Abstract

A stable composition for removing unwanted molecules from a surface comprises functionally-available cyclodextrin, cyclodextrin-compatible surfactant, and cyclodextrin-incompatible surfactant. The compositions are suitable for capturing unwanted molecules from inanimate surfaces, including fabrics, including carpets, and hard surfaces including countertops, dishes, floors, garbage cans, ceilings, walls, carpet padding, air filters, and the like, and from animate surfaces, including skin, hair, and the like. The compositions can further comprise other cyclodextrin-compatible and -incompatible materials and other optional ingredients.
