DETAILED DESCRIPTION I claim: 1. An organoclay slurry comprising from about 20% to about 50% by weight of an organophilic clay, from about 50% to about 80% by weight of an aqueous solution of a low molecular weight polar organic compound wherein the concentration of said compound is from about 2. 5% to about 97. 5% by weight of said solution, and from 0% to about 40%, based on the weight of said organophilic clay, of an alkali metal base selected from the group consisting of sodium carbonate, potassium carbonate, ammonium carbonate, and mixtures thereof, wherein said solution contains: (a) from about 20% to about 65% methanol when said compound is methanol; (b) from about 10% to about 65% ethanol when said compound is ethanol; (c) from about 2. 5% to about 50% of an alcohol containing three carbon atoms when said compound is said alcohol; (d) from about 2. 5% to about 35% of an alcohol containing four carbon atoms when said compound is said alcohol; and (e) from about 2. 5% to about 20% of an alcohol containing five carbon atoms when said compound is said alcohol. 2. The slurry of claim 1 wherein said compound is selected from the group consisting of alcohols containing from 1 to 6 carbon atoms, ketones containing from 3 to 5 carbon atoms, nitroalkanes containing from 1 to 3 carbon atoms, alkylene carbonates containing from 3 to 5 carbon atoms, amides containing from 1 to 4 carbon atoms, nitriles containing from 2 to 4 carbon atoms, esters containing from 2 to 4 carbon atoms, and mixtures thereof. 3. The slurry of claim 1 wherein said aqueous solution contains from about 20% to about 65% of methanol. 4. The slurry of claim 1 wherein said aqueous solution contains from about 10% to about 65% of ethanol. 5. The slurry of claim 1 wherein said aqueous solution contains from about 2. 5% to about 50% of an alcohol containing three carbon atoms. 6. The slurry of claim 1 wherein said aqueous solution contains from about 2. 5% to about 35% of an alcohol containing four carbon atoms. 7. The slurry of claim 1 wherein said aqueous solution contains from about 2
