What is a chemical that increases the ability of embalmed tissue to retain moisture?

A humectant is a chemical that enhances the ability of embalmed tissue to retain moisture. In the context of embalming, humectants are important because they help prevent desiccation or drying out of tissues, which can occur during the embalming process due to the use of various chemicals that can lead to moisture loss. By retaining moisture, humectants contribute to the preservation and presentation of the body, allowing embalmers to maintain a more lifelike appearance for a longer period.

Moisturizers are typically used in cosmetic applications or skincare products to hydrate and soften the skin but are not specifically designed for embalming tissues. Fixatives are chemicals that are used to stabilize and preserve biological tissues by solidifying their structure, but they do not have the moisture-retaining properties of humectants. Preservatives are substances used to prevent decay, but their primary purpose is to inhibit microbial growth and autolytic processes, rather than enhancing moisture retention. This distinction is essential in understanding the role of humectants in the embalming process.
