Liquid detergent compositions with low-density particles

A process for reducing the density of dense, particulate, non-surfactant detergent ingredients from their initial density of about 1.7 g/cc, or greater, to a density of about 1.5 g/cc, or less, comprising the steps of:

• a) admixing said dense ingredients with water, a water-soluble binding agent and water-insoluble hollow microspheres, at a weight radio of said detergent ingredients:
• said microspheres in the range from about 1:10 to about 1:2, to form a pumpable fluid;
• b) dispersing the pumpable fluid from step (a) into a spray-dry tower as droplets;
• and
• c) evaporating the water from said droplets by contacting said droplets with hot air, said hot air being at an impinging temperature of at least about 200° C., to form hollow-core particles comprising said detergent ingredients coated on said microspheres.
