Definitions

  • the present invention relates to fabric softening compositions that not only provide excellent fabric softening benefit but also protect the fabric, especially wool fabric, from felting.
  • the fabric softening composition contains, in addition to common ingredients found in such compositions, at least one derivatised carbohydrate thickener that is substantive to the fabric, a fabric softening silicone compound and at least one protein or derivative thereof.
  • WO-A-00/40687 describes a fabric softener including a cationic softening active, a water soluble protein, a fabric fibre-substantive thickener, a fabric softening silicone and water.
  • the object of the present invention is to provide a fabric conditioner composition which not only provides excellent fabric softening benefit but also protects the fabric, especially wool fabric, from felting.
  • Felting is the process whereby fibres, in particular wool fibres, become impossibly matted. In particular it can be a problem with the use of warm/hot "soapy water" during the washing process, which opens up the wool fibre structure. When the wool fibres are cooled in the rinse cycle this can lock the fibre structure into a matted state.
  • Clearly a product that can protect against felting, especially during the rinse cycle has a major benefit in helping garments retain their original size and finish.
  • compositions preferably have a medium to high viscosity (by medium to high viscosity we mean from 50 to 50,000 cps, preferably from 100 to 1,500 cps, as measured using a Brookfield LVT viscometer, spindle no. 2 at 12 rpm and at 20°C.
  • medium to high viscosity we mean from 50 to 50,000 cps, preferably from 100 to 1,500 cps, as measured using a Brookfield LVT viscometer, spindle no. 2 at 12 rpm and at 20°C.
  • the present invention may suitably be used for fabric comprising natural and/or man-made/synthetic fibres.
  • Such fibres can be comprised of protein (for example wool, silk), cellulose (for example linen, cotton, jute), regenerated cellulose (for example viscose, lyocell), a cellulose derivative (for example acetate, triacetate), an acrylic, a polyamide or a polyester.
