i really dont think menthol is a hydrocarbon at all..its similar to a organic compound taken out of mint
THey should never have invented Menthol...its a derivative of hydrocarbons..no long term studies have be done on it to search for cancer beginnings.
Menthol's ability to chemically trigger the cold-sensitive TRPM8 receptors in the skin is responsible for the resourcefully known cooling sensation that it provokes when inhaled, eaten, or applied to the skin.[1] In this sense it is similar to capsaicin, the chemical responsible for the spiciness of hot peppers (which stimulates warmth sensors, also without causing an actual change contained by temperature).
