How long can dimethyl sulfoxide be safely stored in a HDPE "barrier bottle"?

How long can dimethyl sulfoxide be contained in a HDPE barrier bottle without any reaction between the plastic and the solvent? I have read that DMSO is not reactive with HDPE, but I would like to know if anyone has alternative data. I received a shipment of 99.999% pure DMSO, directly from the manufacturer, in specially made HDPE gallon jugs, but I am wondering if I would be well advised to transfer it to glass containers for long-term storage, to maintain purity. Thank you for any insights!


edit: Someone in the comments has suggested I add this information: the intended use of this DMSO is for personal experimentation and research regarding the pain reducing qualities of DMSO, utilizing myself as the test subject.




2 years according to the Aldrich data sheet

Almost indefinitely as long as the temperature is below 60 degrees or so. I have seen vats full of DMSO of Poly propylene FRP construction up for years. Although the one we used is 99.1% and more and not 99.999% but yeah one FRP tank is more than 22 years old and has been filled with DMSO all its like used to make TMSO-B all day everyday.
