Abstract
The present invention concerns a thickened viscoelastic cleaning formulation comprising, in aqueous solution: (a) an active cleaning compound; and (b) a viscoelastic thickening system comprising a tetradecyldialkylamine oxide and a hydrophobic organic counterion; wherein the formulation has a viscosity of at least 500 cP at 20.degree. C. The present invention is characterized as a means for reducing the characteristic "bleach odor" found in hypochlorite cleaning compositions of the prior art, particularly those which are volatilized upon dispensing. The compositions of the present invention may further be formulated to have utility as a hard surface cleaner, or as a drain opener.
