We distinguish between soft soaps (fat saponi- fied by ])otash-lye) and hard soaps (fat saponified by soda- lye). When all of the alkali of the soap is combined witli fatty acids the soap is neutral. The action of the soaps is said to be due to the soluble basic, fatty-acid salt. Over-fatted soaps are those which contain along with the fatty-acid salts, of which neutral soap consists, a certain quantity of unsaponified fat. Unna's over- fatted or basis-soap is made of the best beef-tallow and a mixture of two parts of soda-lye and one part of potash- lye ; sufficient olive-oil is added to the soap-mass so that about 4 per cent, will remain unsaponified. Eichhofif has produced soaps containing various pulverulent substances. We employ, in addition, Hebra's spiritus saponatus kalinus (tinctura sapouis viridis) according to the follow- ing directions : Saponis viridis, 200 (3I gr. xv). Solve leni calore in Spirit, vini, 100 (f^xxv gr. viiss). Filtra et adde Olei lavandulaj, • Olei bergamottae, dd 3 (gtt. xlv). Mi see et filtra.
