| 主权项 | 1. An organophilic clay comprising a smectite clay comprising exchangeable cations modified by reaction with a protonated amphoteric surfactant, wherein the protonated amphoteric surfactant is substituted for an amount in the range of from about 25% to about 100% of the exchangeable cations, wherein the organophilic clay is present in a fluid comprising an oil and wherein the protonated amphoteric surfactant does not comprise a quaternary ammonium surfactant. | ||
