The present invention relates to an enzymatic process for the preparation of hydroxy fatty acid esters which are solid at room temperature and have improved melting behavior. Specifically, the enzymatic process includes reacting di- or polyols having at least two primary and optionally secondary or tertiary, hydroxyl groups, and hydroxy fatty acids and/or hydroxy fatty acid alkyl esters, and optionally, removing water of reaction or alcohol of reaction which forms.

The invention relates to essentially water-insoluble amphiphilic particles or molecules having predominantly hydrophilic and predominantly hydrophobic domains distributed anisotropically over their surface and a particle size ranging from 1 nm to 100 &mgr;m, consisting of antagonistic partial amounts of particles or molecules, which in each case have predominantly hydrophilic or predominantly hydrophobic domains, the partial amounts of the particles or molecules being agglomerated or associated over polar interactions or hydrogen bonds, as well as to a method for producing these particles or molecules and to the selective use of the particles or molecules.

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.
