Definitions

  • the present invention is concerned with liquid detergent compositions of the kind containing a structure formed from detergent active material, the detergent-active structure existing as a separate phase dispersed within a predominantly aqueous phase.
  • This aqueous phase usually contains dissolved electrolyte.
  • the present invention relates to liquid detergent-active structured compositions containing significant levels of nonionic detergent materials.
  • the present invention is concerned with liquid detergent compositions which are "internally structured" in that the structure is formed by primary detergent active ingredients.
  • Such structuring is very well known in the art and may be deliberately brought about to endow properties such as consumer preferred flow properties and/or turbid appearance.
  • Many detergent-active structured liquids are also capable of suspending particulate solids such as detergency builders and abrasive particles.
  • lamellar droplets are called "spherulites".
  • the presence and identity of a surfactant structuring system in a liquid may be determined by means known to those skilled in the art for example, optical techniques, various rheometrical measurements, x-ray or neutron diffraction, and sometimes, electron microscopy.
  • Electrolyte may be only dissolved in the aqueous continuous phase or may also be present as suspended solid particles. Particles of solid materials which are insoluble in the aqueous phase may be suspended alternatively or in addition to any solid electrolyte particles.
  • the suspended solid can comprise suspended solids which are substantially the same as the dissolved electrolyte, being an excess of same beyond the solubility limit This solid is usually present as a detergency builder, i.e. to counteract the effects of calcium ion water hardness in the wash.
  • the suspended solid usually comprises a particulate abrasive, Insoluble in the system. In that case the electrolyte, present to contribute to the structuring of the active material in the dispersed phase, is generally different from the abrasive compounds. In certain cases, the abrasive can however comprise partially soluble salts which dissolve when the product is diluted.
  • the structure is usually used for thickening the product to give consumer-preferred flow properties, and sometimes to suspend pigment particles.
  • compositions of the first kind are described in for example our patent specification EP-A-38,101 whilst examples of those in the second category are described in our specification EP-104,452.
  • Those in the third category are for example, described in US 4,244,840.
  • the dispersed detergent-active structure in these liquids is generally believed to consist of an onion-like configuration comprising concentric bilayers of detergent active molecules, between which is trapped water (aqueous phase).
  • These configurations of detergent-active material are sometimes referred to as lamellar droplets. It is believed that the close-packing of these droplets enables the solid materials to be kept in suspension.
  • the lamellar droplets are themselves a sub-set of lamellar structures which are capable of being formed in detergent active/aqueous electrolyte systems. Lamellar droplet systems, are a preferred category of structures which can exist in detergent liquids and are essential to the present invention.
