1. A solid fabric softening composition comprising:
(a) from about 5 wt. % to about 10 wt. % of one or more nonionic ethoxylated surfactants selected from the group consisting of linear alcohol C14-15 ethoxylate, isotridecyl alcohol ethoxylates and mixtures thereof;(b) from about 40 wt. % to about 60 wt.% of one or more solidification agents comprising polyethylene glycol having a molecular weight of 4000 (PEG-4000) and urea to incorporate the surfactant(s) in a urea driven solidification; and(c) from about 45 wt. % to about 55 wt. % of one or more softening agents comprising a quaternary ammonium component methyl bis[ethyl (tallowate)] -2-hydroxyethyl ammonium methyl sulfate and a polydimethyl siloxane with amino alkyl group, wherein the composition is free of fragrance, wherein the quaternary ammonium component is about 40 wt. % to about 45 wt. % of the composition and the polydimethyl siloxane is about 5 wt. % to about 10 wt. % of the composition, wherein the ratio of quaternary ammonium component to polydimethyl siloxane is between about 7:1 to about 8:1; wherein the composition is a solid block that is dilutable with water for delivery into a washing machine and remains solid up to and at 122 degrees F.
