Aqueous heavy duty liquid laundry detergent compositions useful for laundering fabrics and providing cleaning and softening benefits. Such detergent compositions contain at least 5%, by weight of the composition, of a surfactant component; from about 0.1% to about 10% of a quaternary ammonium fabric-softening agent having the formula wherein R<SUB>1 </SUB>and R<SUB>2 </SUB>are individually selected from the group consisting of C<SUB>1</SUB>-C<SUB>4 </SUB>alkyl, C<SUB>1</SUB>-C<SUB>4 </SUB>hydroxy alkyl, benzyl, and -(C<SUB>2</SUB>H<SUB>4</SUB>O)<SUB>x</SUB>H where x has a value from about 2 to about 5; X is an anion; and (1) R<SUB>3 </SUB>and R<SUB>4 </SUB>are each a C<SUB>8</SUB>-C<SUB>14 </SUB>alkyl or (2) R<SUB>3 </SUB>is a C<SUB>8</SUB>-C<SUB>22 </SUB>alkyl and R<SUB>4 </SUB>is selected from the group consisting of C<SUB>1</SUB>-C<SUB>10 </SUB>alkyl, C<SUB>1</SUB>-C<SUB>10 </SUB>hydroxy alkyl, benzyl, and -(C<SUB>2</SUB>H<SUB>4</SUB>O)<SUB>x</SUB>H where x has a value from about 2 to about 5; and such compositions contain less than 10 ppm of trimethylamine and dimethylamine impurities.
