Super Glue

Is there a difference in the super glue used hospitals and the glue sold in stores?

[Hi_Ho_Sliver]

I have heard them say there is?? but don't know and really doubt it...just my opinion!

There are differences;

The superglue used in hospitals is FDA approved for use on humans.

The price, the medical variety is 'single-use' at $20.00 each.

Also the formulation, store bought is typically 'Ethyl' cyanoacrylate which was developed in the 1950s; the medical version is 'Octyl' cyanoacrylate developed in the 1990s.

Rick,
I'm impressed you seem to have a wealth of knowlege on all these things. What is your background if you dont mind me asking?

At my day job, I am a windtunnel/Developmental inspector for the Boeing Co.

My knowledge in the area of medical adhesives is a result of looking for new products for my catalog. I was also interested in the toxicity of 'off-the-shelf' superglue.

By the way, 'ethyl' is the same hydrocarbon which forms the base for alcohol.

Now, back to work. :P

This is neat, a wonderful site for new carvers
Thanks

Come back Rick, I'm curious, even though they are 'different' can they both be used (safely) for the same job? Like glueing us back together??
Figure superglue can't hurt our systems any, I don't know anyone that can use the stuff and not get it on themselves somewhere (or is it just klutzy me??) : Callynne

Can't remember where I heard it but, super glue was originally developed during the Viet-Nam war to use in the field on the wounded. Can't say that's fact, just what I heard.

The FDA has only approved one form of Superglue for human use 'Octyl'.

'Butyl' has been used outside the U.S. on humans for over 30 years, but is only used by Vets inside the U.S.

'Ethyl' and 'Methyl' is what is sold over-the-counter, and Butch is correct, it was used in Nam on humans. Â*The primary use was for putting livers back together; because it is activated by moisture, it worked very well.

The problem with the adhesive developed in the 50's is its brittle properties and the chemicals released during breakdown.

The new formula adds a plasticiser and a stabilizer which gives it much more flexability. Â*While also reducing the toxic nature of the formula.

I do not recommend anyone use superglue on cuts, but I find it preferable to bleeding. Â*

Interesting thread!!!!
