Aqueous cleaning and disinfecting compositions which include quaternary ammonium compounds, block copolymer surfactants and further mitigating compounds which compositions feature reduced irritation

An aqueous hard surface disinfecting and cleaning composition in a concentrated form which exhibits reduced irritancy which consists essentially of:

• 0.001-5.0% wt. of a quaternary ammonium compound having germicidal properties;
• a mitigating effective amount of a binary surfactant system which includes both 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, and a further 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,
• water to form 100% wt. of said concentrate composition.
