Abstract

A blooming type, hard surface cleaning concentrate composition includes as a blooming system the following essential constituents: a cationic quaternary ammonium surfactant; an anionic carboxylated alcohol alkoxylate surfactant; a surfactant compatibilizing agent; and, water. Further optional constituents may also be included including additional anionic, cationic, nonionic, amphoteric and zwitterionic surfactants especially to provide a further detersive effect; organic solvents such as alcohols, ethers, glycol ethers to aid in stain solubilization, as well as conventional additves such as coloring agents including dyes, fragrances, and others. In preferred embodiment, the concentrate compositions and cleaning compositions also provide a germicidal effect to hard surfaces. The cleaning concentrates exhibit a charateristic bloom when admixed to a larger volume of water, yet are substantially clear and shelf stable as concentrate compositions.
