Abstract:
1. A detergent auxiliary particle comprising: (i) a liquid or liquefiable active component; (ii) a water-insoluble solid support component; (iii) a water-soluble and/or water-dispersible encapsulating material; and (iv) optionally one or more adjunct components, wherein the particle further comprises (v) a surface deposition enhancing cationic polymer or oligomer having cationic groups provided by cyclic amine groups, such that fewer than 50% of the cationic groups 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 at least part of, the surface deposition enhancing cationic polymer or oligomer is adsorbed onto the water-insoluble solid support component, and wherein the water-soluble and/or water dispersible encapsulating material encapsulates at least part of, the liquid or liquefiable active component, the water-insoluble solid support component and the surface deposition enhancing cationic polymer.
