Abstract
The invention provides a method for the preparation of an aqueous fabric softening composition comprising;(i) at least one cationic fabric softening compound having two or more alkyl or alkenyl chains each having an average chain length equal to, or greater than, C8 and(ii) at least one oily sugar derivative,wherein the cationic fabric softening compound (i), and/or the oily sugar derivative (ii) is/are separately mixed with another active component of the fabric softening composition to form a pre-mixture prior to the admixing of the softening compound (i) with the oily sugar derivative (ii).The invention also provides an aqueous based fabric softening composition produced by the method of the invention, and, a method of treating fabrics with the composition so produced.
