A high-viscosity, low-solids fabric softener formulation comprising (a) a low-solids fabric softener composition which includes from about 1 to about 10 % of at least one dialkyl quaternary ammonium compound dispersed in water; and (b) at least one amine ethoxylate having the formula(R(nEO))s NH t, wherein R is a saturated or unsaturated, linear or branched alkyl containing from to 22, preferably 12-18, carbon atoms; EO is ethoxylate; n is the number of moles of EO and is from 1 to 10, preferably 2-5; s=1, 2 or 3; t=0, 1 or 2, and s+t=3. The addition of the amine ethoxylate to the low- solids fabric softener composition enhances not only the viscosity of the fabric softener composition, but also the softening performance thereof. The enhanced viscosity is achieved without the use of any polymeric thickening agents. -28-
