    Abstract: The density of a spray-dried, phosphate-reduced detergent powder containingA) 4 to 20% by weight of at least one anionic surfactant,B) 2 to 20% by weight of at least one nonionic surfactant,C) 20 to 50% by weight of at least one builder,D) 3 to 25% by weight washing alkalis,E) 0 to 30% by weight of other detergent constituentswhich lend themselves to hot spray drying is increased by continuously introducing a detergent powder having up to 50% of the final amount of nonionic surfactant into a cylindrical, horizontally arranged mixing drum in which a shaft is mounted for axial rotation. The shaft is equipped with radially arranged impact tools of defined length. The rotational speed of the shaft is regulated to provide a Froude index of from 50 to 1000.

    Abstract: A method for the production of granular sodium perborate tetrahydrate is disclosed herein. The method includes the steps of adding 0.3-5% by weight of a sodium salt or a potassium salt of a polymeric carboxylic acid to powdered perborate tetrahydrate, softening the mixture by heating under pressure to form a plastically deformable mass, deforming the plastically deformable mass into thin strands by pressing, and comminuting the strands into granular form. The perborate tetrahydrate may be de-watered to produce granular perborate monohydrate. The final granular products exhibit high abrasion resistance and are preferably used in washing and cleaning agents.
