Abstract

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 C.sub.10-20 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.
