Abstract
An effective amount of active/cyclodextrin complex, in the form of particles having particle sizes below about 12 microns, is incorporated into solid consumer product compositions. The complexes provide fast release of the active when they are wetted even when the amount of water available to effect release of the active is limited as in personal use compositions like drugs, foods, and cosmetics where active release is typically effected by body fluids. Preferred actives include perfumes, flavors, and pharmaceutical materials that are used by consumers.
