Abstract
<PICT:0636945/III/1> Soap is produced substantially free from glycerol and rancidizing factors, without the usual salting out and fitting steps, by continuously washing neat soap with a brine solution of a concentration close to the critical concentration below which the neat soap would dissolve in it. Neat soap is that soap phase between the middle and curd soap phases wherein the soap concentration is such that the soap is still liquid and is in the form of a water-in-soap dispersion. The concentration of the brine solution is preferably a little above the critical concentration and the treatment is preferably effected at a temperature of about 100 DEG C. The excess salt is then removed from the soap by washing with an alkaline lye, such as sodium hydrate lye, also having a concentration close to and preferably in excess of the critical concentration. The alkali remaining in the soap may be neutralized by addition of a fast-acting saponifiable fat, such as coconut or palm kernel oil, fatty acid or other product capable of neutralizing the free alkali while allowing the final soap product of suitable grade to be obtained. The soap without further drying is then ready for milling, moulding, &c. The alkaline lye-salt liquor may be treated to recover the lye for use in the saponification stage. A suitable plant comprises three brine washing stages E1, E2, and E3, and a final alkaline lye washing stage E0, each stage being equipped with a washing liquor supply tank r, a mixer m and a separator s. The soap path is indicated by full arrows, the glycerol being removed therefrom at B; the brine path is shown by broken line arrows commencing at C, the glycerol loaded brine being discharged at D, and the alkaline lye path is illustrated by dotted line arrows commencing at F, the alkaline lye being discharged at G. Fatty acid from a tank I is used to neutralize the alkaline soap from H for discharge as neutral soap at J. Specification 320,331, [Class 91], is referred to.
