Verfahren zur Verfluessigung waessriger Textilweichmacher

摘要

Aqueous textile softeners containing as active ingredient a condensate of 1 mole of a bis- or tris-hydroxyalkylamine of the formula where R1 is H, alkyl of 1 to 4 carbon atoms, hydroxyethyl or 2-hydroxypropyl and R2 is H or CH3, with from 0.8 to 2 moles of a fatty acid of 16 to 18 carbon atoms, the said condensate being in the form of a salt with an inorganic or organic acid or being partially or completely quaternized at the amine nitrogen, cannot readily be formed into liquids containing 10% or more of active ingredient. According to the invention liquids containing from 15 to 40% by weight of such an active ingredient can be formed by adding from 3 to 15% by weight based on the active ingredient of a compound of the formula II where n is an integer from 1 to 4, R3 and R4 independently of one another are methyl, ethyl or propyl, R5 is hydrogen or methyl and R6 is alkyl of 7 to 13 carbon atoms including a chain of at least 7 carbon atoms, as a salt of an inorganic or organic watersoluble acid, and bringing the pH of the formulation to 2.5 to 6. The softeners of the invention are used after dilution for softening textiles.
