Why the base is the biggest %.And why it doesn't matter.

Every essential oil is intensely concentrated — a single drop is enough to overwhelm. So every aroma product on earth, from perfume to vanilla extract to inhalers, dilutes those oils into a neutral, food-grade plant base. The base is odourless, tasteless, and stays in the core. What evaporates at room temperature and reaches your nose is the lighter aromatic oils, not the base. So while the base takes up most of the volume, it's not what you actually smell.

Plant Glycol Base
A clear, odourless plant-derived liquid. The same ingredient used in toothpaste, ice cream, asthma inhalers, and kids' cough syrup. FDA & EFSA-classified as Generally Recognised As Safe (GRAS).
Plant Glycerin Base (E1518)
Made from plant glycerin. The standard food-grade carrier used in chewing gum and beverage flavourings worldwide.
Vegetable Oil / Vegetable Glycerin
Refined, food-grade plant oils. Same family as the oils in your cooking and skincare. 100% plant origin.
Grain Alcohol (Ethanol)
The same food-grade alcohol in vanilla extract, kombucha and perfume. Carries citrus oils. Evaporates instantly.
