Patent ID: 8618081

Claim:
A therapeutic composition comprising: a first rheology modulator comprising a pharmaceutical or a cosmetic active agent at least part of which is suspended in the therapeutic composition; and a carrier comprising: a) a second rheology modulator selected from the group consisting of (i) a combination of at least one fatty alcohol and at least one wax; (ii) a combination of at least one fatty acid and at least one wax; and (iii) a combination of: at least one fatty alcohol, at least one fatty acid, and at least one wax; and b) at least one hydrophobic solvent; the carrier being otherwise free of or containing less than 0.1% by weight of surfactant; wherein the at least one wax comprises a hydrogenated castor oil; wherein the viscosity of the therapeutic composition is at least about 30% higher than the viscosity of a first partial composition comprising the carrier without the first rheology modulator; and is higher than the viscosity of the first rheology modulator and the at least one hydrophobic solvent without the second rheology modulator; and wherein the viscosity of the first partial composition is less than about 25,000 cPs at room temperature.
