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
