Toilet Soap Noodles

this is a batch process which involves complete saponification of oil with caustic and then separation of glycerine. First the complete saponification of oils takes place, by addition of caustic lye, then the mass is left to settle in the pan. Two layers are thus formed. The upper layer of soap at about 60% tfm content and a lower layer of water containing glycerine and the water soluble impurities originally found in the oils. The glycerine water which has been separated from the soap is further washed diluting it again with water.
