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: a) a fabric softening active; b) a principal solvent; c) a principal solvent extender; and d) the balance carriers and adjunct ingredients. Preferred enbodiments 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.

Ces compositions d'adoucissant pour tissu, concentrées, stables et translucides ou incolores présentent des concentrations réduites en solvant ou en solvatropes. Cette composition renferme, (a), un agent adoucissant actif, (b), un solvant principal, (c), une matière de charge de solvant principal et, (d), des véhicules d'équilibre ainsi que des ingrédients d'appoint. Les compositions décrites dans les réalisations préférées ont de faible concentrations en parfum. Une classe préférée de matière de charge de solvant principal comporte des huiles hydrophobes favorisant la fluidification du système et se caractérisant par un point de congélation inférieur à 22 ·C pour un mélange constitué par ladite matière de charge et de 2,2,4-triméthyl-1,3-pentanédiol (de 20 à 80 % en pourcentage pondéral). Ces matières de charge comprennent des substances telles que du benzoate de benzyle, des esters méthyliques dérivés d'huile de colza canola et leurs mélanges. Dans une variante, ces matières de charge préférées comprennent des sulfonates de cumène, de xylène et de toluène, des sulfonates ainsi que des sulfates portant de 6 à 14 atomes de carbone et leurs mélanges.
