Beschreibung
Zusammenfassung:	An abrasive-free cleaning composition is provided 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 effective to provide cleaning activity and, in association with the colloidal thickener, thickening. The composition also includes an electrolyte/buffer effective to promote an environment in which the thickener and surfactant associate to provide thickening. The cleaning composition has desirable viscosity and rheological properties, and demonstrates significant viscosity 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 figure compares the viscosity stability of the provided cleaning compositions with a composition which does not contain ionic calcium. A method of preparing an abrasive-free cleaning composition and a method of cleaning a substrate with an abrasive-free cleaning composition are also provided.
