ABSTRACT:
The present invention relates to a detergent auxiliary composition comprising: (i) a liquid or liquefiable active component; and (ii) a water-insoluble solid support component and (iii) a water-soluble and/or water dispersible encapsulating material; and (iv) optionally one or more adjunct components, characterised in that the composition further comprises (v) a surface deposition enhancing cationic polymer or oligomer having cationic groups such that fewer than 50% are de-activated when a 1% by weight solution of the polymer or oligomer (prepared in deionised water and then adjusted to pH 7.0 with sodium carbonate or citric acid) is stored at 25° C. for ten days (ten day storage test), wherein the surface deposition enhancing cationic polymer is adsorbed onto the water-insoluble solid support component, and wherein the water-soluble and/or water dispersible encapsulating material encapsulates the liquid or liquefiable active component, the water-insoluble solid support component and the surface deposition enhancing cationic polymer.
