Glue sticks

In May 1990 Ellen McCrady referred in the Cons DistList to tests
carried out by the CCI and National Archives on the make up and
stability of Pritt Glue Sticks which made for interesting reading.

I have just been contacted on behalf of a renowned author whose
research texts consist of many tens of thousands of assorted labels
and scripts attached to assorted papers.

My understanding is that the works are of a significant national
importance and that as a result those associated with the  author's
works are increasingly worried about the longevity of this type of
adhesive product being used.

The makers of the glue stick have provided the author's associates
with detail of the composition being 35.49% Polyvinyl Pyrrolidone,
60.99% water, 3.49% Sodium Stearate, 0.3% preservative (being 74.7%
of 4.4-Dimethyloxazolidine, 2.5% of 3.4.4-Trimathyloxazolidine and

>From its composition can anyone suggest whether or not the material
is at risk from this glue stick and has anyone conducted longevity
tests on glue stick products in general.
