Volatility is more about vapor pressure, so how much a compound likes to evaporate, rather than structural components per se.

I couldn’t find any vapor pressure data online , but the boiling temp of oxybenzone is about 70C higher than for benzene, so it’s probably somewhat less volatile.

Yes I am aware, I am implying that the original poster is not. Volatility does not imply constituents. The benzene could easily come from so many places, but the poster decided to pick out volatility as a qualifier? For reasons?
