What is the primary component in embalming fluid?

The primary component in embalming fluid is formaldehyde. This chemical is crucial for the preservation of human remains, as it acts as a strong disinfectant and a tissue preservative. When formaldehyde is added to water, it forms a solution that penetrates body tissues, causing protein cross-linking, which helps to thwart decomposition. This is essential in preparing the deceased for viewing and burial, contributing to both the preservation of the body and the public health aspect of funeral service.

Alcohol, phenol, and glycerin, while they may play roles in certain embalming formulations or processes, do not serve as the primary active agent in the embalming fluid itself. Alcohol can be used for its disinfectant and dehydrating properties, phenol may assist in tissue hardening and disinfection, and glycerin is often employed for moisturizing properties, but none of these alternatives primarily fulfills the role that formaldehyde does in the embalming process.
