Triacetin is a flavor carrier used widely throughout the Food Industry.
It has been rated as GRAS (generally recognized as safe),
and inhalation tests have shown no outstanding issues.

However, it is not as water soluble as propylene glycol, and
it can separate out in some blends.
We recommend that you experiment with small amounts before purchasing
in large sizes, just to see if it will work with your application.

Please feel free to call us with any questions.
