VpCI vapors are not in any way an oil. In fact they are an excellent alternative to corrosion inhibiting oils.
VpCI begins as a powder based chemical which sublimates into vapor. What exactly that chemical is, is a trade secret that we cannot share but I assure you it is not similar in any way to oil.
Interesting fact: many oil pipelines around the world are protected by corrosion inhibiting chemicals that are added to the oil.
