<p>Shaped articles, such as cakes, sticks and other compacts, formulated with liquefiable powders containing various agents are disclosed for the delivery of cosmetic and other personal care products. In particular, microporous cellulosic powders, such a cellulose triacetate (CTA), are disclosed as high liquid content vehicles for the active agents. The liquefiable powders can be compacted to form firm cakes or formulated with binders to yield sticks. The resulting shaped articles are neither oily nor gritty and yet permit the application of the cosmetic or personal care agents by simply rubbing or brushing the formulation onto the skin, in such a manner that the powder liquefies and appears to vanish. Shaped articles made in accordance with the present invention permit the delivery of high concentrations of active agents without the problems normally associated with liquids and oils.</p> |
