Reed Diffuser Base 16oz and 5 lb. bottles
Choose a Variant

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.

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.

Excellent Reed Base

This reed base is amazing and we are selling our reed diffusers like crazy!
The key to getting the odor from the base to disappear is to stir for 3-4 minutes.
Once the fragrance oil is completely bound to the base, all you smell is the fragrance!

Best Diffuser Base

I don’t know why all the 1 stars… this base works amazing! I use a 5 to 1 ratio and I get nothing but 5 stars on my diffusers!

Works Great

This base works just fine. It takes a very strong fragrance to work with a reed diffuser base to begin with, so I expected that and now just check the IFRA restrictions on how much fragrance can be used. Also, if you are using too much fragrance, you can clog the reeds, so be careful to not do that. If you are using fragrance from another company that has a really thick carrier base, I would not use that with a reed diffuser as it can also clog the reeds. I do agree that it's disappointing to not have an option with the large container where it is actually full. I enjoy reed diffusers in my own home and my customers seem to enjoy the look of your silver containers and this base with natural reeds. Thank you Candlescience!

Very very disappointed

I use this and the last batch I bought did not work. At first I thought it was the Reed, I used another Reed and it did not work. I have wasted money testing different reeds but non is working. After my testing I see it’s the base. I have been using this base and getting the best throw that feels a big living room. 8 customers returned this for no throw. This is a financial nightmare for me. I am soo upset I will never buy from candle science again because this is just a nightmare.

Very disappointed

I purchase the reed diffuser base 16 oz on a monthly basis and decided this time around to purchase the jug instead of the 16 oz. I received my order, and the jug was not fully filled. I'm very disappointed I am unaware if this is the norm when ordering jug sizes if so it will be my last time.

Something went wrong

I followed the instructions provided. Unfortunately, I have now wasted my expensive fragrance oil that I used to test out this base. I am so sad that it is not working out for me. I tried it with two different fragrance oils that are compatible with reed diffusers, and they keep coming out with a chemical smell and none of the fragrance oils are sticking at all to the base. I would kindly like to request some feedback on these. I am aware that I will not be able to return/refund, but I would like to provide my honest feedback on this base.

There’s Something Wrong

I recently switched from another brand and I’m not sure what’s going on, but there’s no smell with this base. It completely neutralizes any fragrance oil I add to it. I’ve had so many customers contact me about defective diffusers. I’m having to replace all of them and the current stock I have. It’s a financial nightmare. If you’re thinking of using this I’d recommend getting the small bottle to test instead of trusting this product is of the same standards as all the rest.

I just learned something!

I just learned something that most of you have probably already figured out, but in case you are a newbie like me...There are a list of Candlescience fragrance oils that are compatible with the diffuser base on the site. I made several diffusers...some where amazing and some were terrible at throwing any scent. I couldn't figure out why and just kept trying random scents I loved. I now realize it's because only some of these are compatible with the bases. It turns out (duh!) that the ones that throw a great scent are the ones listed as compatible and vice versa...if they aren't listed they don't seem to throw a scent. Just thought I would share this in case I'm not the only one who hadn't realized!

Odd chemically smell?

Not sure if I am doing something wrong, ( followed the directions!) but my blends I made with this smell chemical-y after 3 months bottled up. The opened bottle of diffuser base I used to make them also smells, and it has nothing in it except for the base. Does this deteriorate with time or change? Was just wondering... Between vendor fairs and not sure if I can or should use this in my products or not!
