AI Thread Summary
Reducing moisture content in polyethylene glycol (PEG) and propylene glycol (PG) can potentially be achieved by applying a vacuum of around 15000 mTorr for 24 hours. This method is relevant for formulations where moisture levels of 4-6% are introduced through ingredients, as this moisture can negatively impact product stability. The discussion references a study on the removal of peroxides in PEG through vacuum drying, highlighting its implications for the stability of biotech and pharmaceutical formulations. The effectiveness of vacuum drying in moisture reduction for PEG and PG solutions is a key focus, with the aim of improving product quality.

Is it possible to reduce moisture content in Polyethylene glycol or propylene glycol by applying vacuum to around 15000 mTorr for 24 hours. If anyone has any idea please let me know

Thank U very much Mr.Douq Huffman. I'm working on a process where 4-6% of moisture is introduced through the ingredients what we add into PEG and propylene glycol but this % of water is detrimental to the product. So by applyin vacuum can I reduce the moisture in PEG and PG solutions

Engineers slash iridium use in electrolyzer catalyst by 80%, boosting path to affordable green hydrogen https://news.rice.edu/news/2025/engineers-slash-iridium-use-electrolyzer-catalyst-80-boosting-path-affordable-green Ruthenium is also fairly expensive (a year ago it was about $490/ troy oz, but has nearly doubled in price over the past year, now about $910/ troy oz). I tracks prices of Pt, Pd, Ru, Ir and Ru. Of the 5 metals, rhodium (Rh) is the most expensive. A year ago, Rh and Ir...
