摘要：A powdered laundry detergent is provided with (a) a powder laundry detergentbase that includes an inorganic carrier and a surfactant and (b) post-added acidulant anddiscrete whitening agent particles to provide a detergent having improved cool watersolubility with bulk color deterioration caused by whitening agents being minimized. Thedetergent includes from about 5% to about 80% of an inorganic carrier, from about 1%to about 90% of a detergent surfactant, up to about 15% of an acidulant and up to about30% of the discrete whitening agent particles. The acidulant is selected from the groupof acids that in an acid form are soluble in water in an amount not greater than about0.7% by weight at 25° C. and in a salt form are soluble in water at least in an amount ofabout 15% by weight at 25° C. The whitening agent particles include a whitening agentand a surfactant. The whitening agent surfactant can consist of those anionics, nonionics,zwitterionics, ampholytics, cationics, and mixtures thereof that are solids in a temperaturerange of from about 32° F. (0° C.) to about 180. degree. F. (82° C.).
