Antimicrobial, hard surface cleaning compositions that effectively clean and reduce microorganisms on a surface without resulting in unacceptable filming and/or streaking residue on the surface, generally comprise (a) cationic antimicrobial active; (b) nitrogen-containing polymer; and (c) surfactant. Preferred antimicrobial, hard surface cleaning compositions for use in no-rinse cleaning methods comprise (a) from about 0.001% to about 0.5%, by weight of the composition, of surfactant; (b) cationic antimicrobial active; and (c) nitrogen-containing polymer. Methods of cleaning and reducing microorganisms on hard surfaces comprises contacting the surfaces with such compositions and preferably allowing the compositions to dry on the surface without rinsing the composition from the surface using water or other rinsing solution.

La présente invention concerne des compositions antimicrobiennes destinées au nettoyage des surfaces dures, qui permettent de nettoyer et de réduire efficacement le nombre de micro-organismes sur une surface, sans laisser sur celle-ci de résidus inacceptables tels que pellicules ou traînées. Les compositions de l'invention comprennent généralement : (a) des agents actifs cationiques antimicrobiens ; (b) un polymère contenant de l'azote ; et (c) un tensioactif. Les compositions antimicrobiennes de nettoyage de surfaces dures préférées, qui sont utilisées selon des procédés de nettoyage sans rinçage, comprennent : (a) un tensioactif dans une quantité comprise entre environ 0,001 % et environ 0,5 % en poids de la composition ; (b) des agents actifs cationiques antimicrobiens ; et (c) un polymère contenant de l'azote. Selon les procédés de l'invention qui permettent de nettoyer et de réduire le nombre de micro-organismes sur les surfaces dures, on met ces surfaces en contact avec les compositions précitées et, de préférence, on laisse ces compositions sécher sur la surface sans les rincer à l'eau ou à l'aide d'une autre solution de rinçage.
