A non-staining fabric softening article especially adapted for use in an automatic clothes dryer, comprising:
- (a) a fabric conditioning amount of a softener mixture comprising:
- (i) a fabric softener component selected from the group consisting of sorbitan esters characterized by at least one free hydroxyl group and a melting point of at least about 38.degree. C., and mixtures thereof, said softener component being substantially free of unneutralized fatty acids;
- and
- (ii) a phase-modifying component selected from the group consisting of water soluble C.sub.10 -C.sub.20 neutralized alkyl sulfates, and mixtures thereof, the weight ratio of said softener component to said phase-modifying component being in the range of from about 100:1 to about 1:1;
- said softener mixture being characterized by a melting point in range of from about 38.degree. C. to about 100.degree. C., said mixture being in releasable combination with;
- (b) means for dispensing the softener mixture when said softening article is tumbled with damp fabrics in the dryer under heat sufficient to melt the mixture.
