发明名称 Process for manufacture of high density detergent granules
摘要 A process for preparing detergent agglomerates is disclosed. The process includes the steps of (a) preparing a mixture of detergent components in a mixer, and (b) agglomerating the mixture from step (a) in a moderate speed mixer to produce detergent agglomerates. The detergent components include (1) from about 20% to about 35% of a surfactant compound selected from the group consisting of anionic surfactants and acid precursors of anionic surfactants; (2) from about 0% to about 65% of a particulate phosphate builder selected from the group consisting of polyphosphate, pyrophosphate, and mixtures thereof; (3) from about 6% to about 60% of a particulate carbonate selected from the group consisting of sodium carbonate, potassium carbonate, and mixtures thereof. Further, when an acid precursor of anionic surfactant is used in (1), the amount of carbonate is at least 2 times that which is sufficient to neutralize the surfactant acid, and at least 40% of the total amount of components (2) and (3) meets a particle size specification of 97% of particles less than 50 microns and median particle size of 5 to 20 microns.
