Biodegradable fabric softener premix compositions are described containing (1) biodegradable softener actives; optional low molecular weight solvent; (2) high boiling, water soluble solvent to lower the viscosity, while avoiding flammability; and (3) optional perfume. The premixes can be added at ambient temperatures to water containing acid, to provide a pH of from about 1.5 to about 5, to form finished compositions. The water can also contain calcium and/or magnesium salt to modify the viscosity. Compositions containing highly unsaturated softener actives have improved freeze/thaw properties.
Cette invention se rapporte à des compositions de prémélanges d'adoucissants textiles biodégradables, qui contiennent: (1) des agents adoucissants biodégradables; un solvant optionnel à poids moléculaire faible; (2) un solvant hydrosoluble à point d'ébullition élevé, destiné à abaisser la viscosité tout en évitant l'inflammabilité; et (3) un parfum optionnel. Ces prémélanges peuvent être ajoutés à température ambiante à de l'eau contenant de l'acide, pour former un pH compris entre environ 1,5 et environ 5, afin de produire les compositions finies. L'eau peut également contenir un sel de calcium et/ou de magnésium destiné à modifier la viscosité. Des compositions contenant des agents adoucissants hautement insaturés possèdent des propriétés de congélation/décongélation améliorées.
