## Abstract

The present invention relates to a car dry-bright composition comprising from 1 to 30% by weight of quaternary ammonium compounds of the formula ##STR1## in which R.sup.1 is independently at each occurrence C.sub.6 -C.sub.22 -alkyl or C.sub.6 -C.sub.22 -alkenyl, m and n independently of one another are a number from 1 to 6, R.sup.2 is C.sub.1 -C.sub.4 -alkyl, R.sup.4 is hydrogen or C.sub.1 -C.sub.4 -alkyl, R.sup.5 is hydrogen or a group of the formula C(O)R.sup.1, R.sup.3 is C.sub.1 -C.sub.4 -alkyl or a group of the formula ##STR2## in which R.sup.4 and R.sup.5 are as defined above and p is a number from 1 to 6, and A.sup..crclbar. is an anion, and water and, if desired, further auxiliaries corresponding to the balance to 100% by weight.

## Claims

### Claim 1

An aqueous car dry-bright composition comprising:
a concentrate consisting essentially of:
(a) from 1 to 30% by weight of quaternary ammonium compounds of the formula ##STR8## in which R.sup.1 is independently at each occurrence C.sub.6 -C.sub.22 -alkyl or C.sub.6 -C.sub.22 -alkenyl,
m and n independently of one another are a number from 1 to 6,
R.sup.2 is C.sub.1 -C.sub.4 -alkyl,
R.sup.4 is hydrogen or C.sub.1 -C.sub.4 -alkyl,
R.sup.5 is hydrogen or a group of the formula C(O)R.sup.1,
R.sup.3 is C.sub.1 -C.sub.4 alkyl or a group of the formula ##STR9## in which R.sup.4 and R.sup.5 are as defined above and p is a number from 1 to 6,
and
A.crclbar. is an anion,
(b) from 2 to 10% by weight of a C.sub.8 -C.sub.22 -alkylamino-(C.sub.1 -C.sub.4)-alkoxylate, a C.sub.8 -C.sub.22 -alkylalkylene diamine, or a mixture thereof, and
(c) the butyl ether of ethylene glycol or propylene glycol;
said composition further comprising from 150 to 500 times the quantity of water, based on the weight of said concentrate.
