Abstract

A stable composition for removing unwanted molecules from a surface comprises low-degree of substitution cyclodextrin derivatives. The compositions are suitable for capturing unwanted molecules from inanimate surfaces, including fabrics, including carpets, and household surfaces such as 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 cyclodextrin-compatible and -incompatible materials, and other optional ingredients.
