<p>A water-insoluble porous cross-linked polymeric matrix contains an antiperspirant in its pores, the pores being interconnected to permit the antiperspirant to be leached therefrom with water, with zero order release without change in pore geometry. The pores may additionally contain one or more other materials such as deodorants, moisturisers, lubricants and perfumes. The matrix can be shaped for application to the skin. An antiperspirant dispenser can comprise a matrix of the invention with a water reservoir therefor.</p> |
