Aqueous cleaning and disinfecting compositions having reduced irritation characteristics based on quaternary ammonium compounds including block copolymer surfactants and further surfactants

An aqueous disinfecting and cleaning composition in concentrated form which exhibits reduced irritancy which comprises:

• a disinfecting effective amount of a quaternary ammonium compound having germicidal properties.
• 0.01-10% wt. of a nonionic surfactant compound which is based on a polymeric alkylene oxide block copolymer;
• a mitigating effective amount of a compound selected from
• A) ethoxylated Cellulose wherein the relative weights of the polymeric alkylene oxide block copolymer to the ethoxylated cellulose is from 1:0.1 to 1:1;
• C) alkylamidopropylbetaine wherein the relative weights of the polymeric alkylene oxide block copolymer to the alkylamidopropylbetaine is from 2:1 to 1:2;
• 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 the aqueous disinfecting and cleaning composition in concentrated form.
