Concentrated mildly acidic hard surface cleaning compositions having a superior combination of cleaning and disinfecting comprise, by weight of concentrated composition: from about 0.5 to about 40% amine oxide detergent; from about 0 to about 4% nitrogen-containing chelant; and 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 cm2 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 cm2 or less; at least 10% of the amine oxide detergent within the diluted cleaning composition is protonated.
Compositions concentrées légèrement acides pour le nettoyage de surfaces dures, possédant des qualités supérieures de nettoyage et de désinfection. Elles renferment en poids : de 0,5 à 40 % environ d'un détergent à base d'oxyde d'amine; de 0 à 4 % environ d'un chélateur azoté; enfin, de 1 à 30 % environ d'un désinfectant quaternaire. Lorsque la composition concentrée est dilué pour former une composition avec une concentration d'oxyde d'amine de 0,5 %, au moins 10 % de l'oxyde d'amine détergent à l'intérieur de la composition diluée est protoné. La composition diluée a une tension de surface d'environ 27 dynes par cm2 ou moins et un pH de 3 à 7 environ. Les compositions de nettoyage diluées, préparées à partir des compositions concentrées, renferment de 40 à 12500 ppm environ d'un oxyde d'amine détergent, et de 50 à 1500 ppm environ d'un désinfectant quaternaire (quat), avec une tension de surface de 27 dynes par cm2 ou moins; au moins 10 % de l'oxyde d'amine détergent dans la composition de nettoyage diluée est protoné.
