    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.

    摘要翻译： 本发明提供了一种无磨料清洁组合物，其在水溶液中包含漂白剂，胶体增稠剂和二价离子钙源。 所述组合物还包含至少一种有效提供清洁活性的表面活性剂，并且与胶体增稠剂相关联，增稠。 该组合物还包括有效促进增稠剂和表面活性剂缔合以提供适当增稠的环境的电解质/缓冲剂。 具有其离子钙源的本发明清洁组合物具有所需的粘度和流变性能，并且显示出显着的粘度稳定性，流变稳定性，相稳定性和漂白稳定性。 清洁组合物在典型的储存条件以及延长的时间和升高的温度下保持这些期望的性能。 本发明还提供了一种制备无磨料清洁组合物的方法和用无磨料清洁组合物清洗基材的方法。 本发明还提供了具有上述优点的组合物，其特别可用于陶瓷基材如马桶碗的清洁，并且对于该应用具有额外的优点。
