The official Oleates are solutions of oleates in Oleic Acid. They are distinct from the solid oleates, which are made by double decomposition of salts of the metals and alkaline earths and sodium oleate, or Soap. (See Soap?) The liquid or official Oleates are intended for endermic medication. They are applied by inunction, when the Oleic Acid favors the absorption of the medicinal agent, the oleate in solution. When it is not desirable to administer remedies by the mouth, the Oleates afford an effective form of medication.

The solid Oleates are either dry powders, well adapted for pro-tectives as dusting powders, or soft, pliable masses to be applied in the form of ointments or plasters.
