  • Such ingredients include pH buffering agents, perfume carriers, hydrotropes, polyelectrolytes, anti-shrinking agents, anti-oxidants, anti-corrosion agents, drape imparting agents, anti-static agents, ironing aids, antifoams, colorants, pearlisers and/or opacifiers, natural oils/extracts, processing aids, e.g. electrolytes, hygiene agents, e.g. anti-bacterials and antifungals, thickeners, low levels of cationic surfactants such as quaternary ammonium compounds and skin benefit agents.
  • the viscosity of the laundry composition is preferably 30 to 15000 mPa.s, more preferably 50 to 1000 mPa.s, most preferably 80 to 800 mPa.s.
  • This viscosity provides the benefit that a laundry liquid can carry the ancillary composition into the laundry process.
  • the viscosity measurement can be carried out at 25°C, using a 4cm diameter 2°cone and plate geometry on a DHR-2 rheometer ex. TA instruments. In detail, the measurement can be conducted using a TA-lnstruments DHR-2 rheometer with a 4cm diameter 2 degree angle cone and plate measuring system. The lower Peltier plate is used to control the temperature of the measurement to 25°C.
  • the measurement protocol is a ‘flow curve’ where the applied shear stress is varied logarithmically from 0.01 Pa to 400 Pa with 10 measurement points per decade of stress. At each stress the shear strain rate is measured over the last 5 seconds of the 10 second period over which the stress is applied with the viscosity at that stress being calculated as the quotient of the shear stress and shear rate.
  • the liquid composition as described herein may be manufactured simply by adding the ingredients to the liquid carrier (i.e. water) with stirring.
  • the liquid carrier i.e. water
  • Ancillary laundry compositions of the invention may be added to the laundry process in either the wash or the rinse phase of the laundry process.
  • the ancillary laundry composition is added during the rinse phase of the laundry process.
  • the compositions comprise less than 4 wt. % cationic and/or anionic surfactant (i.e. 0 to 2 wt.%). Therefore, the ancillary composition alone does not deliver any detersive action, nor does it deliver fabric softening cationic surfactants.
  • the compositions are intended for use in combination with traditional laundry liquids (detergent or fabric conditioner) or powder.
  • compositions of the invention comprising castor oil versus and a control of ester quat, both at 8%wt based on total weight (wt) of composition.
  • the “suppression” of malodour signal into the headspace is compared the percentage suppression determined when compared to no treatment.
