1. An aqueous hard surface disinfecting and cleaning composition in a concentrated form which exhibits reduced irritancy which comprises,0.001-5.0% wt. of a quaternary ammonium compound having germicidal properties;

  • 01-10% wt. of a nonionic surfactant compound which is based on a polymeric alkylene oxide block copolymer comprising ethylene oxide units and one or more alkylene oxide units selected from the group consisting of;

    propylene oxide units, butylene oxide units or both;

    a mitigating effective amount of a compound selected from;

    A) 0.01-10% wt. urea;

    C) 0.01-10% wt benzoates, including alkali or alkaline benzoate salts;

    D) 0.01-10% wt ethoxylated lanolin;

    0.1-10% wt. of a second nonionic surfactant;

    0-3% wt. of a polymeric cationic surfactant based on a polyquaternary ammonium salt;

    0-3% wt. of a builder;

    optionally, minor amounts of up to about 5% wt. of one or more conventional additives particularly coloring agents, fragrances and fragrance solubilizers, viscosity modifying agents such as thickeners, pH adjusting agents and pH buffers including organic and inorganic salts; and
