摘要：
An organophilic clay comprising the reaction product of:
(a) a smectite-type clay;
(b) a first organic cation in an amount of from about 75% to about 150% of the cation exchange capacity of the smectite-type clay; and
(c) a second organic cation provided by a polyalkoxylated quaternary ammonium salt; wherein the second organic cation is present in an amount of from about 0.01% to about 20% by weight of the total organic cation content.
The organophilic clay finds use in non-aqueous fluid systems.
