What does the presence of formaldehyde in embalming fluid primarily achieve?

The presence of formaldehyde in embalming fluid primarily achieves the preservation of tissues. Formaldehyde acts as a potent preservative that effectively inhibits the decomposition process by cross-linking proteins in the body. This action prevents the bacteria and enzymes that contribute to decay from functioning properly, thereby extending the period during which the body can be viewed and memorialized.

While formaldehyde does have other effects, such as potentially affecting the appearance of the skin, its primary purpose in embalming is preservation. It is crucial for maintaining the integrity of soft tissues, which is essential for funeral services and the overall respectful treatment of the deceased.
