    I’ll try and keep this short, but I also want to provide enough info so you guys know where I’m coming from and where I’m stuck.

    We have a small company that started making candles. We expanded into diffusers, but ran into the issue of a lot of oils simply not working in reed diffusers.

    We buy our oils from various providers in the US, but I understand these are basically middlemen, not the chemists who actually formulate the fragrances.

    We were approached at one event by a famous international fragrance manufacturer and we’ve started to work with them, trying to move all our fragrances over to theirs.

    We’ve so far switched one scent over to them, and they told us the oil they gave us for reed diffusers is water-based. We want to start making other products like room spray, and my guess is that these are typically water-based as well?

    My question is, are big brands really using water-based fragrance oils in their products (diffusers, room sprays)? Or are they using oil-based fragrance oils with an emulsifier to help blend the oil with the water in the spray? I’m struggling to find information on water-based vs. oil-based that goes beyond just Reddit posts, so if there’s somewhere you can point me, I’m happy to go read up on this myself.

    Thanks!
