Stability Test Questions: do you test for UV exposure?
Hello, dear wizards of formulating chemistry. Question: if you are testing for stability, besides temperature, do you normally test for light exposure? Also, when a product says "keep in a cool, dry place" does it mean their stability test was different? And, finally, what are the circumstances for PET? It lasts for a month, so do they keep it warm and cozy or just room temp? Thank you!
