A preactivated organophilic clay gellant that may be used to thicken organic compositions, especially, lubricating greases without the presence of a polar activator. The preactivated organophilic clay gellant may be prepared using certain process parameters namely shearing of the smectite-type clay prior to reaction with the organic cation, dilute reaction conditions and gentle drying of the organophilic clay or the preactivated organophilic clay gellant. |
