## Abstract

The present invention relates to an aqueous alkaline composition with good wetting ability, which composition is dilutable with water without exhibiting any phase separation. The composition contains a surface active nonionic alkylene oxide adduct of an alkyl-branched alcohol, with a good wetting ability, a hexyl glycoside and/or an octyliminodipropionate and a further surface active nonionic alkylene oxide adduct having an HLB-value according to Davies of at least 6.4. The Compositions may be used for the cleaning of hard surfaces, in scouring and mercerizing processes and for laundry.
