Process for manufacturing fatty alcohol sulfate products

A process for manufacturing improved granular fatty alcohol sulfates, said process comprising

• drying for a time varying from about 30 to about 130 minutes, in a drying chamber under vacuum, a material consisting essentially of a fatty alcohol sulfate and a solvent;
• the fatty alcohol sulfate having a total dry matter content of at least 62 wt % to 80 wt %, the remainder comprising solvent or a mixture of solvents;
• and
• mechanically mixing the material during the drying process such that granulation is effected to produce a granulated fatty alcohol sulfate having a dissolution rate of 0.01 to 0.025 gr/gr water minute at 20.degree. C. calculated on the basis of the time required to reach a clear solution of 3 wt % of the fatty alcohol sulfate in water at 20.degree. C.
