Summary In the caustic refining of vegetable oils using liquid‐mixing the concentration of caustic solution required, the amount of excess caustic used, the length of time of mixing the oil‐soapstock mixture in the cold, and the oil content of the soapstock are governed by the amount and kinds of phosphatides present in the oil. In the mist‐mixing process of refining vegetable oils using caustic, the mixing time is kept constant, the concentration of the caustic is kept constant for a particular kind or type of oil, the excess caustic is kept constant for a particular kind or type of oil, and the oil content of the soapstock is governed by the amount and kinds of phosphatides present in the oil, and by the use of sodium silicate.
