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 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.

Heterocycles having odoriferous ketone or odoriferous aldehyde groups may be suitable in compositions comprising washing agents, cleaning agents, cosmetic agents, air care agents, insect repellents, or combinations thereof where the heterocycles release the ketones and aldehydes during hydrolysis. The heterocycle(s) may have the formula: ##STR00001##

A consumer product composed of ≤1% of a High-Performance fragrance composition and a consumer product active is provided. Use of reduced levels of the High-Performance fragrance composition provides for improved aesthetics such as improved clarity and viscosity, and reduced discoloration and caking.
