Preservation of human tissue
Embalming solutions for cadaver study differ from institution to institution (and are reportedly somewhat different from embalming for funerals, but I'm not sure of those details). Typically embalming solutions for cadavers meant to be stored indefinitely consist mostly of water with lesser but roughly equal amounts alcohol (usually methanol), gylcerin, phenol, and a smaller percentage of formalin/formaldehyde to prevent mold.

A document from Albert Einstein College of Medicine lists:


Methanol: 11.1%
Glycerin: 11.1%
Phenol: 9.3%
Formaldehyde: 1.9%


If you want to know what your institution uses, you should just ask, and they should be willing and able to tell you.
