Christian,
Triton - 100 as best I can determine is a form of polyethylene
glycol and Merck Index says it is a non-ionic detergent, dispersing agent
and emulsifier.
Tween 20 according to our own Sil Horwitz is (pay attention, there
will be a quiz later!) sorbitan mono-9-octadecenoate
poly(oxy-1,1-ethanediyl) or Polysorbate for short. Merck says it is an
emulsifier and dispersing agent for internal medicines. They sound
similar and I am intrigued by the idea of Triton x-100 as there are quite
a few problems associated with the use of Tween. One is that it grows
mold after a while. I'd like to find a good substitute for Tween.
Perhaps Sil H. can jump in, this is his field of expertise.
