Abstract
A light duty microemulsion liquid detergent composition, useful for removing greasy soils from surfaces with both neat and diluted forms of the detergent composition, includes a moderately water soluble complex of anionic and cationic surfactants, in which complex the anionic and cationic moieties are in essentially equivalent or equimolar proportions, an anionic detergent, a co-surfactant, an organic solvent and water. Preferably, the complex component is one in which the anionic and cationic moieties include hydrophilic portions or substituents, in addition to the complex forming portions thereof, the anionic detergent is a mixture of higher paraffin sulfonate and higher alkyl polyoxyethylene sulfate, the co-surfactant is a polypropylene glycol ether, a poly-lower alkylene glycol lower alkyl ether or a poly-lower alkylene glycol lower alkanoyl ester, and the organic solvent is a non-polar oil, such as an isoparaffin, or an oil having polar properties, such as a lower fatty acid ester or a lower fatty alcohol ester. Also within the invention are the described complex, preferably one of equimolar proportions of sodium C.sub.12-14 alkyl diethoxy ether sulfate and C.sub.12-14 alkyl-b…
