The invention relates to a remains decay-preventing composition, a preparation method and application thereof. The remains decay-preventing composition comprises the following components in proportion: 0.1 to 5 volume portions of
isothiazolinone compounds, 5 to 30 volume portions of dibastic
alcohol, 3 to 30 volume portions of
glycerol, 5 to 30 volume portions of
alcohol, 5 to 50 volume portions of
hexanol, 0 to 15 weight portions of nipagin esters, 1 to 15 volume portions of
dimethyl sulfoxide, 0 to 2 weight portions of
ethylenediamine tetraacetic acid disodium salt, 0 to 10 volume portions of
acetic acid, 0 to 15 weight portions of urotropine, 1 to 10 volume portions of
plant extract and 0 to 15 volume portions of
purified water. By pouring
preservative into aortas and injecting the
preservative into abdominal cavities, thoracic cavities, pharyngeal cavities and cranial cavities, the composition plays a rapid effective role in preventing remains decay. The decay-preventing composition has the advantages of broad-spectrum
antibacterial property, fast action, good compatibility with
enzyme and
low toxicity, and is particularly applicable to the decay prevention of the remains in humid and other environments.
