ABSTRACT:
A powdered laundry detergent is provided with discrete whitening agent particles that do not adversely affect the bulk appearance of the detergent during storage. The detergent includes from about 5% to about 80% of an inorganic carrier, from about 1% to about 90% of a detergent surfactant, and from 0.1% up to about 30% of the discrete whitening agent particles. The whitening agent particles include a whitening agent and a surfactant. The surfactant for the whitening agent particle includes those anionics, nonionics, zwitterionics, ampholytics, cationics, and mixtures thereof that are solids in a temperature range of from about 32.degree. F. (0.degree. C.) to about 180.degree. F. (82.degree. C.). The whitening agent particles, in a more desirably form, include a whitener and water. The particles are formed by extruding a homogenous mass into discrete particles. The homogenous mass includes either a whitening agent, a surfactant, and optionally a plasticizer or a whitening agent and water.
