Patent ID: 7670549

Claim:
A liquid detergent concentrate composition comprising: a) 1 to 30 wt.-% of a surfactant system comprising at least two different nonionic surfactants, wherein the first surfactant is selected from the group consisting of a linear alkoxylated fatty alcohol and an oxo alcohol of the formula R 1 -A-OH, wherein R 1 is a linear or branched C 10 to C 16 alkyl or alkenyl group, wherein A is —(OC 2 H 4 ) x —(OC 3 H 6 ) y — or —(OC 3 H 6 ) y —(OC 2 H 4 ) x —, and x is from 7 to 9, and y is from 1 to 3, and the first surfactant has a cloud point at a temperature in the range from 64 to 70° C., and the second surfactant is selected from the group consisting of a linear alkoxylated fatty alcohol and an oxo alcohol of the formula R 2 -A-OH, wherein R 2 is a linear or branched C 12 to C 15 alkyl or alkenyl group, wherein A is —(OC 2 H 4 ) x —(OC 3 H 6 ) y — or —(OC 3 H 6 ) y —(OC 2 H 4 ) x —, and x is from 1 to 3, and y is from 4-6, and the second surfactant has a cloud point at a temperature in the range from 39 to 41° C.; b) at least two different proteases; c) 10 to 70 wt.-% water; and d) an enzyme stabilizer.
