Abstract
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.
