Abstract:
A liquid fabric softening composition comprising a cationic biodegradable fabric softener, a dispersible polyolefin and an alkoxylated amino-functional polymer, wherein said alkoxylated amino-functional polymer is a non-oxidised, non-quaternized alkoxylated polyalkylene imine and said biodegradable cationic fabric softener is selected from the group consisting of quaternary ammonium compounds and amine precursors having the formula (I) or (II), below: ##STR9## wherein Q is selected from --O--C(O)--, --C(O)--O--, --O--C(O)--O--, NR.sup.4 --C(O)--, --C(O)--NR.sup.4 ;R.sup.1 is (CH.sub.2).sub.n Q--T.sup.2 or T.sup.3 ;R.sup.2 is (CH.sub.2).sub.m --Q--T.sup.4 or T.sup.5 or R.sup.3 ;R.sup.3 is C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 hydroxyalkyl or H;R.sup.4 is H or C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 hydroxyalkyl;T.sup.1, T.sup.2, T.sup.3, T.sup.4, T.sup.5 are independently C.sub.11 -C.sub.22 alkyl or alkenyl;n and m are integers from about 1 to about 4; andX- is a softener-compatible anion; andwith the proviso that when said biodegradable cationic fabric softener is di(2-tallowylamido)ethyl methyl ammonium chloride), said amino-functional polymer is not an ethoxylated polyethyleneimine having a weight ratio of polyethyleneimine to ethylene oxide of 1.3:1 and a molecular weight of 60,000.
