    摘要: The present invention provides an abrasive-free cleaning composition which includes, in aqueous solution, a bleach, a colloidal thickener, and a source of divalent ionic calcium. The composition further includes at least one surfactant which is effective to provide cleaning activity and, in association with the colloidal thickener, thickening. The composition also includes an electrolyte/buffer which is effective to promote an environment in which the thickener and the surfactant associate to provide proper thickening. The inventive cleaning composition, with its ionic calcium source, has desirable viscosity and rheological properties, and demonstrates significant viscosity stability, rheological stability, phase stability and bleach stability. The cleaning composition maintains these desirable properties under typical storage conditions as well as over extended times and at elevated temperatures. The present invention also provides a method of preparing an abrasive-free cleaning composition and a method of cleaning a substrate with an abrasive-free cleaning composition. The present invention further provides a composition having the above-mentioned advantages, which is particularly useful in the cleaning of ceramic substrates, such as toilet bowls, and has additional advantages for this application.
