What is the role of glycerin in embalming fluid?

• A. It serves as a disinfectant for tissues
• B. It acts as a humectant to maintain moisture in the tissues
• C. It enhances the odor of the embalming fluid
• D. It accelerates the decomposition process

Answer: (B)

The role of glycerin in embalming fluid is to act as a humectant, which helps to maintain moisture in the tissues. Glycerin has a unique molecular structure that allows it to attract and hold water, making it an effective agent for preserving tissue hydration during the embalming process. This is particularly important because maintaining moisture is crucial for preventing the rapid deterioration of the body's tissues after death, which can be exacerbated by dehydration.

By retaining moisture, glycerin helps to keep tissues pliable and can contribute to a more natural appearance post-embalming. It also plays a role in preventing the tissues from becoming too firm or stiff, which can occur when vascular and interstitial fluids are replaced during embalming with fluids that may lack emollient properties. The use of glycerin thus enhances the overall effectiveness of the embalming fluid by ensuring that tissues are not only preserved but also remain in a condition that allows for better presentation during memorial services.
