A solid fabric softening composition is disclosed which includes a quaternary ammonium fabric softening compound which is stabilized to form a solid with a mixture of a water soluble organic salt and a medium to long chain carboxylic acid. This stabilizing combination has been shown to effectively form a solid quaternary ammonium based fabric softening composition with up to as much as 70% by weight of quaternary ammonium compound. The formulations are stable at typical storage temperatures of up to 110&#xb0; F. and provide fabric softening similar to and even superior to other traditional liquid formulations.

Solid concentrated fabric softener composition

Disclosed are concentrated liquid rinse cycle fabric softener compositions comprising a quaternary ammonium cation and benzylated alcohol solvent having between 50% to 90% weight active ingredients. Benzyl alcohol is disclosed as a preferred solvent to produce a clear liquid solution formulation rather than emulsion. The concentrated liquid rinse cycle fabric softener compositions of the present invention possess desirable stability, sustainability and fabric-softening properties. Methods of use are further described.
