- Detergent compositions containing proteases are well-known in art. By using a protease in a detergent, it is possible to hydrolyze the proteins, present in stains and soil on the clothes, to such a degree that they become readily soluble in water.
- the present invention is based on the unexpected finding that in a "compact" matrix containing a polymeric dye transfer inhibiting agent and a non-alkylbenzene sulfonate surfactant system, the detergency performance of a protease having an isoelectric point below 10 outperforms other proteases having an isoelectric point of higher than 10 such as Savinase®, Opticlean® , Maxacal®, Purafect®, and Esperase®.
