The DMSO will most probably not be affected = not chemically
altered, but we have found that the containers, PE or PP,
containing 80-100% v/v DMSO do show layering and blisters
but no leaking after storage times of 18 months or more.
It is mainly a visual/sales problem.
The same problem occurs in the PP/PE cap seals of glass bottles.
You, having only a 20% DMSO conc. may not encounter these
problems for the 1st 4-5 years of storage. But, I suggest for you to
contact Crown Zellerbach and other DMSO producers for advice.
