This is a batch
process which involves the separation of glycerine.
After the complete
saponification of oils, by addition of brine (solution of sodium
chloride in water), the content of the pan is left to settle
in an upper layer of soap at about 60% TFM content and a lower
layer of water containing glycerine and the water soluble impurities
originally in the oils.
After the glyceric
waters have separated the soap is further washed diluting it
again with water to release the impurities still contained. One
further addition of brine separates the neat soap at ca. 62%
TFM from the water solution containing the remaining impurities.
The soap so
produced is perfectly "clean" even if the raw material
are not.
