  • Patent number: 5854198
    Abstract: In order to enhance the stability of sodium percarbonate bleach in particulate detergent compositions, crystalline aluminosilicate and a water-soluble alkali metal silicate in an amount of from 1-20% by weight based on the aluminosilicate are included in the non-spray dried base powder. In order to obtain the stabilizing effect, the crystalline aluminosilicate comprises zeolite MAP or the alkali metal silicate is homogeneously dispersed with respect to the aluminosilicate.

  • Patent number: 5789535
    Abstract: Methods of preparing granules which contain a water soluble or water dispersable polymer suitable for use in detergents are disclosed, in which a solution of the polymer in a liquid or a dispersion of the polymer in a liquid is formed into granules, in a single drying and granulation stage, wherein the polymer solution or dispersion is introduced into a substantially horizontal drum containing a multiplicity or rotating arms proximate its internal surface, which internal surface has an elevated temperature, and a gas is introduced into the drum at an elevated temperature via a gas inlet. Granules prepared by such methods may be used in detergent compositions, water treatment compositions, agrochemical compositions, adhesive compositions and cosmetic compositions, and may be used as pigment dispersants, mineral dispersants, cement additives, oil field additives, textile additives and paper additives.
