<p>Solid surfactant cake compositions are disclosed which incorporate certain solubility reducing materials. The surfactant is an anionic surfactant selected from the organic sulfates and sulfonates. The solubility reducing agent is preferably selected from the group consisting of: and wherein R' is methyl or ethyl and R is selected from: (1) ¢m.n.o!bicycloalkane derivatives having the following skeletal structure: wherein m is from 2 to 3, n is from 1 to 2 and o is from 1 to 2, and wherein a nonbridgehead site of said R moiety is attached to the balance of the molecule; (2) a derivative of ¢4.4.0! trans-decalin having the following skeletal structure: wherein a nonbridgehead site of said R moiety is attached to the balance of the molecule; (3) a derivative of cyclohexane having the following skeletal structure: wherein R1, R2 and R3 are each selected from an ethyl, methyl or propyl moiety, and wherein the balance of the molecule is attached to the 2, 3, 4, 5 or 6 position of the cyclohexane ring of said R moiety; or (4) an n-nonyl moiety. The solubility reducing agent may also be a compound having the following structure: The composition has utility as a solid surfactant cake which may be placed in a toilet tank dispenser to distribute a surfactant and other ingredients to a toilet bowl when the toilet is flushed.</p> |
