A solid water-soluble cake comprising: from 20% to 90% sodium alkyl sulfate (AS)/sodium alkyl benzene sulfonate (LAS), co-surfactant having a 1:1.5 to 1.5:1 ratio and from 0.5% to 25% by weight magnesium chloride. One key advantage is that the cakes of this invention have a more constant dissolution rate over a wider range of water temperatures than comparable cakes made without the MgCl.sub.2. The cakes are used in automatic toilet bowl cleanser dispensers.

Synthetic surfactant cakes with magnesium chloride

A solid cake comprising 1% to 15% free fatty alcohol and 20% to 90% buffered alkali earth metal alkyl sulfate surfactant. Perfume, dye or salt, or any combination thereof are added. The surfactant and cakes made therefrom have pH's of from about 6 to about 10. The free fatty alcohol and buffered surfactant compositions and their cakes have improved longevity and improved stability. Preferred cakes are made with coconut free fatty alcohol and buffered magnesium alkyl sulfate.
