Abstract
Biodegradable fabric softener premix compositions are described containing (1) biodegradable softener actives that contain substantial unsaturation and (2) perfume. The premixes can be added at ambient temperatures to water containing acid, to provide a pH of from about 1.5 to about 5, to form finished compositions. The water can also contain calcium and/or magnesium salt to modify the viscosity.
