“…Therefore, it was decided to try extraction with running fluid by percolating the serous body cavities. As the present ceiling value for formaldehyde in air (0.4 gg/1) is below the limit of detec tion with the Drager multigas detector used in previous experiments [Bjorkman andChristensen. 1982: Frolicli et al.…”

Formaldehyde was removed from embalmed animal cadavers by pumping ethanol (20%) through the pleural and peritoneal cavities of 4 goats, 4 cows and 4 horses. The goats were percolated intermittently for 7 days and the large animals continuously for 72 h. Just after opening the body cavities, samples of air close to the organs were collected and analyzed for formaldehyde using a spectrofluorimetric method. The concentration of formaldehyde in the air samples was in goats 0.45 ± 0.44 µg/l (mean ± SD), cows 0.42 ± 0.29 µg/l and horses 0.43 ± 0.25 µg/l.

“…Bjorkman and Christensen [1982] extracted formaldehyde from fixed animal tissue by immersing whole small animals or parts of large animals in dilute (20-25%) ethanol. After 2-3 months, no formaldehyde (< 0.5 ppm) was detected in the ambient atmosphere, in which the extracted specimens were exposed.…”

Excess formaldehyde was extracted from embalmed animal cadavers by vascular perfusion or combined perfusion and percolation with 20% ethanol. The perfusion was undertaken through a carotid artery and the percolation through the serous body cavities for 1–2 h. Nineteen goats were perfused once and one goat and three cows were perfused and percolated twice a day for 3 days. The extracted cadavers were stored in 20% ethanol or in a freezer at –20°C.The mean value of the atmospheric concentration of formaldehyde after extraction was 0.27 ± 0.05 mg/m³ for goats and 0.39 ± 0.12 mg/m³ for cows.

“…However, ethanol in high concentrations is expensive, flammable, and evaporates rapidly.In addition, most tissues were subjected to excessive hardening and loss of natural colours in these concentrations. In lower concentrations the antimicrobial action of ethanol may be unsatisfactory [19].…”

Formaldehyde is not just a human carcinogen but the cause of many other unwanted hazards; respiratory distress, red eyes, etc. Occupational health authorities throughout the world are therefore likely to increase the strictness of regulations for the use of formaldehyde within anatomical disciplines.Aim: This study evaluates the effectiveness of Phenoxetol (Phenoxyethanol) as suitable alternative to formaldehyde for long term preservation of cadavers.Results: The soft consistency, colour and flexibility, of cadavers preserved in Phenoxetol, was found to be suitable for dissection & demonstration purposes. Conclusion:Phenoxetol proves to be a viable replacement of formaldehyde.Its efficacy as a preservative and fixative is supposed to be better than formalin. In addition to avoiding the well-known hazardous effects of formaldehyde, the use of Phenoxetol also prevents the pungent and irritating smell associated with formalin and other local and systemic manifestations of its toxicity.
