Abstract
Concentrated mildly acidic hard surface cleaning compositions having a superior combination of cleaning and disinfecting comprise, by weight of concentrated composition: PA1 from about 0.5 to about 40% amine oxide detergent; PA1 from about 0 to about 4% nitrogen-containing chelant; and PA1 from about 1 to about 30% quaternary disinfectant. When the concentrated composition is diluted to form a diluted composition having a concentration of amine oxide of 0.5%, at least 10% of the amine oxide detergent within the diluted composition is protonated; the diluted composition has a surface tension of about 27 dynes per cm.sup.2 or less and a pH of from about 3 to about 7. Diluted cleaning compositions prepared from the concentrated compositions comprise from about 40 ppm to about 12,500 ppm of an amine oxide detergent, and from about 50 ppm to about 1500 ppm of a quaternary disinfectant (quat), and have a surface tension of about 27 dynes per cm.sup.2 or less; at least 10% of the amine oxide detergent within the diluted cleaning composition is protonated.
