Abstract
The present invention relates to a method of manufacturing granular detergents having good biodegradability, mildness to the skin, an appropriate breaking strength of the granules, a desired bulk density and a satisfactory free-flowability, by heating a detergent slurry and atomizing it in an ambient or cold atmosphere, wherein the detergent slurry employed is a mixture consisting of 10 to 30 wt.% of olefin sulfonate having 10 to 22 carbon atoms, 60 to 90 wt.% of sodium carbonate, sodium silicate and water and 0 to 30 wt.% of other well-known additives, and the ratio of said sodium carbonate, sodium silicate and water is in a specific range.
