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.

Des agents actifs d'assouplissement de tissus présentant des fractions hydrophobes contenant, de préférence, des liaisons esters ou amides et des groupes hydrophobes ramifiés et insaturés mélangés procurent un meilleur traitement et une meilleure stabilité ainsi qu'un assouplissement étonnamment bon. Les compositions préférées contiennent des solvants principaux mono-ol et diol présentant une valeur ClogP (logP calculé) comprise entre environ 0,15 et environ 0,64, lesquels ont la capacité de rendre transparentes les compositions d'adoucisseur aqueux pour tissus contenant des concentrations relativement élevées desdits agents actifs d'adoucisseur pour tissus présentant des liaisons esters dans leurs chaînes hydrophobes longues. On peut prévoir d'autres solvants. Des pré-mélanges des agents actifs d'adoucissement de tissus, les solvants principaux, et facultativement, d'autres solvants sont utiles dans la préparation de formulations complètes sans chauffage ou à limitation du chauffage. On peut préparer d'autres compositions lesquelles sont solides ou des dispersions desdits agents actifs d'assouplissement de tissus.
