Abstract: The invention relates to a mixture of polyoxymethylene dialkyl ethers (POM) having a specific molecular distribution of n as well as its preparation method. The invention also relates to a composition comprising: a) a mixture of polyoxymethylene dialkyl ethers (POM) having a restricted specific molecular distribution b) at least one biocidal agent c) at least one pro-penetrating agent d) at least one dye e) optionally, another additive and water as diluent, It also relates to a non-therapeutic method of preserving and/or embalming a dead human or animal body using the composition, such as the use of this composition for anatomopathological purposes.
