(57) [Summary]nA major solvent having a ClogP of about 0.15 to about 0.64, preferably about 0.25 to about 0.62, more preferably about 0.40 to about 0.60, especially mono-ol and diol major solvents; Is disclosed. These primary solvents include relatively high concentrations of fabric softener active ingredients (two long chain hydrophobic groups having a particular cis / trans ratio with highly unsaturated hydrocarbon moieties or branches and the same carbon content). A clear aqueous fabric softener composition comprising a long chain hydrocarbon group having an IV to the unsaturated group corresponding to a number and the same structure of the fatty acid having from about 70 to about 140). The primary solvent is used in an amount less than about 40%. The fabric softener active ingredient is prepared as disclosed herein, preferably in the presence of a chelating agent and / or antioxidant. Such substances are new. Other solvents may also be present. A premix of the fabric softener active ingredient, the primary solvent, and optionally other solvents, is useful in producing a complete formulation with / without the need for heating. |
