1. A pharmaceutical or cosmetic composition comprising:
- a. water;
b. at least two poloxamers at a concentration of about 0.1% to about 5% by weight of the composition;
c. one or more active agents,wherein the composition is pressurized with a liquefied or compressed propellant;
wherein the weight ratio of the composition to the propellant is about 100;
5 to about 100;

Abstract
Pharmaceutical or cosmetic compositions and methods for their use are provided comprising water and a surfactant polymer system comprising a Poloxamer at a concentration of about 0.1% to about 15% by weight; wherein when the Poloxamer is between about 0.1% to about 5% Poloxamer. The composition can further comprise a supporting agent comprising a non-ionic surface active agent or a supporting agent comprising a non surfactant polymer or polysaccharide and an active agent, where the Poloxamer is capable of fixing the composition on delivery to a body surface. There are further provided therapeutic cell compositions and their uses.

21. A pharmaceutical or cosmetic foamable composition for application to a delivery site in a subject, the composition comprising:
-
A. a carrier comprising; a. about 5% to about 20% by weight of the carrier of at least two poloxamers; b. water; c. about 0.2% to about 15% by weight of the carrier of at least one hydrophobic solvent; d. about 0.5% to about 5% by weight of the carrier of at least one surfactant; e. about 0.5% to about 15% by weight of the carrier of at least one hydrophilic solvent; f. one or more active agents, which optionally may be encapsulated; and B. a propellant, wherein the composition is stored in an aerosol container and upon release expands to form a breakable short term stable foam; wherein the weight ratio of the carrier to the propellant is about 100;
5 to about 100;
25;wherein the at least two poloxamers are a synergistic combination of at least one liquid poloxamer and at least one solid poloxamer; and wherein the one or more active agents are soluble in the composition. - View Dependent Claims (22, 23, 24, 25, 26)
