerting its thickening effect.
  • the carrier which is preferably a sponge
  • the carrier is treated with the surfactant composition either by dipping at least a part of the carrier in the composition or by otherwise exposing the carrier to the surfactant composition, such as by pouring or otherwise dispensing the surfactant composition onto the carrier.
  • the combination of the carrier and the composition is treated with water, either by dipping the combination into water or by the simple expedient of starting with a wet carrier.
  • the electrolyte concentration falls below that which is sufficient to prevent the surfactants from thickening and the viscosity of the surfactant composition rises.

Abstract

La présente invention concerne les améliorations apportées au nettoyage léger et en particulier aux améliorations se rapportant au lavage de vaisselle manuel. L'invention consiste en un procédé comportant les étapes suivantes: a) traitement d'un support absorbant tel qu'un chiffon ou de préférence une éponge avec une composition surfactante susceptible de s'épaissir au contact de l'eau, b) traitement de la combinaison du support et de la composition surfactante avec de l'eau, et c) après l'étape (b) effectuer un nettoyage avec le support. L'avantage de ce procédé réside en ce que la composition surfactante s'épaissit à l'intérieur du support et y est retenue afin de fournir une libération prolongée du surfactant à partir du support.
