Abstract
The invention provides a fabric softening composition comprising;(i) one or more cationic fabric softening compound(s) having two or more alkyl or alkenyl chains each having an average chain length equal to, or greater than, C8, and(iv) at least one oily sugar derivative which 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 derivative has two or more ester or ether groups independently attached to a C8-C22 alkyl or alkenyl chain, and(v) a deposition aid comprising a mixture of one or more nonionic surfactant(s), and one or more one cationic polymer(s),and wherein the weight ratio of the nonionic surfactant to the cationic polymer is in the range 10:1 to 1:10.The invention also provides a method of treating fabric with the above compositions.
