Abstract: A process for producing glucoprotamines by condensation of N-substituted propylene diamines with 2-aminoglutaric compounds in which the reaction is carried out in the presence of aminosilicones is disclosed. Glucoprotamines produced in accordance with the disclosed process exhibit improved color quality and longer storage stability.

Abstract: A process is disclosed for producing fluid imidazolinium tensides by reaction of 1-hydroxyethyl-2-alkylimidazolines with neutralized quaternary agents and hydrolysis of the quaternary products thus obtained with aqueous bases. The 1-hydroxyethyl -2-alkylimidazolines are added at a high temperature to an aqueous solution of the neutralized quaternary agents at a molar proportion between imidazoline derivates and the quaternary agents from 1:1.5 to 1:3. The reaction mixture thus obtained is maintained at a temperature in a range of 70.degree. to 85.degree. C. for 30 to 120 minutes, 0.85 to 1.0 mol alkali metal hydroxides, referred to the amount of quaternary agents added during step (a), are added thereto within the 30 to 120 minutes at a temperature in the range of 75.degree. to 85.degree. C., and the reaction mixture thus obtained is maintained at a temperature in the range of 75.degree. to 90.degree. C. for 140 to 220 minutes.
