Look on page 6 of the “Glycerin Report” and you will see the results of the content of these chemicals. When power adjustments were permitted, formaldehyde and acetaldehyde levels were higher respectively for 16/19 and 14/19 participants with the use of 6 compared with 18 mg/mL nicotine e-liquid. In particular, polymorphism for ADH3 seems to strongly influence the metabolism of ethanol to acetaldehyde, with ADH 3 This E-Liquid is Acetyl Propionyl-Free Please Note: E-liquid Labeled Acetyl-Propionyl Free means that particular e-liquid DOES NOT contain acetyl propionyl Acetyl Propionyl (pronounces Ah-see-tel Pro-pee-ih-nil) is typically used as a solvent for cellulose acetate, lacquers, paints, inks, and is also used as a starting agent for drugs, dyes, and pesticides.
