688.    ---------------.  [DEN OTTER, H. P.]  [Soap From Synthetic Fat Acids.  IV.]  Chem. Weekblad, vol. 43, 1947, pp. 740-747; Chem. Abs., vol. 42, 1948, p. 1439.

      Sample of synthetic fat acids as used in Germany in 1943-1944 was found to have a composition approximately similar to that of a mixture of 50% coconut-oil-fat acids and 50% hard-fat acids but to contain little oleic acid.  On preparation of the Na soap-fat acid, losses of 5% were observed.  The soap contained 0.71% NaCl.  Compared with soaps made from natural-fat acids it lacked plasticity; it suffered greater loss in use; its foam was equal in quantity but less stable; its cleaning powder was inferior; and its odor was disagreeable.
