What is the primary chemical used in embalming fluid?

• A. Formaldehyde
• B. Glutaraldehyde
• C. Alcohol
• D. Chloroform

Answer: (A)

The primary chemical used in embalming fluid is formaldehyde. This compound is a colorless gas at room temperature and is highly effective in preserving biological tissues. It acts as a potent preservative by cross-linking proteins, which helps to stabilize and protect the body from decomposition after death. Formaldehyde is chosen for its ability to effectively deter microbial growth and slow down autolysis and decay, making it an essential component in many embalming fluids.

While glutaraldehyde and other chemicals can be used in various embalming practices, formaldehyde remains the most widely recognized and used agent due to its long history of effectiveness and its established role in traditional embalming protocols. Other options, such as alcohol and chloroform, are not suitable as primary embalming agents due to their different properties and less effective preservation capabilities.
