Thorol is a mild scented 32 index cavity fluid with a reliable formaldehyde base. Its pleasant faint oil-of-wintergreen odor is achieved by combining formaldehyde with another chemical in loose formation. When the fluid is exposed to tissue in the body, the formaldehyde is freed for preserving action.

Historically, formaldehyde-based cavity fluids out-perform other types because the vapor pressure of formaldehyde assures maximum penetration.

Thorol should be used full strength without diluting for cases where excessive putrefactive gases have already formed in cavities. In cool climates for normal deaths, and where no unusual amount of gas is present, 16 ounces of water may be added to each concentrated bottle of Thorol.

One bottle of Thorol is usually sufficient to preserve the cavities of bodies up to 150 pounds. Where abnormal conditions exist, sufficient Thorol should be used to insure thorough distribution and saturation.
