A bleaching powder comprising: a) at least one oxidizing agent selected from the sodium salts and potassium salts of a peroxosulphuric acid, and mixtures thereof, b) 0.1 - 15 wt.% of at least one branched fatty alcohol with 8 - 24 carbon atoms, c) 0.01 - 15 wt.% of at least one dialkyl ether with 6 to 18 C atoms in the alkyl group, d) at least one inorganic alkalizing agent which is solid at 20 °C and 1013 mbar, and e) from 0 to 8% by weight of water; wherein the total amount of oils, including components b) and c), is from about 0.2 - 20% by weight, and wherein the bleaching powder does not contain any ammonium compounds, paraffin oil, mineral oil, or silicone compounds. Preferably, the persulfate oxidising agent(s) accounts for 5 - 85 wt.% of the composition. The inorganic alkalising agent may be sodium silicate or sodium metasilicate.
