Prosector
Generally, the risks to prosectors are low. Cadavers used for teaching purposes are embalmed before they are encountered by a prosector and students. Embalming fluid usually contains formaldehyde, phenol, Dettol, and glycerine which disinfect and kill pathogens within the cadaver. With exposure to embalming fluid, tissues and bodily fluids, such as blood, become fixed. Prosectors and students working with embalmed cadavers must always wear protective gloves, however this is more for protection against the harsh chemicals used in embalming such as formaldehyde and dettol which can cause moderate to severe skin irritation.
Glazing agent
Natural glazing agents have been found, usually in plants or insects. In nature, the agents are used to keep the moisture in the organism, but science has harnessed this characteristic by turning it into a glazing agent that acts as a coating. The glazing agent is made up of a substance that is classified as a wax. A natural wax is chemically defined as an ester with a very long hydrocarbon chain that also includes a long chain alcohol. However, in a wax there have been many different chemical structures that can be included in a definition of a wax, such as: wax esters, sterol esters, ketones, aldehydes, alcohols, hydrocarbons, and sterols.
