AN IMPROVEMENT IN THE PROCESS OF COMPRESSING POWDERED TABLETABLE MATERIALS IS GAINED BY MIXING WITH SAID MATERIALS PRIOR TO TABLETING, A LUBRICANT COMPRISING, IN COMBINATION, A SILOXANE POLYMER AND DRY-MIXABLE PARTICLES OF A LUBRICATING OIL COATED WITH AN OIL-INSOLUBLE FILMFORMING SUBSTANCE. THE LUBRICANT ACTS AS BOTH A PUNCH FACE LUBRICANT AND AS A DIEWALL LUBRICANT FOR SAID TABLETABLE MATERIALS. THE POWDERED TABLETABLE MATERIALS LUBRICATED WITH THE ABOVE LUBRICANT CAN BE THOSE INTENDED FOR GENERAL CLEANING OF SOLID SURFACES OR THOSE INTENDED FOR THERAPEUTIC EMPLOYMENTS. |
