Abstract (en)
[origin: WO9316159A1] Disclosed is method of stabilizing aqueous zeolite suspensions by adding fatty-alcohol poly(ethylene glycol) ethers of the formula (I): R?1O-(CH2?CH2?O)n?H, in which R?1 is an aliphatic alkyl or alkenyl group with 12 to 18 carbon atoms and n is a number from 4 to 7.
