## Abstract

An improvement for boosting the cleaning capacity of one or more enzymes includes providing one or more secondary paraffin-sulfonates to a cleaning composition. The method is particularly effective for textiles at low washing temperatures.

## Claims

### Claim 1

In a method of cleaning utilizing one or more enzymes, the improvement comprising providing one or more secondary paraffin-sulfonates having 8 to 22 carbon atoms for increasing the cleaning capacity of the one or more enzymes.

### Claim 2 (depends on 1)

The improvement as claimed in claim 1, wherein at least 95% by weight of the one or more secondary paraffin-sulfonates contain 14 to 17 carbon atoms.

### Claim 3 (depends on 1)

The improvement as claimed in claim 1, wherein 95 to 100% by weight of the one or more secondary paraffin-sulfonates contain a linear paraffin moiety and 0 to 5% by weight of the one or more secondary paraffin-sulfonates a branched paraffin moiety.

### Claim 4 (depends on 1)

The improvement as claimed in claim 1, wherein the counterions of the one or more secondary paraffin-sulfonates are selected from the group consisting of Na+, K+, Mg2+ and Ca2+.

### Claim 5 (depends on 4)

The improvement as claimed in claim 4, wherein the counterion of the one or more secondary paraffin-sulfonates is Na+.

### Claim 6 (depends on 1)

The improvement as claimed in claim 1, wherein 100% by weight of the one or more secondary paraffin-sulfonates contain a saturated paraffin moiety.

### Claim 7 (depends on 1)

The improvement as claimed in claim 1, wherein the sulfonate groups are distributed randomly over the nonterminal paraffin moiety of the one or more secondary paraffin-sulfonates, and from 75 to 95% by weight of the one or more secondary paraffin-sulfonates bear one sulfonate group and from 5 to 25% by weight of the one or more secondary paraffin-sulfonates two or more sulfonate groups.

### Claim 8 (depends on 1)

The improvement as claimed in claim 1, wherein the one or more enzymes are selected from the group consisting of protease, amylase, mannase, lipase and endolase.

### Claim 9 (depends on 1)

The improvement as claimed in claim 1, wherein the one or more secondary paraffin-sulfonates and the one or more enzymes are used in liquid washing compositions for textiles.

### Claim 10 (depends on 9)

The improvement as claimed in claim 9, wherein the cleaning capacity of the one or more enzymes is increased with respect to milk, starch, blood, chocolate and/or cocoa.

### Claim 11 (depends on 9)

The improvement as claimed in claim 9, wherein the cleaning capacity of the one or more enzymes with respect to stains on textiles is enhanced at wash temperatures of 5 to 60° C.

### Claim 12 (depends on 9)

The improvement as claimed in claim 9, wherein the amount of the one or more secondary paraffin-sulfonates is from 5 to 30% by weight.

### Claim 13 (depends on 9)

The improvement as claimed in claim 9, wherein the amount of the one or more enzymes is from 0.001 to 8% by weight.
