For something labeled "extremely flammable", setting fire to my alcohol based hand sanitizer gel was dead dull boring. Yes, it burns. But it doesn't lit easily and it doesn't burn very hot. I was unable to lit it with a fire steel, I needed open flame from a lighter. It improves quite a bit if you soak some cotton balls - but petroleum jelly cotton balls works a hundred times better.

As always, your mileage may vary, your local brand may be better and so on. Test it before you depend on it.
