Ethyl Maltol is a very pleasant smelling chemical that is used as a flavorant for the food, beverage, tobacco, and fragrance industry.

Ethyl Maltol can be described as having notes of caramelized sugar or cotton candy.
Ethyl Maltol can sweeten/soften sharp flavors in liquid, especially tobacco absolute.
Suggested dilution: Dissolve 1/4 teaspoon of Ethyl Maltol crystals in 10ml of PGA (Pure Grain Alcohol).
Diluted mixture can then be added to your liquid. Start with one or two drops per 6ml of liquid. Add more to soften or sweeten liquid to your taste."
The bottle of FA cotton candy I have lists the ingredients as: Propylene glycol, Ethyl alcohol.
