Abstract: A benefit agent delivery system can deliver benefit agents on demand. The benefit agent delivery system comprises a first electrode layer, a microcell layer comprising a plurality of microcells, and a porous second electrode layer. Each of the plurality of microcells are filled with a liquid mixture comprising reverse micelles in a hydrophobic liquid that are formed from a polar liquid, a surfactant or stabilizing particles, and a benefit agent. Application of an electric field across a microcell layer causes an increase in the rate of release of the benefit agent of the microcell through the porous second electrode layer.

The benefit agent delivery system comprises a first electrode layer, a microcell layer comprising a plurality of microcells, and a porous second electrode layer. Each microcell of the plurality of microcells are filled with a liquid mixture comprising reverse micelles in a hydrophobic liquid that are formed from a polar liquid, an ionic surfactant, and a benefit agent. Application of an electric field on the microcell layer affects the rate of release of the benefit agent through the porous second electrode layer.
