Abstract
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° F. and provide fabric softening similar to and even superior to other traditional liquid formulations.
