So I made an account to ask a relatively scientific question regarding wintergreen flavor. I can't find anything related to this topic (including scholarly articles) and was hoping for some feedback from someone knowledgeable in chemistry.
Methyl Salicylate is a METHYL ESTER. This means that it can (under the right conditions) decompose into methanol and salicylic acid through hydrolysis. Typically, it is used in very low concentrations as a flavoring due to its relatively high inherent toxicity (LD50=0.5g/kg), and is typically not subject to heating when consumed, or added in the presence of an acid/base catalyst.
My question is; wouldn't methyl salicylate (aka wintergreen) be susceptible to hydrolysis under the elevated temperature, not to mention weakly basic conditions found in an e-cigarette, and therefore be TOXIC due to the methanol it would produce. Even if the quantity produced is very small, this would still have toxic effects as methanol is EXTREMELY poisonous.
This process does require water to be present you may argue! but I remind you there is water in the air flowing through your atty, not to mention the water added to
liquid by some venders…AND the fact that nicotine is a weak base and may assist in catalyzing this reaction!
Let me know what you think! For now, I’m not touching those wintergreen flavours.
