Abstract

A stable dry powder skin care powder having prolonged and controlled release properties, useful as baby powders, body talcs, deodorizing powders, OTC eczema preparations, foot powders, anti-fungal powders, etc. The dry powder is preferably prepared by a process comprising spray-drying a mixture of liposome encapsulated active agent, starch and maltodextrin. The particle is designed so that activity of, e.g., an anti-inflammatory agent such as Dragosantol.RTM. can be specifically triggered by skin conditions, such as moisture, for optimal timing of delivery.
