The invention provides fabric conditioning compositions, which include as the conditioning agent, one or more quaternary ester ammonium salt compounds, which include a mixture of quaternary mono-, di- and tri-ester ammonium salt components, wherein the amount of quaternary diester ammonium salts is greater than about 40% by weight, and the amount of quaternary triester ammonium salts is less than about 20% by weight based on the total amount of quaternary ester ammonium salts. The composition contains a high level of quaternary diester ammonium salt content, and low level of quaternary triester ammonium salt content.
