Abstract
A pharmaceutical or cosmetic carrier or composition for topical application characterized by rheological properties which render the carrier or composition semi-solid at rest and a liquid upon application of shear forces thereto. The composition or carrier are prepared by mixing 1–25 percent of a solidifying agent and 75–99 percent of a hydrophobic solvent, by weight, wherein at least one of them has therapeutic or cosmetic benefits, in the presence or absence of a biologically active substance.

A pharmaceutical or cosmetic composition comprising:
- (a) an oleaginous pharmaceutical or cosmetic carrier comprising, by weight:
- 75–99 percent of a hydrophobic solvent, and
- 1–25 percent of a solidifying agent, wherein said solidifying agent consists essentially of a long chain fatty alcohol having at least 15 carbon atoms in its carbon backbone and a fatty acid having at least 18 carbons in its carbon backbone,
- wherein the carrier is semi-solid at rest and liquefies upon application of shear forces thereto;
- and
- (b) a therapeutically or cosmetically effective amount of a biologically active substance.
