Art-Sorb

Does anybody know whether Artsorb silica gel really contains lithium
chloride?  Christoph Waller's website <URL:http://www.cwaller.de>
has a MSDS which lists lithium chloride as one of the constituents,
but I have never heard of this before.  I have some old data sheets,
but it's not mentioned there.  All technical information has
vanished from the Fuji Silysia website:

        english/product/humidity_control_silica/art_sorb.html>

Check it out.

Assuming it does contain lithium chloride, does this apply to all
Artsorb products--loose beads, cassettes and sheets?

I'd be grateful for any reliable information.
