incision into the body cavities to treat the viscera. In cases of tissue gas, phenol based products are often used instead. History Prior to the advent of the modern range of embalming chemicals a variety of alternative additives have been used by embalmers, including epsom salts for edema cases, but these are of limited effectiveness and can be chalked up as "embalmer tricks", as the validity of their use has never been demonstrated by professional embalmers or mortuary science programs. During the American Civil War, the Union Army, wanting to transport slain soldiers from the battlefields back home for burial, consulted with Dr. Thomas Holmes, who developed a technique that involved draining a corpse's blood and embalming it with a fluid made with arsenic for preservation. Embalming chemicals are generally produced by specialist manufacturers. The oldest embalming fluid company was founded as the Hill Fluid Company, in 1878, and was then incorporated by Dr. A.A. Bakker, as the Champion Company, in 1880, making The Champion Company 143 years old. Champion was still owned and operated by the Bakker Family until the death of Dr. Bakker's granddaughter, in the late 1970's. Champion still operates today and is still family owned by the Giankopulous Family. They continuously operate today , They are located in Springfiled,OH The Frigid Fluid Company was founded in 1892, followed by the Dodge Company in 1893, with other companies including Egyptian, now U.S. Chemical, as well as Kelco Supply Company (formerly L H Kellogg), Pierce Chemical Company (now owned by The Wilbert Company), Bondol Chemical Company, and Hydrol Chemical Company. There are many smaller and regional producers as well. Some funeral homes produce their own embalming fluids, although this practice has declined in recent decades as commercially available products have become of better quality and more readily available. Following the EU Biocides Legislation some pressure was brought to reduce the use of formaldehyde. IARC Classes Formaldehyde as a Class 1 Carcinogen. There are alternatives to formaldehyde and phenol-based fluids, but these are technically not preservatives but rather sanitising agents and are not widely accepted. However, The Champion Company has always been aware of the safety of the embalmer and created and distributed lower exposure fluids with less HCHO and by the 1990s Champion was the first to create and distribute HCHO Free Fluids. Only The Champion and The Dodge Company sell those fluids. Environmental effects Despite genuine concerns,
