According to Smitty Two :
What's medical grade CA? Is that $3 dimestore glue that's been
repackaged and sold for $300? The standard stuff you have around the
house works great for wounds.
Medical grade CA is a different formulation with somewhat more high
grade component chemicals. This shouldn't be a surprise - dimestore
grade CA doesn't perform nearly as well as even "Hot Stuff" does.
According to
http://en.wikipedia.org/wiki/Cyanoacrylate, most regular
CA glue is methyl-2-cyanoacrylate, which degrades fairly quickly
in contact with human tissue and produces formaldehyde. Which is
a pretty strong irritant. Medical CA is 2-octyl cyanoacrylate
which degrades _much_ slower, and won't produce tissue irritation.
The FDA has only approved 2-octyl cyanoacrylate for medical use.
