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.
