Abstract:
A method for the preparation of an aqueous fabric softening composition comprising:(i) 0.5% wt to 30% wt of 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) 0.5 % wt to 50 % wt of at least one oily sugar derivative; wherein the oily sugar derivative is a liquid or soft solid derivative of a cyclic polyol or of a reduced saccharide, said derivative resulting from 35 to 100% of the hydroxyl groups in said polyol or in said saccharide being esterified or etherified, and wherein the oily sugar derivative has two or more ester or ether groups independently attached to a C8-C22 alkyl or alkenyl chain; wherein the cationic fabric softening compound (i) is separately mixed with a nonionic surfactant to form a pre-mixture prior to the admixing of the cationic softening compound (i) with the oily sugar derivative, or wherein the oily sugar derivative (ii) is separately mixed with a perfume to form a pre-mixture prior to the admixing of the softening compound (i) with the oily sugar derivative (ii).
