Nope. Our hospital has two kinds, the "normal"
one to which my previous post applies is
colorless. They also have another one,
extra-viscous, which is blue. But when I saw on
the label of the blue one that it contains 80%
Glycerol, I didn't even try that. No idea whether
this is some kind of international color code or
whether it changes from one block to the next.
Alternatively, you may be able to mix it
yourself: Order 1,2 Propylenglycol and extract
the superabsorber from a disposable diaper (unused)....

BTW, apparently KY-Jelly is a brand better known
in some countries than in others, anyway I had to
look it up. The respective Wikipedia article says
"K-Y Jelly's original stated purpose was as a
<http://en.wikipedia.org/wiki/Surgical_lubricant>surgical
lubricant, and it was often chosen by doctors
because of its natural base. " I didn't even know
that surgical lubricants exist, but if such a
thing is still in use today, it might also be an
alternative for immersion. 'Ask your local doctor
or pharmacist if you have any questions or
concerns about using this medicine...'

Happy lubricating

Steffen
