In arterial fluids, glycols primarily serve as what?

Glycols, such as ethylene glycol and propylene glycol, are primarily used in arterial fluids as humectants. Their main function is to retain moisture within the tissues during the embalming process, which helps to prevent dehydration and maintain a more lifelike appearance of the deceased. By allowing the tissues to retain moisture, glycols facilitate better preservation and can also enhance the distribution of other embalming chemicals throughout the body.

The presence of glycols contributes to the overall effectiveness of the arterial fluid by working in conjunction with preservatives and other components. While dyes are added to arterial fluids to provide coloration, and some agents have disinfectant properties, the primary role of glycols remains centered around moisture retention and humectancy in the embalming process.
