Abstract
Abstract Dryer-activated fabric softening compositions and articles having improved antistatic effects, for use in an automatic clothes dryer comprising: (A) at least about 5% of highly ethoxylated, preferably at least 5 ethylene oxide (EO) groups per molecule, sugar derivative containing at least one long hydrophobic moiety per molecule; and, preferably, (B) from about 10% to about 95%, of carboxylic acid salt of tertiary amine. The amount of (A) present is at least sufficient to provide improved antistatic effects and is not so much as to cause the composition to have unacceptable physical characteristics, e.g., stickiness. The active components (A) and (B) can contain unsaturation to provide improved antistatic benefits.
