How polyethylene glycol - 600 will react, when heated at 60 degree C?

21 July 2020 0 7K Report

I am heating the PEG 600 at 60 degree C with mixture of sodium mono carbonate and water to make gel out of it, but after heating @ 60 C for 2 months PEG molecules are forming CLUMPS and appearance look like jelly. Is this because of over heating PEG or due to undissolved particles of PEG & sodium mono carbonate with water??
