Definitions

  • the present invention is in the field of laundry compositions, in particular laundry compositions for improving the hand of a fabric.
  • microcapsules in a laundry composition to improve the hand of a fabric, wherein the microcapsules have a microcapsule wall and the microcapsule wall comprises protein polymers, polysaccharide polymers, or combinations thereof.
  • perfume components it is commonplace for a plurality of perfume components to be present in a free oil perfume composition.
  • compositions for use in the present invention it is envisaged that there will be three or more, preferably four or more, more preferably five or more, most preferably six or more different perfume components.
  • An upper limit of 300 perfume components may be applied.
  • the fabric conditioner was prepared by melting the fabric softening active at ⁇ 65 °C. Water was heated to ⁇ 40°C. The minors and fabric softening active were added with stirring. The water was then cooled slightly. The composition was then cooled to room temperature. The perfume microcapsules were then added to the compositions. 2 wt.% is based of weight of microcapsules.
  • the washes took place in a Terg-O-Tometer pot. 0.5 ml of the test fabric conditioner composition and 1 L of water were added to the tergo pot, followed by 40g of knitted cotton. The test monitors were rinsed in the liquor for 10 minutes and spun for 30 seconds. The fabrics were then hung to dry in ambient conditions.
  • Microcapsules according to the present invention provide improved relative hand value compared to conventional melamine formaldehyde microcapsules.
