I have received many requests for a working formula for the cream which I suggested a few years ago, as well as requests for its publication. The following formula gives a good and practically uniform product, if the compounding is done by a careful pharamacist who takes pride in his results. Melt the stearic acid. At the same time, dissolve the potassium carbonate in 320 cc. of water and heat to about 170 F. on the hot water bath. Bring the stearic acid to the same temperature and mix the two. Continue this temperature on a hot water bath, and stir occasionally until the reaction is complete. Dissolve the powdered borax in 100 cc. of water; add the quince jelly and heat on the hot water bath to about 170 F. Add this mixture to the first, which should be at the same temperature, and again leave on the hot water bath till the reaction is complete. Heat the glycerite of starch to the same temperature, stir in the powdered zinc oxide with a glass stirring rod and add to the other mixture, stirring occasionally. Let the mixture cool, add flavoring (oil Ylang Ylang recommended) and mill.
