Abstract
A substantially anhydrous composition suitable for topical application which contain 10-80% by weight of an anhydrous base which is liquid or semi-solid at room temperature; and 5-50% by weight of polyolefin microspherical particles having an average diameter of less than 25 microns, the amount of microspherical particles constituting at least 30% by weight of the anhydrous base.
Claims7
A liquid or semisolid anhydrous composition suitable for topical application, comprising an inactive carrier consisting essentially of:
- a) 10-80% by weight of an anhydrous pharmaceutically acceptable topically applicable carrier composition which is liquid or semi-solid at room temperature;
- and
- b) 5-50% by weight of polyolefin microspherical particles having an average diameter of less than 25 microns and having a density of greater than 0.915 g/ml, where the amount of microspherical particles constitutes at least 30% by weight of the said anhydrous pharmaceutically acceptable carrier.
