Almost all embalming and preservation fluids worldwide in use contain formaldehyde and phenol which are highly toxic compounds that can easily enter the body through the respiratory system and the skin. All F4L-products are phenol-free and contain no or less than 0.4% formaldehyde. Only for the fixation of the body by perfusion a reduced amount of formaldehyde is added to the embalming composition (0,2-0,3% per body weight).
