Date Mar. 20, 1997Novel magnesiosilicate compounds for use in detergent compositions and as water softeners have a calcium binding capacity of at least 10 mg CaO per gram, a magnesium binding capacity of at least 10 mg MgO per gram and a calcium binding rate of no more than 300 seconds, all at room temperature. The compounds have a stuffed silica polymorph-related structure or a layered structure with a broad X-ray powder diffraction peak at a d-spacing of between 11 and 17 ANGSTROM . The compounds have an anhydrous composition MaMgbAlcSi1-(b+c)Od, where M-alkali, 0.0 |
