ABSTRACT:
A method is disclosed for controlling the viscosity of fabric softener compositions to thereby improve shelf life by first forming a microemulsion of a perfume and a surfactant by mixing a perfume and a surfactant at a temperature where each component is in the liquid state. Sufficient shearing forces are used to uniformly disperse the perfume in the surfactant to form a stable microemulsion of said perfume in said surfactant. The microemulsion is then mixed with a fabric softener base formulation.
