The difficulty for the preservation and preservation of anatomical pieces has been a concern in teaching, and research, in the area of Morphology, in addition to the well-known and documented toxicity of formaldehyde. Taking into account this, at the National University of Colombia, tests were carried out on a corpse, in a very poor state of conservation (it was preserved in formaldehyde for more than 3 years), with the aim of improving handling and documenting recovery. To achieve this, cross-sections were made from the head to the pelvis. The preservative solution based on sodium chloride, sodium nitrate, benzalkonium chloride, alcohol, glycerin, water, eucalyptus essence and formaldehyde was then prepared at very low final concentration. The cuts are placed in immersion, and their preservation conditions were tracked with weekly photographic record and completed with a final immersion in hydrogen peroxide. 10 weeks after fixation are kept in adequate preservation conditions, retaining flexibility, the muscles show a similar appearance to the observed post-mortem, the bone maintains its white color, no changes in skin coloration due to external rotting processes and most of its internal organs are preserved under adequate conditions. The conservative fixative solution has shown good results in fixation and preservation in tissues, without the irritating or toxic effects for handlers, and hydrogen peroxide visibly improves the appearance of the color of the pieces by creating together with the solution a recovery of almost 60% of the anatomical piece
