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.
Claims16
A composition for capturing unwanted molecules, said composition comprising low-degree of substitution cyclodextrin derivative.
A composition for capturing unwanted molecules, said composition comprising a cyclodextrin mixture comprising a cyclodextrin derivative having an average degree of substitution greater than that of low-degree of substitution cyclodextrin derivative, and either a low-degree of substitution cyclodextrin derivative or a non-derivatized cyclodextrin, wherein the cyclodextrin mixture effectively has an average degree of substitution equal to that of a low-degree of substitution cyclodextrin derivative.
A process of manufacturing a composition suitable for capturing unwanted molecules comprising the steps of:
- (a) providing low-degree of substitution cyclodextrin, a cyclodextrin-compatible surfactant, and a cyclodextrin-incompatible surfactant;
- (b) combining said cyclodextrin-compatible surfactant and said cyclodextrin-incompatible surfactant to form a first mixture;
- and
- (c) subsequently combining said low-degree of substitution cyclodextrin with said first mixture to form said composition suitable for capturing unwanted molecules.
