A stable, homogenous and viscous softener formulation is claimed which contains less than 50 % by weight of an esterquat compound of the formula wherein R 1 is -C 2 H 4 OH or -C 2 H 4 OCOR 2 , R 2 is C 11 -C 21 -alkyl or alkenyl and A is an anion, as methylsulfate, bromide, iodide and, preferably, chloride, said esterquat being prepared by esterification of methyldiethanolamine with fatty acids and subsequent quaternization, with preferably methylchloride, the fatty acids containing at least 50 % by weight of saturated C 18 -fatty acid, comprising a final product containing at least 50 mol % of diester quat and at least 10 mol % of monoesterquat and having an acid value of less than 0.12 meq/g of esterquat active material, the rest being water and an organic solvent.
