Stabilized aqueous zeolite A suspensions containing a nonionic surfactant as a stabilizer and an anionic surfactant as a stabilizer auxiliary are improved by using at least one sulfated C10-20 alcohol or substituted alcohol as the stabilizer auxiliary. In a further embodiment, an acid salt may be added to the suspension to adjust the pH to below 12.

A stabilized aqueous zeolite suspension with improved stability comprising: water; zeolite A in an amount of about 20 to 50%; and a stabilizer system present in an amount of about 0.5 to 5%, said stabilizer system comprising a water-insoluble nonionic surfactant as a suspension stabilizer present in an amount of about 0.2 to 3% and an anionic stabilizer auxiliary independently present in an amount of about 0.2 to 3%; all percentages being by weight based upon the total weight of the suspension and the pH of said suspension being adjusted to about from 9 up to below 12; wherein said stabilizer auxiliary is an anionic sulfate surfactant comprising at least one water-soluble salt of at least one: (a) sulfuric acid monoester of a C10-20 primary or C10-20 secondary, straight or branched chain alcohol; (b) sulfuric acid monoester or semiester of a C10-20 primary or C10-20 secondary, straight or branched chain alcohol which has first been ethoxylated with about 1-15 mols of ethylene oxide; (c) sulfuric acid monoester of a C10-20 fatty alcohol-C2-4-alkanolamide; or (d) sulfuric acid monoester of a C10-20 fatty alcohol monogylceride.
