Title:Body cavity foams
Abstract: The invention relates to an alcohol-free cosmetic or therapeutic foam carrier comprising water, a hydrophobic organic carrier, a foam adjuvant agent, a surface-active agent and a gelling agent. The cosmetic or therapeutic 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 therapeutic and cosmetic agents.
