Embalming chemicals are a variety of preservatives, sanitising and disinfectant agents and additives used in modern embalming to temporarily prevent decomposition and restore a natural appearance for viewing a body after death. A mixture of these chemicals is known as embalming fluid and is used to preserve cadavers, sometimes only until the funeral, other times indefinitely. Typically embalming fluid contains a mixture of formaldehyde, methanol, and other solvents. The formaldehyde content generally ranges from 5 to 29 percent and the methanol content may range from 9 to 56 percent. In the United States alone, about 20 million liters (roughly 5.3 million gallons) of embalming fluid are used every year.〔Sehee, Joe (2007). (Green Burial: It's Only Natural ), PERC Reports, Winter 2007. Retrieved on 2013-11-06.〕 == How they work == Simply explained, embalming fluid acts to ''fix'' (denature) cellular proteins, meaning that they cannot act as a nutrient source for bacteria; embalming fluid also kills the bacteria themselves. Formaldehyde fixes tissue or cells by irreversibly connecting a primary amine group in a protein molecule with a nearby nitrogen in a protein or DNA molecule through a -CH2- linkage called a Schiff base. The end result also creates the simulation, via color changes, of the appearance of blood flowing under the skin. Modern embalming is not done with a single fixative. Instead, various chemicals are used to create a mixture, called an arterial solution, which is generated specifically for the needs of each case. For example, a body needing to be repatriated overseas needs a higher index (percentage of diluted preservative chemical) than one simply for viewing (known in the United States and Canada as a funeral visitation) at a funeral home before cremation or burial. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Embalming chemicals」の詳細全文を読む スポンサード リンク
