1. 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.
