    A.D. 1893 N° 15,446 Date of Application, 24th June, 1893 Complete Specification Left, 24th Mar., 1894—Accepted, 25th May, 1894 PROVISIONAL SPECIFICATION. Manufacture of Oleaginous or Saponaceous Compounds suitable for Producing* Medicinal Emulsions for Absorption by tbe Skin, or for Disinfection. I, Friedrich Wilhelm Klever, Manufacturing Chemist, of Brandenburger- strasse, Cologne, in the German Empire, do hereby declare the nature of this invention to he as follows :— My invention has for its object to impart to certain medicaments, such as creosote, 5 camphor, chloroform, ichthyol iodoform, oil of turpentine, menthol, pyoctanin, pyrogallol, chrysarobin, eucalyptus oil, and also to disinfectants, such as creolin, a permanent capacity for forming emulsions, or to increase such capacity, if already existing, and to facilitate the absorption of these medicaments and disinfectants by the skin. 10 For this purpose I combine the said medicaments or active ingredients with mineral oils, which have been saponified by any known method, until they are capable of forming emulsions with water and with aqueous solutions, said com¬ bination being preferably effected under pressure in a hermetically closed retort. By their combination with these mineral oil compounds the said medicaments 15 and disinfectants are rendered capable of forming emulsions with any desired quantities of water, milk and similar liquids, and especially also with the secretions of the skin or of wounds, or their capacity for forming such emulsions is improved, their absorption by the uninjured skin is facilitated, and as far as they are at all suitable for internal use, their application for this purpose in mixture with water, 20 milk or other beverages is facilitated. The relative quantities of the medicaments and disinfectants depend, on the medical requirements, in the case of creosoie it may range from less than 1 per cent, to about 35 per cent., in the case of iodoform from less than 1 to about 5 per cent.

Manufacture of Oleaginous or Saponaceous Compounds suitable for Producing* Medicinal Emulsions for Absorption by tbe Skm, or 30 for Disinfection. I, Friedrich Wilhelm Klever, Manufacturing Chemist, of Brandenburger- strasse 6, Cologne, in the German Empire, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement :— 35 The attempts hitherto made to take advantage, for manufacturing purposes, of the fact that mineral oils of every description will combine with oxygen and with bodies containing oxygen, such as the alkalies for example, have been confined to the employment of such mineral oils for the purpose of purification, in the manufacture of hard and soft soaps, such as are commonly met with in the market 40 and are known as “commercial” or “ industrial soaps.” . With this object in view’, the mineral oils have been mixed with oleic acids in proportions varying from 20 to 60 °/Q and upwards, the mixture being then subjected [Price 8J.]
