Abstract
Clear or translucent rinse-added fabric softening compositions are provided via the present invention which have reduced solvent or solvatrope levels. The composition according to the invention comprise: Preferred embodiments include low perfume level formulations. A preferred class of principal solvent extenders includes hydrophobic oils that aids in fluidizing the system which is characterized by a freezing point of less than 22° C. for in a mixture of the principle solvent extender and 2,2,4-trimethyl-1,3-pentanediol (20%/80% by wt). These principal solvent extenders include materials such as benzyl benzoate, methyl esters derived from canola oil, and mixtures thereof. Alternatively, the preferred principal solvent extenders include cumene sulfonates, xylene sulfonates, toluene sulfonates, C6-C14 sulfonates and sulfates, and mixtures thereof.
