Abstract: Stabilized peroxide-containing compositions stabilized with urea and urea/chelator stabilizer blends are provided. The compositions are particularly suitable for, but not limited to, cleaning applications on surfaces within food and beverage industries which may require the use of materials that are acceptable for incidental food/food products/feed contact. Further, the stabilized compositions are particularly suitable for applications requiring materials that are generally regarded as safe (GRAS) or for applications where non-GRAS materials must be minimized. Methods of stabilizing peroxide-containing compositions and methods of using the compositions are also provided.
