  • Such systems are known from WO 2004/069979 which discloses particular combinations of cationic polymers and anionic surfactants.
  • WO 2008/022838 discloses liquid laundry compositions comprising anionic surfactant, nonionic surfactant, fatty acid and cationic polymers. The compositions are stated to provide both effective softening and cleaning.
  • this invention is directed to a liquid detergent composition

  • the weight ratio of (a) to (b) is from 1.25:1 to 2.25:1 , and wherein the total level of surfactant present in the composition is at least 25 wt.%.
  • this invention is directed to a method for the provision of softness to a textile, comprising the steps:
  • the term “comprising” means including, made up of, composed of, consisting and/or consisting essentially of.
  • a formula shall be considered physically "stable" when after 1 week at 21 degrees Celsius it exhibits no signs of phase separation.
  • the present invention is directed to laundry compositions containing fatty acid or salt thereof, a polysaccharide-based cationic polymer, a non-ionic surfactant and an anionic surfactant, wherein the ratio of nonionic to anionic surfactant is from 1.25:1 to 2.25:1 , and wherein the total level of surfactant is at least 25 wt.%.
  • the composition delivers a high level of softening to fabrics in comparison to the prior art.
  • the composition also displays excellent stability.
  • Softening includes, but is not limited to, an improvement in the handling of a garment treated with the compositions of this invention relative to that of an article laundered under identical conditions but without the use of this invention. Consumers will often describe an article that is softened as “silky” or “fluffy”, and generally prefer the feel of treated garments to those that are unsoftened.
  • compositions of these compositions are not limited to just softening, however. They may, depending on the particular embodiment of the invention selected, also provide an antistatic benefit.
