Definitions

  • the present invention relates to coloured perfumed speckles for use in granular laundry detergent compositions and a process for making them.
  • perfume is added to improve aesthetic appeal by imparting a pleasing odour both during storage and in use. Additionally it may impart a pleasing odour to the washed fabrics.
  • perfumes are highly volatile and the amount remaining on the washed clothes by the end of the washing process is usually a small fraction of that which was added at the beginning.
  • WO 9734981 discloses a porous zeolite into which the perfume is absorbed and trapped by a release inhibitor which hydrolyses during the wash thereby releasing the perfume in a controlled manner.
  • WO 9842818 discloses a porous core particle encapsulated in a glassy material and coated in a water-soluble or dispersible compound. Preferably a perfume is supported or contained within the porous carrier.
  • EP 466235 discloses a process of combining a perfume with one or more non-ionic emulsifiers to form a non-aqueous phase which is then mixed with an aqueous phase to form a structured emulsion containing liquid-crystal structures.
  • the emulsified perfume is added to a detergent powder and is said to enhance perfume delivery and possibly deposition.
  • US 5 605 883 discloses a colourant speckle which exhibits reduced spotting of teated fabrics. It also states that the speckle may be used as a vehicle for carrying cosurfactants, enzymes, oxidants, bleach activators and fragrances .
  • US 4 097 418 discloses a granular coloured speckle having reduced staining properties and may comprise up to 3% of enzymes, bleaching agents, antimicrobial agents, corrosion inhibitors and perfume.
  • the delivery of perfume may be significantly enhanced and prolonged if the perfume is included in coloured speckles.
  • Especially advantageous perfume delivery can be achieved if the perfume is incorporated in the speckles in aqueous emulsion form.
  • the colouration of the speckles may provide an association with the enhanced perfume delivery in the mind of the consumer, thus reinforcing the consumer's appreciation of the wash process.
  • the present invention provides a perfumed coloured granular composition for use as speckles in a particulate laundry detergent composition which comprises at least 1 wt% perfume.
  • the present invention provides a process for the manufacture of a perfumed coloured granular composition for use as speckles in a particulate laundry detergent composition, comprising the steps of:
