Abstract

The present invention provides a defined alkylpolyglucoside having a degree of oligomerization of at least 1.7 to 3 and an alkyl radical comprising 8 carbon atoms, and mixtures of this alkylpolyglucoside with further alkylpolyglucosides, as cleaner concentrate. The present invention also relates to compositions which include the defined alkylpolyglucoside and a concentrated alkali metal hydroxide solution as well as a method of using the composition as a cleaner.
