| 主权项 | 1. A method of improving the stability of a composition comprising hydrogen peroxide or other peroxygen-containing compound or precursor thereof, the method comprising mixing into the composition an amount of a salt of ethylenediamine disuccinic acid comprising at least 1.6 mole of alkaline earth metal per mole of ethylenediamine disuccinic acid; wherein the resulting mixture has increased stability compared with a composition comprising an equivalent amount of a trisodium salt of ethylenediamine disuccinic acid and hydrogen peroxide or other peroxygen containing compound or precursor thereof. | ||
