Esterification reactions of alkanolamines are manipulated to favor the formation of incompletely esterified products, which can then optionally be neutralized or quaternized. The starting alkanolamines are synthesized or selected such that the alkanol groups on the alkanolamines are not all primary. These reaction mixtures have a higher concentration of either diesterified or monoesterified components than previously known reaction mixtures. The reaction mixtures can be advantageously used in fabric softener, paper softener, detergent, personal care and cleaner applications.

La présente invention concerne des manipulations de réactions d'estérification d'alkanolamines qui favorisent la formation de produits incomplètement estérifiés que l'on peut ensuite éventuellement neutraliser ou quaternariser. Les alkanolamines de départ sont synthétisées ou sélectionnées de sorte que leurs groupes alkanol ne sont pas tous primaires. Ces mélanges réactionnels présentent en composants soit di-estérifiés, soit mono-estérifiés, une concentration plus importante que les mélanges réactionnels connus jusqu'ici. Ces mélanges réactionnels peuvent être avantageusement utilisés comme agents adoucissants pour tissus ou papiers, comme détergents ainsi que comme produits de nettoyage et de soins personnels.
