Description
1226~07 - 1 - C.3031 AQUEOUS FABRIC SOFTENING COMPOSITION
This invention relates to an aqueous fabric softening composition, in particular to a composition containing a water-insoluble cat ionic fabric softener.
British Patent Specification No GAB 1 104 441 (UNILEVER/TUNE) discloses aqueous fabric softening compositions which contain up to 10~ by weight of a water-insoluble cat ionic fabric softener together with a fatty acid ethanolamide which is included to enhance the softening effect and to provide an anti-static finish on fabrics treated therewith. Sodium carbonate may be added to these compositions to control product thickness.
As the cat ionic softener is water-insoluble, this can lead to high product viscosities, especially on storage.
We have now surprisingly discovered that products with lower viscosities, which are more stable on storage, can be obtained if the product contains specific electrolytes.
