What's the difference between fragrance oil, essential oil, and flavor oil?

Fragrance oil, essential oil, and flavor oil are often confused, but they serve distinct purposes and are not interchangeable.

Fragrance oils are designed for scent applications — candles, soaps, diffusers, and body products like lotions and sprays. They are not edible. Depending on the specific product, fragrance oils may be alcohol-soluble (best for sprays and perfumes) or oil-soluble (best for lotions, body oils, and wax-based products), so it's worth checking which type you need before purchasing.

Essential oils are natural distillates derived directly from plants and are also primarily used for scent. While some essential oils have food-grade applications, this is the exception rather than the rule and requires explicit approval for ingestion — don't assume an essential oil is food-safe simply because it comes from a natural source.

Flavor oils are formulated specifically for taste and are the correct choice for anything that will touch the mouth — lip balms, lip glosses, edible products, and oral-care items. If your application involves ingestion or lip contact, always reach for a flavor oil or flavor extract, never a fragrance oil.

The simplest rule: food or lips = flavor oil; scent only = fragrance oil.
