Abstract
A tumble dryer article comprising: a mixture of at least two surfactants, (i) a first surfactant present in an amount of about 5 wt. % to about 70 wt. % and having an endotherm peak temperature of from about 75.degree. C. to about 155.degree. C., (ii) a second surfactant present in an amount of about 30 wt. % to about 95 wt. % and having an endotherm peak temperature of from about 35.degree. C. to about 70.degree. C., wherein the peak temperatures of the first and second surfactant of the mixture are different from each other by at least about 1.degree. C. as measured in a differential scanning calorimeter device and a melting transition temperature of the mixture being from about 50.degree. C. to about 120.degree. C.; and dispenser means for dispensing the mixture onto fabrics in a tumble dryer.
