The detergent includes from about 5% to about 80% of an inorganic carrier, from about 1% to about 90% of a detergent surfactant, and 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 DEG F. (0 DEG C.) to about 180 DEG F. (82 DEG C.).
