What is the process of injecting a diluted preservative embalming fluid with supplemental chemicals called?

The process described in the question refers to waterless embalming. This technique involves using a diluted preservative embalming fluid mixed with additional chemicals. Waterless embalming does not rely on water to achieve the desired preservation and sanitation effects, which differentiates it from traditional methods that typically involve the use of water as a significant component in the embalming process.

The effectiveness of waterless embalming lies in its ability to create a more efficient and sometimes quicker procedure, especially when dealing with bodies that have already decomposed or when fluids are less desirable. As no additional water is used, the risk of dilution of the preservative is minimized, which can help maintain the potency of the active ingredients in the embalming solution.

Waterless embalming is increasingly used in certain settings where the preservation process requires a more intensive approach without the complications that water can introduce, such as excess fluid or potential for further decomposition. In contrast, other types of embalming listed do not specifically describe the withdrawal of water or the use of supplemental chemicals in the same way that waterless embalming does.
