Description
Formaldehyde is common chemical used in industrial processes as well as the research environment. Pure formaldehyde is a gas at room temperature but is commonly found as a 40% (by volume) aqueous solution, known as formalin. Commercially available formalin may contain methanol as a stabilizer. It is used in the process of embalming.
Embalming is a process of chemically preserving tissues with chemical fixatives such as formalin or other fluids that can interfere with toxicological analyses. Common ingredients of embalming fluids are formaldehyde, methanol, sodium borate, sodium nitrate, glycerin, coloring agents, and water.
