As with many skin care products, there are myths surrounding the use of petroleum jelly. Some people may wonder, “Is petroleum jelly flammable”? Although it’s oil-based, petroleum jelly by itself is not hazardous. If combined with a wick of some kind or other flammable material it might burn, or if heated to extremely high temperatures petroleum jelly can give off vapors that are flammable. This is obviously not a concern under normal conditions. Petroleum jelly has a flash point of at least 400 degrees Fahrenheit (closed cup) – this means that to produce enough vapors for the substance to be flammable, the jelly would have to be heated to more than 212 degrees. That’s not going to happen naturally, even in the middle of summer!
