Abstract
Abstract The present invention pertains to a liquid detergent composition with improved cleaning performance. Specifically, it pertains to a liquid, clear, concentrated, homogeneous, aqueous detergent composition, designed in particular for hand washing table ware, i.e. dishes, glasses, cutlery and the like, containing a carefully balanced mixture of elected nonionic and anionic surface-active detergents, preferably in admixture with an organic acid material, yielding improved cleaning performances over the usual built and unbuilt liquid detergent compositions.
