If the fabric softener hydrate is too concentrated, the desired viscosity profile of the final fabric softener product may not be achieved (e.g., need for thickeners to achieve the desired viscosity or a lack of pumpability (i.e., too thick) for the composition to be processed further). The method of any preceding claim, wherein the chilled water comprises a temperature at or below 10 C. 10. The fineness of the fibre or of the filament directly affects the softness of the yarn (woollens, worsteds, microfibers etc.). It is also worth underlining that no standard methods have been developed and established to determine exactly what the softness of a fabric is. This evaluation is therefore almost personal and carried out on the basis of operator.s experience. The recommended dose of Single Rinse fabric softener is added to the rinse solution and the laundry should soak for a few minutes. There is a continuing need to make fabric softener compositions that: (a) minimize components (thereby keeping raw materials costs down and reduce complexity); (b) provide consumer preferred rheology - particularly with low fabric softener active amounts (e.g., typically lower than about 7% fabric softener active); and maximize unilamellar vesicle structure of the fabric softener active as to enhance fabric softening efficiency while mitigating negative effectives of anionic carryover (i.e., from the wash liquor).
