Abstract

The present invention relates to a cationic particle containing an aqueous cationic surfactant solution adsorbed to a water-insoluble high absorbing material. Preferably, the water-insoluble high absorbing material has an oil absorption (using d-butyl phthalate) of from about 140 mL/100 g to about 400 mL/100 g. A process for making the cationic particle is also described herein. The cationic particle can be incorporated into a particulate detergent composition.
