A process for improving aesthetics of a liquid dishwashing detergent product is disclosed. The process includes the steps of providing a liquid dishwashing detergent composition and adding solid particles to the liquid dishwashing detergent composition. The particles are coated with a polymeric coating. The coating is prepared from materials which are insoluble in the liquid dishwashing detergent composition but soluble in dishwashing wash solution.

A process for forming a non-staining colored composite particle suitable for incorporation in a bleach-containing or a non-bleach-containing liquid detergent composition is disclosed. The process includes the steps of forming a colored liquid dispersion of pigment particles in a first liquid medium wherein the size of the pigment particles in the colored liquid dispersion is no greater than about 5 &mgr;m. The process includes the step of mixing the colored liquid dispersion with a polymeric material and a second liquid medium to form a sprayable colored polymeric material. The process also includes the step of spraying the colored polymeric material on a composite particle and forming a colored polymeric coating on the composite particle. A non-staining colored particle and a liquid ADW detergent composition are also disclosed.
