Fixedly - quaternary ammonium surfactants, process for their preparation, bases and their dissipative plasticizers

摘要

Cationic surface-active compound comprising, in the quaternary ammonium salt form, a condensation product between, on the one hand, a fraction containing saturated or unsaturated fatty acids, or containing derivatives of the said acids, chosen from the group comprising esters, anhydrides and acid chlorides and, on the other hand, at least one tertiary amine, characterised in that, in combination: - the alkyl chains of the tertiary amine together comprise from 4 to 12 carbon atoms - the alkyl chains of the tertiary amine together comprise from 1 to 4 functional groups each chosen from the group comprising the hydroxyl and amine functional groups - the fatty acids fraction/tertiary amine molar ratio is between 1.85 and 1.40 - the fatty acids each have a hydrocarbon chain in which the number of carbon atoms is between 5 and 23. m
