Abstract
The present invention relates to a liquid fabric softening composition comprising a cationic biodegradable fabric softener and an alkoxylated amino-functional polymer, whereby said combination provides an increased color care benefit on treated fabrics but also enables the use of higher levels of polymers without being detrimental to the stability of the composition.
Claims23
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;
- and
- X- is a softener-compatible anion;
- and
- with 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.
