Which substances are known to enhance the ability of embalmed tissues to retain moisture?

Humectants are substances that help retain moisture in embalmed tissues. They work by attracting and holding water molecules, which is essential in preventing the tissues from becoming overly dry during the embalming process. When humectants are incorporated into embalming fluids, they enhance the moisture content of the tissues, leading to better preservation and appearance of the body.

Preservatives focus primarily on inhibiting microbial growth and slowing down decomposition, but they do not specifically aid in moisture retention. Antimicrobials help to reduce or eliminate bacteria and other pathogens in embalming fluids but do not contribute directly to moisture preservation. Surfactants are agents that lower the surface tension of liquids, allowing better penetration of embalming chemicals but do not retain moisture in the same way humectants do. Thus, humectants are uniquely suited to the function of enhancing moisture retention in embalmed tissues.
