               Soaps from the synthetic fatty acids, even when they form only 10-20% of the fat charge, have an unpleasant odor, which is imparted to the human skin when washed with the soap.  The extent varies with different individuals.  The odor is not found on cloth washed with the soap.  Refractionation of the fatty acids and removal of the lowest molecular-weight acids give some improvement.  The odor may be due in part to decomposition that takes place during heating of the anhydrous soap to 360° C., which is common to all German processes.  Development of the process in England depends on finding enough raw materials.
