Our Reed Diffuser Base transforms fragrance and essential oils into high-quality reed diffuser oils. It thins fragrance and essential oils so they flow up the reed easily and provide a bigger scent payoff. Many of our fragrance and essential oils are safe for use in reed diffusers.

Looking for the best performance and the most sustainable diffuser base?
Explore our new CandleScience EcoBase™ Reed Diffuser Solution. Optimized for use with both CandleScience fragrances and essential oils, this base can be used with reed diffusers and other passive diffuser products. 

Find your favorite reed diffuser fragrance by using our Fragrance Oil Finder.

Or, make naturally-scented reed diffusers with our reed diffuser approved essential oil collection.

Are all reed diffuser bases the same?
Absolutely Not! There are two big things to watch for:

1. Flow - Our reed diffuser base flows quickly and easily up the reeds, allowing the fragrance or essential oil to reach its strongest throw potential.

2. Safety - Many states have restrictions on the VOC percentage of reed diffusers. VOC's or Volatile Organic Compounds are compounds that are harmful and create indoor air quality problems. Our reed diffuser base is non-toxic, and VOC compliant in all 50 states, so you can be confident that your reed diffusers meet indoor air quality regulations. This product does not contain DPG.

Great Base!

I love this base, it works great with all of my fragrances. The eco base has a strong odor and this one does not.

this is a great base wish there were more fragrance options to use, and how can we get information on the ingredients for this base so I can label product correctly

Hi Elizabeth! Thanks for your review. For finished diffuser labeling purposes, you are not required to have an ingredients label on diffusers, however, if you choose to include one, you can simply put diffuser base as it is recognized in the US that the individual components are trade secrets. A member of our Support team has also reached out to assist with finding compatible fragrances!

Works well with many other Fragrances that are not Candlescience brand. Best base that I have found and is now the only base that I use.

I’ve been a CS customer for probably about 10 years, ever since their warehouse was in Morrisville NC, down the street from my house. I have tried other companies’ products and have been very disappointed. The CS fragrance oils especially can’t be beat. My experience has been limited to candlemaking until last year when, on a whim, I bought a 16oz bottle of this diffuser base and some containers to try. I read all the advice CS and other customers have offered before getting started and chose a CS FO that they said works well with diffusers. It was one of scents that smells like a Christmas or pine tree, but I forget which one. Following advice I had read, I used the recommended concentration and stirred that solution until my arm was about to fall off and then I stirred it some more. I placed the diffuser in our downstairs bathroom that is near the foyer and was pleased with the throw it produced. It wasn’t incredibly strong, but it was enough to scent the entry of the house if the bathroom door was left open a crack. After a couple of months the scent strength was fading and I wanted something that wasn’t season specific anyway. Unfortunately I didn’t have any base or containers left as I had given it all as Xmas gifts. So I just added another fragrance to the base already in use that I thought would work well with the pine but not smell like Xmas. I used an old CS FO that is discontinued now, it was a Juniper Breeze copycat if you remember that scent from B&BW. Again, I stirred the solution for what seemed like forever, but the results were amazing! Here it is 9 months later and that diffuser is still throwing plenty of fragrance. I haven’t even changed the reeds, although I do flip them upside down occasionally. They’re not CS reeds, they’re just inexpensive fiber reeds from Amazon. What I have learned from all of this is that the fragrance you choose matters a lot. That first Xmas fragrance I used was good but not phenomenal, but the second round was truly impressive. Also, stir it longer than you think is necessary.

Love it!

The ONLY reason I do not give it 5 stars is because there is no ingredient list. I can tell my clients all day that its non toxic and that usually works, but every now and again I get a stickler client that asks pointed questions I cannot answer because I don't know for sure what all is in it.

Other than that, I love this base and use it so much that I am now ordering 5gal jugs at time.
