A general knowledge of chemistry is not going to tell you what "tocopherols" or "methyl salicylate" are,
A vague hint? Methyl salicylate would be a methylated salicylic acid (which anyone who has taken organic chemistry has heard of), aka an ester, so likely used for aroma/flavor which would be very common in foods and probably nothing to worry about in an ingredient list (though I have never seen it so I assume you are trying to be clever or it has a more common name?)
Ok, of course had to look it up. Wintergreen, eh. I think my above guess was fairly close. And why? CHEMISTRY! So, do YOU know what an ester is? If not, chemistry would have helped you. If so, chemistry DID help you.
