A white soft soap could be made from cocoanut oil and lard, but it would be very expensive. The palest soft soaps are made from refilled cottonseed arid linseed oils. The pan for making the soap should be provided with open and closed steam coils for heating. Suppose that LOO lb. of oil be taken as a standard; this will require 22 1b. of caustic potash (82 per cent.) for saponification. This should be dissolved in water to form two lyes, one of specific gravity 1.08 (16° Tw.), the other of specific gravity 1T5 (30 Tw.). Commence with half the oil, heat up with open coil, add the weak lye, stir continually till saponified, then add the remainder of the oil and the stronger lye and continue boiling till a portion taken out is quite clear. Then turn off the open steam, and concentrate by closed steam till it sets to a jelly when placed on glass. The pan should be twice the size of the charge to prevent frothing over.
