Abstract
A topical ointment pharmaceutical composition that uses a lipophilic base, a pharmaceutical active and, dispersed in the base, from about 1% to about 50% by weight of the total composition of hydrogenated non-melted castor oil in powder form. The result of using hydrogenated non-melted castor oil in powder form is a surprising pharmaceutical elegance perceived to be smoother in texture and more spreadable than an ointment made by melting the hydrogenated castor oil.
