- 6. The liquid aqueous detergent composition according to claim 1 wherein the proteolytic enzyme is selected from the group consisting of bacterial serine proteolytic enzymes obtained from Bacillus subtilis, bacterial serine proteolytic enzymes obtained from Bacillus licheniformis and mixtures thereof.
- 7. The liquid aqueous detergent composition according to claim 2 wherein the proteolytic enzyme is selected from the group consisting of bacterial serine proteolytic enzymes obtained from Bacillus subtilis, bacterial serine proteolytic enzymes obtained from Bacillus licheniformis and mixtures thereof.
- 8. The liquid aqueous detergent composition according to claim 1 wherein the composition further includes a performance enhancing amount of a detergent compatible second enzyme selected from the group consisting of lipase, amylase, cellulase, and mixtures thereof.
- 9. A liquid aqueous detergent composition comprising:
- (a) from 1% to 80% of a detersive surfactant;
- (b) from 0.0001% to 1.0% of active proteolytic enzyme or mixtures thereof, and
