Abstract
Powders prepared by drying a slurry and suitable for use as detergent powders or components thereof contain (or consist of) sodium carbonate and/or the sodium carbonate/sodium sulphate double salt Burkeite the crystal forms of which have been modified by means of a low level of an organic polycarboxylate. The powders are able to absorb and retain very high levels of liquid components such as nonionic surfactants.
