Cleaning Proteins: pH and Temperature
We run our caustic cleaning at pH 10-10.5. However, the specifications say the nominal pH of a 1% Tergazyme solution is 9.5 Are we compromising cleaning proteins / enzyme performance by using the higher pH and running as part of a caustic cycle? Can we run it at 110F or should we be lower?
Clean in Place “Hacks” for Water Spots
A: A two-step cycle with a base followed by an acid, whether it be CIP cleaning or in a large scale liquid dispensing system washer, is a robust and, when needed, is a recommended process. Water spots typically occur because of two main mechanisms….
Going Green with Cold Cleaning
Q: We are a large biotech and in an effort to go green with our cleaning, we are exploring cold cleaning (cleaning with cold water) using your detergents. A: Cold cleaning is a very reasonable approach for energy conservation, and in short, its effectiveness depends on the details of the application.
Cleaning Stressed Polycarbonate
Q. In the past you have recommended a specific detergent type detergent for our sensitive plastics (stressed polycarbonate), mentioning that it does not have a surfactant. Can you elaborate for us why?
Types of Surfactants
Q. What are the different types of surfactants? A. Anionic surfactants, Nonionic surfactants, Cationic surfactants, Amphoteric surfactants.
