Hexamine

Hexamine ((CH₂)₆N₄) is a chemical created by the reaction of 6 moles of formaldehyde and 4 moles of ammonia . It is crystalline and white in appearance and is used both for commercial and recreational purposes. Particle size ranges from 80–800 micrometres and it melts at 270 degrees C.

Hexamine can be absorbed through the skin, and some people are allergic to it. This usually only manifests as a rash.

It is used in rubber and textile adhesives, fuel tablets, the photographic industry, the explosives industry, a corrosive inhibitor, as a protein modifier, as a reagent in chemical analysis, and in the production of deodorizer and hair fixers, among many other uses.
