Home version of Formaldehyde


We have been looking for a home version of formaldehyde or formalin for a science fair project I am doing. I cannot buy either product where I live. I am wondering if there is something, over the counter, or home remedy that I can use as a preservative?

Telling us where you live would be a good start...

I don't know where you live but where I do Formalin is sold for cleaning the toes of sheep and other animals with hoofs.
Might be worth to check it out.

Formalin is no longer used as a preservative if iam correct.
The inet can propably help you out with other options.




What a fine day for chemistry this is.

If you're preserving specimens of some sort, you could try using isopropyl alcohol. I don't know whether it's quite as good as formalin if you need to preserve something for years, but I've used it to preserve bugs for a few weeks and it worked just fine.

Formalin is still quite available for treatment of diseases in koi carp.
A specialist aquarist shop on line should sell it.

I believe 10% ethanol solution is now popularly used to preserve specimens.

"Methylated spirits" (about 90% ethanol adulterated with substances like methanol, pyridine, sucrose acetate, etc., to make it unpalatable for drinking, and usually with a blue dye), which can be bought in supermarkets, can be used to preserve biological specimens.
