Abstract

Abstract Powder-form washing and cleaning agents which can be made up into stock liquors containing in addition to synthetic surfactants and ingredients such as alkali carbonates, alkali silicates, alkali sulfates, water-soluble, organic or inorganic complexing agents, (a) from 10 to 40% by weight of finely particulate zeolites of the NaA or NaX type or mixtures thereof and (b) from 0.5 to 2.5% by weight of xanthan gum as dispersant in a ratio by weight of a:b of from 5:1 to 25:1 for the preparation of approximately 10% by weight aqueous stable stock liquor suspensions.
