John,

Just an aside...I would caution you about using Tween to correct problems with wrinkles.  The surfactant did correct microchatter problems , but it
did increase micro-compression problems, especially in some glandular structures.

Subject:  Tween 20


Hi everyone:
     We are about to try using Tween 20 (polyoxyethylene sorbitan
monolaurate) as a surfactant-soak for tissue which commonly displays
wrinkles. The MSDS from SIGMA discloses no hazardous identification
information, though they do mention first-aid measures for skin absorption,
inhalation and the like. The first-aid warnings are pretty intense (wash for
fifteen minutes with copious amounts of water if skin contact occurs). I
know all MSDS warnings are similar in this regard, but I'd like to know what
other labs' experience with this chemical is, and how you all work with the
chemical. Further, what do you do to discard the chemical and its aqueous
residue? Our local waste disposal facility isn't able to offer much help
with this kind of chemical disposal (they have no experience with the
chemical, and there are no local laws regarding it), so I'm just wondering
what others are doing out there.
Thanks for your help,
