Quaternary ammonium surfactants derived from tertiary amines and fabric softeners containing quaternary ammonium surfactants

摘要

Cationic surfactant compound comprising, in the form of a quaternary ammonium salt, a product of condensation between, on the one hand a fraction of saturated or unsaturated fatty acids, or of derivatives of said acids chosen from the group comprising esters, anhydrides and acid chlorides, and on the other hand at least one tertiary amine, characterized in that, in combination:PP the alkyl chains of the tertiary amine together contain from 4 to 12 carbon atomsP Pthe alkyl chains of the tertiary amine together contain from 1 to 4 functions each chosen from the group comprising hydroxyl and amine functionsPPthe fatty acids fraction/tertiary amine mole ratio is between 1.85 and 1.40P Pthe fatty acids each possess a hydrocarbon chain in which the number of carbon atoms is between 5 and 23.
