PCT No. PCT/EP93/00227 Sec. 371 Date Aug. 10, 1994 Sec. 102(e) Date Aug. 10, 1994 PCT Filed Feb. 1, 1993 PCT Pub. No. WO93/16159 PCT Pub. Date Aug. 19, 1993.A method for stabilizing aqueous zeolite suspensions by adding fatty-alcohol poly(ethylene glycol) ethers of the formula R1O-(CH2CH2O)n in which R1 is a linear aliphatic alkyl group containing 12 to 14 carbon atoms and n is an average number of from 4.2 to 4.8. Aqueous slurries containing from 20 to 60% by weight of zeolite are stabilized by adding it to the slurry from 0.1 to 5% by weight of the fatty-alcohol poly(ethylene glycol) ethers.
