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 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.).
Abstract: A powdered laundry detergent is provided with (a) a powder laundry detergent base that includes an inorganic carrier and a surfactant and (b) post-added acidulant and discrete whitening agent particles to provide a detergent having improved cool water solubility with bulk color deterioration caused by whitening agents being minimized. The detergent 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 about 30% of the discrete whitening agent particles. The acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 0.7% by weight at 25.degree. C. and in a salt form are soluble in water at least in an amount of about 15% by weight at 25.degree. C. The whitening agent particles include a whitening agent and a surfactant.
Abstract: A process for preparing discrete whitening agent particles that includes the steps of providing a whitening agent, admixing a surfactant that is a solid in a temperature range of from about 32.degree. F. (0.degree. C.) to about 180.degree. F. (82.degree. C.) with the whitening agent to form a substantially homogenous mass, and forming the mixture into discrete particles. The particles are preferably formed by extruding the homogeneous mass through an extruder at an elevated temperature. The particles may be added to a powder detergent.
Abstract: An whitening agent particle includes a whitening agent and a surfactant, wherein the surfactant is selected from the group consisting of 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 particle may be added to a powder detergent.
Abstract: A method for producing polysuccinimide is provided. Thermal polymerization of maleamic acid at a temperature of from about 160.degree. C. to about 330.degree. C. produces polysuccinimide. The reaction is optionally conducted in the presence of one or more processing aids, solvents or diluents. The polysuccinimide is particularly useful as a detergent additive.
