What substance is not used in hypo embalming a severed portion of the body?

The process of hypo embalming involves injecting a preserved substance into a severed portion of the body to preserve it. Paraformaldehyde is a form of formaldehyde that is commonly used in embalming practices due to its effectiveness as a preservative and disinfectant. However, when it comes to hypo embalming, paraformaldehyde is not typically utilized because there are other substances that serve better purposes for this specific technique.

Ethyl alcohol is often used in hypo embalming as it helps to preserve tissues and adequately prepare the area for preservation. Glycerin is valuable in hypo embalming as well, as it helps to maintain moisture and prevent the desiccation of tissues. Formaldehyde is commonly employed in various embalming processes for its strong preservative qualities; however, it's likely that other substances are preferred for effective hypo embalming. Thus, paraformaldehyde, while useful in other contexts, is not a substance that is typically utilized for hypo embalming of a severed body part.
