I was wondering if there was a website or a place that lists all of the currently known e-liquid additives? I currently only know of the following: Sweeteners (sucralose, stevia) Menthyl methyl lactate (PA's Koolada) Ethyl Maltol Malic Acid (PA's Sour Mix) Q-Hit (Throat hit additive) Throat Hit + Diablo Loco (A DV flavor concentrate that adds TH due to SHU rating of 500,000) PGA (Added to thin VG or add throat hit) Menthol Crystals/Liquid Caffeine Herbal Extracts I was hoping that there was a more concise list that showed which vendors carried additives and the effects of the additives on e-liquid. I believe that new DIYers would benefit from a list of additives for eliquid. I gained my list solely from items that I've seen vendors carry during my purchases and I'm sure that there are more out there. For example, I know there are bitter agents and PH balancers available but I have no idea of possible vendors. Similar to the bubbly effect in colas. I've studied carbonation techniques, but I'm unsure if this is a safe thing to do to an e-liquid.
