What is the purpose of borax in embalming fluids?

Borax, or sodium borate, serves primarily as a buffering agent in embalming fluids, which means it plays a critical role in adjusting and stabilizing the pH level of the solution. The pH balance is essential in embalming because it affects the efficiency of the chemicals used in the process, impacting the preservation and disinfection of the body. Maintaining an appropriate pH helps to ensure that the embalming fluid interacts effectively with bodily tissues, preserving them for viewing and delaying decomposition.

In contrast, while other components in embalming fluids may serve different purposes, such as enhancing odor, providing moisture, or altering color, borax specifically contributes to the control of pH. This is crucial in creating a stable environment for the chemicals to function properly and can ultimately influence the overall effectiveness of the embalming process.
