The present invention relates to dryer-activated fabric softening compositions and articles, having improved antistatic and/or softening effects, for use in an automatic clothes dryer, especially those comprising, as essential ingredients: (A) fabric softener consisting essentially of (1) from about 5% to about 95% of preferably biodegradable quaternary ammonium compound selected from the group consisting of the compounds of Formula I: (R)4-m~ N+~[(CH2)n ~Y~R2]m X-; wherein each Y is ~OC(O)~ or ~C(O)~O~; m is 1 to 3; each n is an integer from 1 to 4; each R substituent is a short chain C1-C6 alkyl; a short chain C1- C4 hydroxyalkyl group, benzyl, or mixtures thereof; each R2 is a long chain, saturated or unsaturated with an Iodine Value (IV) of from about 3 to about 60, C8-C30 hydrocarbyl, or substituted hydrocarbyl substituent; and the counterion, X-, is any softener-compatible anion; Formula II: (R1)3-N+~(CH2)n~ C(YR2)H~ C(YR2)HZ X-; wherein, for any molecule: each Y is ~OC(O)~, or ~C(O)~O~; each R1 is C1-C4 alkyl or hydroxy alkyl; and R2, X-, and n are as previously defined in Formula I; Formula III: (R)4-m ~N+~[(CH2)n~ Y~R2]m X-, wherein R, R2, m, n, and X- are as previously defined in Formula I; and each Y is -NH-C(O)-; -C(O)-NH-; -C(O) -O-; or ~O~C(O)- wherein at least one Y group is -NH-C(O)- or -C(O)-NH-, and mixtures thereof; (2) from 0% to about 95% highly ethoxylated and/or propoxylated, preferably at least 5 ethylene oxide (EO) and/or propylene oxide (PO) groups per molecule, sugar derivative containing at least one long hydrophobic moiety per molecule, sugar derivative containing at least one long hydrophobic moiety per molecule, and (3) from 0% to about 95% of carboxylic acid salt of teriary amine; and (B) from about 1% to about 15%, unsaturated fatty acid having an IV of from about 3 to about 60. The amount of (A) present is at least sufficient to provide softening and/or antistatic effects. The active component(s) (A) can, and preferably do, contain unsaturation to provide improved antistatic benefits.
