Abstract
Crude vegetable oil is dewaxed by admixture with a mixture of surfactants comprising an aqueous solution of less than 100 ppm of a sulfosuccinate alkyl ester such as dioctyl sodium sulfosuccinate and 0.01 to 0.5% of a fatty acid sulfate such as sodium lauryl sulfate. The oil is then centrifuged and washed. The oil can be simultaneously degummed by the addition of a phosphate compound to the treatment liquid.
