An Osmotic Embalming Formula. Hexaphene MA-64 accomplishes much more than preservation alone. MA-64 thoroughly diffuses the viscera with a powerful Hexaphene chemistry that is both unique and unmatched. If menacing C1 Welchii bacteria is present, it is annihilated. Other gas forming or staph culture bacteria is destroyed on contact. As with all the Hexaphenes, MA-64 accomplishes still other highly desirable functions. Swiftly and permanently the whole viscera mass is completely deodorized, sanitized and preserved.
