Definitions

  • the present invention relates to liquid detergent compositions , especially compositions which contain a silicone , a cationic polymer and an anionic surfactant .
  • Liquid detergent compositions comprising surfactants are known .
  • Such compositions can be used, for example, for cleaning laundry, for example for cleaning fine- fabrics or for heavy-duty laundry cleaning .
  • Liquid laundry detergent compositions that contain silicones are known. Silicories are used as they provide the fibres of the fabric with lubricity leading to improved performance in terms of softness, elasticity, drape, wrinkle resistance etc. However, typically silicones are not effectively deposited onto the textile fibre during the washing process, much of the silicone is washed away. A number of solutions to this problem have been suggested.
  • O0218528 discloses liquid detergent compositions of the type marketed as Ariel Style and describe silicones derivatised to be positively charged (cationic) during the wash and, therefore, more substantive to natural fibres. Typically low or zero amounts of anionic surfactant are used due to low product stability caused by the incompatibilities of the cationic silicone with the anionic surfactant, leading to a reduction in cleaning performance.
  • the formulator will avoid ttie inclusion of anionic surfactants to avoid any incompatibilities with cationic silicone needed in the composition.
  • a reduction or elimination of anionic surfactants may lead to a fall in cleaning performance of the composition against greasy stains and a rise in cost, due to the need to include large amounts of expensive nonionic surfactants, or other adjuncts to aid cleaning performance.
  • the inclusion of larger amounts of non-cationic silicones is possible but is wasteful and expensive .
  • composition that allocs the inclusion of a significant amount of anionic surfactant and effective amount of a silicone, preferably a silicone that is not cationic .
