First Claim
Patent Images
1. An aqueous hard surface disinfecting and cleaning composition in a concentrated form which exhibits reduced irritancy which comprises, a 0.001-5% wt. of a quaternary ammonium compound having germicidal properties;
- 0.001-10% wt. of a nonionic surfactant compound which is based on a polymeric alkylene oxide block copolymer;
0.01-10% wt. of at least one surfactant based on an alkoxylated fatty amine compound;
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 said compositions.

Abstract
Aqueous disinfecting and cleaning compositions and concentrates which are efficacious against gram positive and gram negative bacteria, have relatively low volatile organic content ("VOC") and are surprisingly mild to the user of the compositions. The compositions include a quaternary ammonium compound as its primary germicidal active agent, have a low content of active constituents, and do not include organic solvents such as alcohols, glycols, or glycol ethers in significant amounts.
