1. An antimicrobial, hard surface cleaning composition comprising:

  • (a) from about 0.001% to about 15%, by weight of said composition, of a surfactant selected from the group consisting of nonionic surfactant, anionic surfactant, zwitterionic surfactant, amphoteric surfactant, and mixtures thereof, (b) a cationic antimicrobial active;

    (c) a nitrogen-containing polymer, wherein said nitrogen-containing polymer is selected from the group consisting of;

    (i) polyalkyleneimines;

    (ii) modified polyamines having the formulae;

    (aa) (PA)w(T)x;

    (bb) (PA)w(L)z;

    or (cc) [(PA)w(T)x]y[L]z; and

    (iii) mixtures thereof;



    wherein PA is a grafted or non-grafted modified or unmodified polyamine backbone unit, T is an amide forming polycarboxylate crosslinking unit, and L is a non-amide forming crosslinking unit, provided that for compounds of type (i) and (iii) the indices w and x have values such that the ratio of w to x is from 0.8;

    1 to 1.5;

    1;

    for compounds of type (ii) the indices w and z have values such that said modified polyamine compounds comprises from about 0.05 to about 2 parts by weight of said L unit;

    for compounds of type (iii) the indices y and z have values such that said modified polyamine compound comprises from about 0.05 to about 2 parts by weight of said L unit; and

    (d) aqueous carrier comprising water and optional organic solvent.
