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.

Liposome encapsulated active agent dry powder composition

The invention describes a protein extract in the form of an alcoholic extraction solution obtained from dried cereal gluten, which solution has been treated with glycerol and/or a short-chain alkanediol and evaporated under reduced pressure until the alcohol content is less than 5% by weight, preferably less than 1% by weight. This extract is outstandingly suitable for use in cosmetic preparations for care of damaged hair.

Protein extract from cereal gluten, preparation thereof and use thereof

Anhydrous cosmetic stick formulations such as lip balms, lipsticks, and underarm deodorant or antiperspirant sticks, comprising an organic matrix having particles homogeneously 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.

Process for producing solid anhydrous composition, and pharmaceutical

The process for preparing 1-functional allyl alcohol carboxylic esters comprises reacting a 3-functional allyl alcohol with the anhydride of the carboxylic acid at temperatures above 100.degree. C. in the presence of metal compounds of transition groups V to VII, namely at temperatures of 100-200.degree. C., preferably 130-150.degree. C. As metal compounds, it is possible to use oxidic metal compounds in the highest or at least second highest oxidation state of the transition metals, for example tungstic acid or its salts and/or tungsten(VI) oxide and/or molybdenum(V) oxide and/or molybdenum(VI) oxide and/or rhenium(VII) oxide. The 3-functional allyl alcohol and the carboxylic anhydride are advantageously used in equimolar amounts, if desired with a slight excess of anhydride, and an alkali metal salt of a weak acid, for example sodium carbonate or sodium acetate, can be added to the reaction mixture in an amount sufficient to trap free protons.
