    摘要: Light-colored alkyl oligoglycoside pastes can be obtained by a process in whicha) glycose is reacted with fatty alcohols in the presence of acidic catalysts at elevated temperature to a residual content of glycose of less than 0.1% by weight, based on the starting quantity of glycose,b) water of reaction released is continuously removed from the equilibrium,c) the reaction products are neutralized with a base, the molar ratio of hydrogen ions in the reaction mixture to added base being from 1:1 to 1:1.5,d) unreacted fatty alcohols is separated by distillation,e) the residue is subsequently processed by addition of water to a paste having a solids content of 30 to 70% by weight, based on the paste, the paste is alkalized and, optionally, bleached by methods known per se.

    摘要: The application pertains to the use of isosorbide ethers according to general formula (I) wherein R′ and R″ independently from each other represent a hydrogen atom or a alkyl- or unsaturated alkenyl moiety for the preparation of detergents and cleaners. Preferably R′ and/or R″ are linear or branched, saturated or unsaturated alkyl or alkenyl moiety containing 1 to 33 C-Atoms. A second, independent embodiment pertains to the use of these compounds as thickener for aqueous/surfactant compositions.
