An aqueous fabric softener comprising
- A) 22-30% by weight of one or more compounds of the general formula (1) ##STR9## in which R is --H or --CH.sub.3, R.sup.8 is H or --CH.sub.3 and at least one R.sup.8 group is an acyl radical having 6-22 carbon atoms, which optionally contains multiple bonds, wherein the acyl radical is unsubstituted or substituted with --OH;
- R.sup.9 is --CH.sub.3 or a radical of the formula --CH.sup.2 --CH(R)--OH;
- R.sup.10 is H, --CH.sub.3, --C.sub.2 H.sub.5, or --C.sub.2 H.sub.4 --OH;
- y is 1 or 2 and x is 2;
- and A.sup.- is an organic or inorganic anion;
- and
- B) 0-7% by weight of an amino amide of the general formula (2)
- (R.sup.11 --C(O)NH--(CH.sub.2).sub.3 --N(CH.sub.3).sub.2 R.sup.12).sup.+ A.sup.- ( 2)
- in which R.sup.11 is a hydrocarbon radical having 6-22 carbon atoms, which optionally contains multiple bonds, wherein the hydrocarbon radical is unsubstituted or substituted with --OH;
- R.sup.12 is one of the radicals --CH.sub.3, --C.sub.2 H.sub.5, or --C.sub.2 H.sub.4 --OH;
- and A.sup.- is an organic or inorganic anion;
- and
- C) 0.5-3% by weight of a compound of the formula (3) ##STR10## in which AO in each occurrence is the radical --CH(CH.sub.3)--CH.sub.2 --O-- or the radical --CH.sub.2 --CH.sub.2 --O--;
- R.sub.1, R.sup.2, R.sup.3 and R.sup.4 are identical or different from one another and each is a radical of the formula H--(O--CH(R)--CH.sub.2 --).sub.m --, in which R is H or a methyl or ethyl radical and each m is 1-10;
- R.sup.6 and R.sup.7 are identical or different from one another and each is H, --CH.sub.3, --C.sub.2 H.sub.5, or --C.sub.2 H.sub.4 OH;
- n is 1-30;
- and A.sup.- is an organic or inorganic anion;
- and
- D) 0-1.5% by weight of an electrolyte salt;
- and
- E) 0.5-1.5% by weight of a perfume oil;
- and
- F) 2.0-7.0% by weight of one or more compounds selected from the group consisting of short-chain alcohols containing 1 to 8 carbon atoms and compounds of the general formula (4)
- R.sup.13 O--(CH.sub.2).sub.c --O--(--(CH.sub.2).sub.d --O--).sub.e OR.sup.14 ( 4)
- in which R.sup.13 and R.sup.14 independently of one another are H, CH.sub.3 -- or C.sub.2 H.sub.5 --;
- c and d are each 2-6;
- and e is 1-10;
- and
- G) water to add up to 100% by weight.
