Process for the quaternisation of fatty acid esters of triethanolamine and imidazolinamides in alkoxylated fats or oils as the reaction medium and the use of the reaction mixture as a fabric conditioner component

摘要

The invention relates to a process for the quaternisation of triethanolamine fatty acid esters and imidazolinamides with customary quaternising agents in alkoxylated natural fats or oils or their mixtures with free fatty acids or mono- and/or diglycerides as the reaction medium, and to the use of the resulting reaction mixtures as laundry conditioner components. By replacing the hitherto customary N-alkyl-N,N,N-trihydroxyalkylammonium fatty acid ester salts or 1-alkyl-2-alkyl-3-amidoimidazolinium salts (termed quats for short) in 2-propanol as the solvent with the claimed quats in alkoxylated fats as the reaction medium, the quantity of quats can be reduced by up to 68% for the same softening effect.
