In or after the process of creating electronic cigarette liquid I have a question on what to use to change the color of the liquid to 'pink / light pink'.
Ingredient
Propylene Glycol / Vegetable Glycerin Ratio = 25/75 Nicotine 3%
Total Base: 25.05ml 31.02 Grams 83.5%
Flavor additive Total: 4.95ml 4.95 Grams 16.5%
Totals: 30ml 35.97 Grams 100%
Looking for possibilities that are safe for human consumption, color pink.
