Abstract (en)
A method for the preparation of light-coloured, low viscosity surfactant concentrates with solids contents of 40 - 60 wt.%, comprises mixing the following components : (A1) alk(en)yl oligo-glycosides; (A2) fatty acid N-alkylpoly-hydroxyalkyl amides, and (B) betain surfactants, in an (A)/(B) weight ratio of 90-10:10-90, with the provision that the concentrated starting materials are in gel form.
Abstract (de)
Es wird ein neues Verfahren zur Herstellung von niedrigviskosen, hellfarbigen Tensidkonzentraten vorgeschlagen, bei dem man (a1) Alkyl- und/oder Alkenyloligoglykoside und/oder, (a2) Fettsäure-N-alkylpolyhydroxyalkylamide und (b) Betaintenside im Gewichtsverhältnis a : b von 90 : 10 bis 10 : 90 vermischt, mit der Maßgabe, daß die Einsatzstoffe in der Gelphase vorliegen.
