Fluids are provided which resist phase separation by inclusion of a stabilizing amount of a glutamic acid derivative in the presence of ethanol. The fluids comprise an aqueous discontinuous phase, a silicone oil containing continuous phase, a glutamic acid derivative such as dibutyl ethylhexanoyl glutamide, and ethanol. The fluids may be prepared without heating to solubilize the glutamic acid derivative本發明提供一種藉由在乙醇存在下併入安定化用量之麩胺酸衍生物以阻抗相分離之流體。該等流體包括水性不連續相、含聚矽氧油連續相、諸如二丁基乙基己醯基麩胺醯胺之麩胺酸衍生物及乙醇。可在無需加熱溶解該麩胺酸衍生物下製備該等流體。
