    Abstract: Cosmetic or pharmaceutical formulations such as (a) anhydrous cosmetic stick formulations and (b) anhydrous aerosol spray formulations, comprising an organic dispersion medium having particles dispersed therein, which particles are preferably prepared by a process comprising spray-drying a mixture of liposome encapsulated active agent, modified starch, and optionally a hydrocolloid gum such as maltodextrin.

  • Patent number: 6106849
    Abstract: A "single-use" personal care product designed to replace conventional single use products such as small bars of soap, mini-bottles of shampoo, etc. A water soluble foamed polymer structure, such as produced by freeze drying acemannan derived from aloe vera, serves as the carrier for the personal care active ingredient, and provides the bulk to the structure. The dry foamed product has high void volume, good dimensional stability, high surface area, dissolves easily and completely upon exposure to water and hand mechanical action, and leaves no adverse residue on the skin. The product does not require bottling or complex wrapping, and is much more economical and environmentally friendly than the conventional single use products it replaces. The product can be conveniently carried in a purse or pocket, so that a consumer need never be without his/her favorite personal care products.

  • Patent number: 6083529
    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.
