ABSTRACT:
An organo-clay is prepared by treating a clay mineral of the smectite type with a mixture of di(lower alkyl) arylkyl (higher alkyl) ammonium compound and a di(lower alkyl) di(higher alkyl) ammonium compound and thereafter subjecting the treated clay mineral to high shear mixing for a time sufficient to dissipate in the mixture at least 100 KJ of energy per Kg of dry solids in the mixture. The organo-clay is useful in gelling compositions containing one or more liquid aliphatic alcohols.
