Abstract
The invention relates to an alcohol-free cosmetic or pharmaceutical foam carrier comprising water, a hydrophobic solvent, a foam adjuvant agent, a surface-active agent and a water gelling agent. The cosmetic or pharmaceutical foam carrier does not contain aliphatic alcohols, making it non-irritating and non-drying. The alcohol-free foam carrier is suitable for inclusion of both water-soluble and oil soluble pharmaceutical and cosmetic agents.
Claims87
An alcohol-free foamable pharmaceutical or cosmetic carrier, comprising:
- (a) a foamable composition comprising:
- about 2-75% by weight of composition of a liquid, non-volatile hydrophobic solvent;
- about 80-98% by weight of composition of water;
- about 0.1% to 5% by weight of composition of a foam adjuvant agent selected from the group consisting of fatty alcohols, fatty acids, hydroxyl-substituted fatty alcohols, hydroxyl-substituted fatty acids, and fatty acids and fatty alcohols including at least one double bond in its carbon atom chain;
- about 0.1% to 5% by weight of composition of a surface-active agent;
- and
- about 0.1% to 5% by weight of composition of a water gelling agent and
- (b) a liquefied or compressed gas propellant in a container,
- which upon release provides a breakable foam suitable for topical or muscosal administration.

A method of treating, alleviating or preventing a dermatological disorder, comprising:
- administering topically to a subject having said dermatological disorder a therapeutically effective amount of a breakable foam composition comprising:
- (a) a foamable composition comprising:
- about 2-75% by weight of composition of a liquid, non-volatile hydrophobic solvent;
- about 80-98% by weight of composition of water;
- about 0.1% to 5% by weight of composition of a foam adjuvant agent selected from the group consisting of fatty alcohols, fatty acids, hydroxyl-substituted fatty alcohols, hydroxyl-substituted fatty acids, and fatty acids and fatty alcohols including at least one double bond in its carbon atom chain;
- about 0.1% to 5% by weight of composition of a surface-active agent;
- and
- about 0.1% to 5% by weight of composition of a water gelling agent.
- (b) at least one active agent, which is intended to prevent, alleviate or cure said disorder;
- and
- (c) a liquefied or compressed gas propellant.
