What is a common chemical used as a preservative in embalming fluids?

• A. Alcohol
• B. Formaldehyde
• C. Acetone
• D. Phenol

Answer: (B)

Formaldehyde is commonly used as a preservative in embalming fluids due to its effective ability to kill bacteria, fungi, and other microorganisms. It also has strong tissue fixation properties, which help to preserve the body by coagulating proteins and preventing decomposition. This chemical interacts with the tissues in such a way that it helps maintain the body’s natural appearance for viewing and memorial services, making it a staple in the embalming process. Its effectiveness and historical use in the field of mortuary science solidify its role as the primary preservative in many embalming fluids.

Alcohol, acetone, and phenol have different uses in various applications, but they are not as commonly utilized as formaldehyde for preservation in embalming. Alcohol might serve as a solvent or disinfectant but lacks the same level of fixation properties. Acetone is typically used as a solvent in many chemical processes, while phenol, although sometimes used in older embalming formulations for its antiseptic properties, is not as widely used as formaldehyde due to potential risks and limitations.
