FIELD: chemistry.

SUBSTANCE: invention relates to active fabric softener compositions. Described is an active fabric softener composition which contains a) not less than 50 wt % bis-(2-hydroxypropyl)-dimethylammonium methylsulphate ester of a fatty acid, having molar ratio of fatty acid moieties to amine moieties ranging from 1.5 to 1.99, average chain length of fatty acid moieties ranging from 16 to 18 carbon atoms, and iodine number of fatty acid moieties calculated for a free fatty acid ranging from 0.5 to 50, and b) 0.5-5 wt % fatty acid. Also described is a method of producing the fabric softener composition.

EFFECT: good softening capacity, good stability when stored in an aqueous dispersion, the softener composition can be used and processed in a liquid state without adding a flammable solvent.
