Method for determining the performance of detergents in the removal of proteinaceous soils

摘要

An improved method for determining the performance of detergents in the removal of proteinaceous soils, which centers upon the use as test soil of radiolabelled blood hemoglobin and upon the evaluation of detergency by both light reflectance and scintillation counting measurements. The method is particularly applicable to the determination of the performance of laundry detergent formulations containing enzymes.
