What is a common preservative agent in embalming fluids other than formaldehyde?

Methanol is often utilized as a common preservative agent in embalming fluids, primarily due to its effectiveness as a solvent and its ability to coagulate proteins. In the embalming process, methanol helps to enhance the penetration of other agents and contributes to the overall preservation of the body by minimizing decomposition. This attribute makes it a valuable component in embalming formulations.

While other substances listed, such as ethyl alcohol and isopropyl alcohol, can be found in certain formulations or used in specific contexts, they are not as prevalent or widely recognized as methanol in standard embalming practices. Acetic acid also has limited use within embalming fluids and is not primarily recognized for preservation, as its main function relates more to pH adjustment rather than acting as a primary preservative.
