Ethyl Maltol Solutions (5-15%)
Ethyl Maltol (EM) – Common confectionary sweetner used in eliquids to round out harsh upper notes and sweeten sour/bitter flavors. Many know ethyl maltol solutions by the name - Cotton Candy from the Flavor Apprentice. Our solution of EM is concentrated at 15% for ethyl alcohol (SUPER CONCENTRATE), 10% for PG (Industry standard), and at 5% in VG (PG-free). PG can attain a max solubility of ~100mg/mL (10% solution) of EM, while VG can only obtain ~55mg/mL. However, ethyl alcohol is suitable for very saturated solutions of ~150mg/mL and recommended for maximum EM solubility as a carrier solvent. However through us in our formulations, we have found the 15% ethyl alcohol, 10% PG, and 5% VG solutions to be the most stable and usable concentrations. 15% ethyl alcohol and 5% VG solutions are great for those looking to make a true 100% PG-free vape - ethyl maltol is seemingly difficult to find in these solvents :) Recommended dilutions for final end concentrations of EM in eliquid are ~1-5mg/mL (0.1-0.5%) to start, of course adjusting for taste preference. Remember EM doesn’t magically make eliquids ‘pop,’ flavor art takes research!
Upon rapid cooling, ethyl maltol can sometimes crystallize out of solution. If you see a slight amount of particulate in solution, gentle heating should resolublize the ethyl maltol surprisingly well :)
