Abstract

Clear, or translucent fabric softener compositions comprise fabric softener compound, principal solvent system, and high electrolyte levels. The high electrolyte level allows for a broader range of principal solvents to be used and/or reduces the incidence of increased viscosity when low levels of principal solvent are used. Phase stabilizers which are primarily ethoxylated hydrophobic materials can be used to reduce the amount of principal solvent that is needed and/or to stabilize the compositions in the presence of the highest levels of electrolyte. Specific phase stabilizers provide additional benefits including improved softening. Specific electrolytes provide improved results. Addition of primary solvents and/or phase stabilizers to the softener compounds can improve the viscosity/handling of the compounds and the ability to create the finished compositions.
