It is worth mentioning that when using this compound in vaping liquid preparations, you can make your PG flavor concentrate as 8% solution. That is 80g Ethyl Vanillin in 1L PG. Then you can use 2.5ml from this 8% PG flavor concentrate to add up to other ingredients in forming a 100mL vaping e-liquid. This is based on the recommendation of using up to 200 ppm in the flavor liquid preparation, which means 200mg/L = 0.2g/L.
This is why, you should add a 2.5ml of your prepared 8% Ethyl-Vanillin PG flavor concentrate to a 100ml vaping liquid finished product; in order to go along with the recommended 200 ppm concentration.
