Abstract
Fabric softening actives having hydrophobic moieties containing, preferably, ester, or amide, linkages and mixed branched and unsaturated hydrophobic groups provide improved processing and stability as well as surprisingly good softening. Preferred compositions contain mono-ol and diol principal solvents having a ClogP of from about 0.15 to about 0.64, that have the ability to make clear aqueous fabric softener compositions containing relatively high concentrations of the said fabric softener actives having ester linkages in their long, hydrophobic chains. Other solvents may be present. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating. Other compositions can be prepared which are solid or dispersions of the said fabric softening actives.
