What is the main function of glycerol in embalming fluids?

Glycerol serves primarily as a humectant in embalming fluids. This function is critical as it helps retain moisture in the tissues during the embalming process. By acting as a humectant, glycerol assists in preventing the tissues from drying out, which is essential for maintaining their appearance and texture post-embalming. Additionally, this property aids in the overall preservation of the body by facilitating the even distribution of embalming solutions and enhancing the penetration of other preservatives contained in the fluid.

While glycerol has various uses, such as having properties that can assist in preservation or acting as a vehicle for dyes and disinfectants, its primary role in embalming fluids is to keep the tissues hydrated. This characteristic ensures that the tissues remain supple and less prone to the damage that can occur from dehydration, which is especially important in preserving the body for viewings or memorial services.
