Diffusers are a beautiful way to create long-lasting fragrance experiences, but the base you choose plays a huge role in how your scent performs. Whether you’re making reed diffusers for your small business or crafting gifts at home, understanding the different types of diffuser bases can help you maximise fragrance throw, longevity, and customer satisfaction.
1. Alcohol-Based Diffuser Bases
Best for: Strong, fast scent throw
Ethanol (Alcohol) based bases are one of the most common options used in diffusers. Because alcohol evaporates quickly, these bases allow fragrance oils to travel up the reeds and disperse into the air rapidly, giving you a strong, instant scent throw.
Pros:
-
Quick fragrance release
-
Works well in larger spaces
-
Compatible with most fragrance oils
Cons:
-
Shorter lifespan due to faster evaporation
-
Not always eco-friendly, limited with shipping options
-
Can be drying on surfaces if spillage occurs
2. Water-Based Diffuser Bases
Best for: Subtle, clean, and low-tox formulations
Water-based diffuser bases are perfect if you’re looking for something gentler and less volatile. They’re typically paired with solubilisers to help fragrance oils disperse evenly, offering a lighter and softer scent throw.
Pros:
-
Low-tox and safer for families and pets
-
Eco-friendlier option
-
Less risk of staining surfaces
Cons:
-
Requires proper formulation to prevent separation
-
Generally produces a softer scent throw
3. Eco-Friendly Diffuser Bases
Best for: Sustainable and long-lasting diffusers
Eco diffuser bases, like Wickii’s Eco Base Diffuser, are growing in popularity thanks to their high performance and environmentally conscious formulations. These bases are made from renewable resources and are designed to maximise fragrance delivery while lasting longer than traditional alcohol-based options.
Why Wickii’s Eco Base Stands Out:
-
Made from a proprietary eco-friendly blend
-
Offers a 30% longer lifespan compared to alcohol-based bases
-
Delivers a powerful scent throw without compromising on sustainability
-
Recommended fragrance load up to 30% for maximum flexibility
Pros
-
Made from renewable resources, biodegradable, and low in VOCs.
-
Offers a noticeable and consistent fragrance diffusion, even in larger spaces.
-
Engineered to evaporate more slowly than alcohol-based bases.
-
Performs well with both natural and synthetic fragrance oils.
Cons
-
Usually more expensive than DPG or alcohol-based options.
-
cent may take slightly longer to bloom compared to fast-evaporating alcohol bases.
-
Evaporation rates can be influenced by room temperature and humidity levels.
4. Glycol-Based Diffuser Bases
Best for: Consistent and controlled scent release
Some bases use glycols, such as dipropylene glycol (DPG), to provide a steady and balanced scent throw. These bases are thicker than alcohol-based options, so they evaporate more slowly and are often chosen when longevity is key.
Pros:
-
Slow, even evaporation
-
Extended diffuser life
-
Suitable for smaller rooms and offices
Cons:
-
May require specific reeds for optimal performance
-
Slower initial fragrance release
-
Not considered eco-friendly — it’s petroleum-derived
Final Thoughts
The best choice comes down to your priorities — whether that’s budget, sustainability, performance, or fragrance impact. Testing both bases with your chosen fragrance oils is the best way to see which one suits your products and customers.
