1. A concentrated antimicrobial enzymatic floor cleaning composition comprising:

  • a) a tertiary amine antimicrobial;

    b) a lipase;

    c) an organic acid;

    d) a surfactant;

    e) a glycol ether solvent;

    f) an aminocarboxylate selected from the group consisting of methylglycinediacetic acid, glutamic-N,N-diacetic acid, and salts thereof; and

    g) about 50-80% water,wherein the total concentration of the surfactant, solvent and aminocarboxylate is from about 3.0 to about 50 wt. %, the ratio of the tertiary amine to the total concentration of the surfactant, solvent and aminocarboxylate is about (0.02-0.4);

    1, the composition has a pH range from about 4.9 to about 9.5, the composition has 15% of its original enzyme activity after 21 days at a temperature of 40°

    C., and the composition is free of boric acid or a boric acid salt.
