Abstract
The present invention relates to a soft-rinsing agent comprising a mixture of two soft-rinsing components, each of which is a quaternary salt as described herein. The mixture may contain 10-90% of the first component and 90-10% by the second component.
Claims38
An aqueous soft-rinsing agent comprising as an active ingredient an effective amount of a mixture of two soft-rinsing components containing a first component and a second component, wherein the
- (a) first component is a quaternary compound of the formula:
- ##STR36## wherein each R is independently hydrogen or alkyl containing 1-6 carbon atoms;
- each R.sup.1 is hydrogen or an alkylcarbonyl group containing 15-23 carbon atoms, provided that at least one of R.sub.1 is an alkylcarbonyl group;
- each R.sup.3 is an alkyl group containing 1-4 carbon atoms which is unsubstituted or substituted with 1, 2, or 3 hydroxy groups;
- each R.sup.2 is an alkyl group containing 1-4 carbon atoms which may be unsubstituted or substituted with 1, 2, or 3 hydroxy groups, or is a group of the formula ##STR37## R.sup.13 is an alkyl group containing 8-22 carbon atoms;
- R.sup.12 is an alkyl group containing 1-4 carbon atoms which is unsubstituted or substituted with 1, 2, or 3 hydroxy groups;
- R.sup.11 is hydrogen or alkyl containing 1-6 carbon atoms;
- R.sup.10 is hydrogen or alkylcarbonyl group containing 14-22 carbon atoms;
- A is an anion of a quaternizing agent;
- n is 0 or 1;
- x and y are independently 0 or 1 with (x+y)+(3-n)=4;
- m is 1 or 2;
- and
- g is 1, 2 or 3;
- and (b) the second component comprising at least one compound of the formula:
- ##STR38## wherein R.sup.4 is an alkyl radical having 8-22 carbon atoms;
- R.sup.5 is hydrogen or R.sup.6 ;
- R.sup.6 is CHX--CHY--O;
- X and Y are independently hydrogen or alkyl containing 1-6 carbon atoms with the proviso that X and Y cannot simultaneously be alkyl;
- R.sup.14 is hydrogen or alkylcarbonyl group containing 14-22 carbon atoms;
- R.sup.8 and R.sup.18 are independently an alkyl group containing 11-17 carbon atoms;
- Z and Z.sub.3 are independently water-soluble monobasic or polybasic anion;
- b is 1, 2, or 3;
- d is 0-6;
- a is b+1;
- and
- f and f.sub.3 are independently 1, 2, or 3.
