Abstract
  • A study has been made of ointment bases prepared from mineral oil thickened with Bentone 38 gellant. The experimental work was divided into two distinct parts: (1) the development of ointment bases using the Bentone gellants, and (2) subsequent comparison of these bases with White Petrolatum, Plastibase Hydrophilic, and other bases in common use. Three different hydrophilic, water-absorbing ointment bases were prepared from Bentone 3B gellant and mineral oiI. Two of the bases were W/O emulsion bases. The third was an anhydrous or "grease type" base. In evaluating these bases, experimental data are presented for: (I) physical and chemical stability, (2) body and consistency, (3) drug release properties, and (4) handling and manufacturing characteristics.
