Surfactants

Ensure even distribution of

embalming chemicals throughout the

tissues, aiding in uniform

Water

Acts as a diluent in embalming

solutions, aiding in the proper mixing

and application of embalming

Alcohols

Including methyl alcohol, Methanol,

wood alcohol, ethanol. and isopropyl

alcohol, can be used as a disinfectant

and and as a dehydrating agent.
