A. Yes. For pharmaceutical and medical device manufacturing it is required that there be set residue acceptance levels for potential residues such as the active drug, excipients, degradation products, cleaning agents, bioburden and endotoxins.
Effects of Increased Tergazyme Concentration
Q. Currently we allow parts to soak in 1% Tergazyme® enzyme-active powdered detergent overnight. If we were to increase the concentration to 3-4%, do you think it would increase the stability of the solution being active for a longer period of time?
A. You will both increase the rate of auto-digestion due to increased enzyme concentration
Removing Eudragit from Equipment
