Abstract
Cleaning of milk films by solutions of NaOH is shown to follow the kinetics of a first order reaction. The reaction between solutions containing OH and milk films exhibits a Q10 of 1.6 under these conditions, and the effect of temperature or the reaction rate is linear, at least within the limits of 36 to 82[degree]C. By applying kinetics to detergency, temperature effects can be measured rather than estimated, and compatibility, incompatibility, or complementary interaction of detergent fractions can be detected. Extension of these data will permit weighing factors such as the temperature and hardness of the water, circulation time, turbulence of the solution, the soil to be removed, and the detergent fractions available, so that maximum results can be achieved at minimum expense.
