Zusammenfassung:A method for opening drains using a phase stable, viscoelastic drain opening composition includes introducing to a drain pipe restriction or clog a mixture having a cleaning active and a viscoelastic thickening system containing a quaternary ammonium compound, an organic counterion, and a free amine. The amount of free amine in the composition is limited, and is based on the amount of the quaternary ammonium compound present, in order to maintain phase stability and to achieve further enhanced rheological and aesthetic properties in the composition. The viscoelastic quality of the composition permits rapid penetration of the formulation through standing water with minimal dilution to deliver actives to the clog material, thus providing advartageous utility as a drain opener.
