Abstract

A process for stabilizing an aqueous zeolite suspension by adding to the suspension at least one nonionic surfactant comprising an alkyl or alkenyl glycoside of the formula R.sup.3 O--(G).sub.x in which R.sup.3 is an alkyl or alkenyl group containing 6 to 22 carbon atoms, G is a glycose residue of a sugar containing 5 or 6 carbon atoms and x is a number of 1 to 10. Only nonionic surfactants are added to the suspension to stabilize the suspension. The suspension may be stabilized by addition of the alkyl or alkenyl glycoside in combination with nonionic surfactant such as a Guebert alcohol polyethylene glycol ether or a fatty alcohol polyethylene glycol ether.
