Reed diffusers are a popular way to scent a room and can be made at home. Many recipes for reed diffuser liquid include alcohol, such as vodka or rubbing alcohol, as a binding agent to help the oil mix with water. Alcohol evaporates more quickly than water, making it ideal for drawing oils up through the reeds. However, some people find that the smell of the alcohol is too strong and prefer to use an emulsifier like Polysorbate-20 instead. Others opt for a purely oil-based diffuser liquid, which fills the space with a concentrated aroma.

What You'll Learn
Alcohol helps bind oil and water
Although reed diffusers can be made without alcohol, using alcohol in reed diffusers helps bind oil and water. Water and oils do not mix, but alcohol and oil are miscible, meaning they can mix and form an even solution. This means that less essential oil is needed in the diffuser liquid to obtain a suitable volume for reed diffuser bottles.
Alcohol also helps to thin and preserve the mixture for longer. It evaporates more efficiently compared to oil or water-based fragrances, which can result in a faster and stronger fragrance throw. However, this can also be a disadvantage, as the alcohol may evaporate too fast.
There are a few different types of alcohol that can be used in reed diffusers, including vodka, rubbing alcohol, and perfumer's alcohol. It is important to note that the type of alcohol used can affect the scent of the diffuser, as some alcohols have a stronger odor than others. For example, rubbing alcohol has a stronger odor that may affect the scent of the diffuser.
When making a reed diffuser with alcohol, it is recommended to use a combination of alcohol, water, and essential oil. The exact ratios may vary depending on the recipe, but generally, about 20-30 drops of essential oil are used, along with an equivalent amount of an emulsifier like Polysorbate-20. This mixture is then added to a bottle or container using a funnel, and the reeds are placed inside.

Alcohol evaporates faster than water
When it comes to reed diffusers, a common recipe for the diffuser liquid involves mixing essential oil and alcohol. This is because alcohol and oil are miscible, meaning they can mix and form an even solution. This allows for the use of less essential oil, which is beneficial as these oils tend to be expensive.
However, one drawback to using alcohol in reed diffusers is that alcohol evaporates faster than water. This means that even if the alcohol "climbs" up the "channels" in the reed diffuser sticks, it may evaporate too quickly to effectively diffuse the fragrance. This is due to the molecular structure of alcohol, which results in weaker hydrogen bonding compared to water molecules.
Water molecules, with their two hydrogen atoms bonded to oxygen, can form up to four hydrogen bonds with neighboring water molecules. On the other hand, isopropyl alcohol, a common type of rubbing alcohol, has a hydroxyl group (OH) attached to its carbon skeleton. While this allows for hydrogen bonding, the presence of the carbon chain reduces the overall polarity of the molecule.
As a result, isopropyl alcohol can only form weaker hydrogen bonds with fewer neighboring molecules. This weakened hydrogen bonding requires less energy for the alcohol molecules to escape the liquid phase and become a gas, leading to faster evaporation compared to water. Therefore, while alcohol can help mix oils in a reed diffuser, its rapid evaporation may limit its effectiveness in diffusing fragrances over an extended period.

Bamboo reeds are incompatible with alcohol
While bamboo reeds are natural and aesthetically pleasing, they are incompatible with alcohol. Here's why:
Firstly, bamboo reeds are not effective diffusers when combined with alcohol. In one instance, a user attempted to make a reed diffuser with an oil and alcohol mixture, but the aroma failed to permeate the room. They tried using different essential oils, but the results were disappointing. This suggests that bamboo reeds may not be the best choice for diffusing fragrances when alcohol is present.
Secondly, alcohol can affect the scent of the diffuser. Rubbing alcohol, in particular, has a strong odour that can alter the intended fragrance. This may be undesirable, especially if you are aiming for a specific aroma. The scent of the alcohol may overpower the fragrance you wish to diffuse, resulting in an unpleasant or unexpected blend.
Additionally, some people choose to avoid alcohol for personal or health reasons. If you are creating a product for a wide range of consumers, it is important to consider that some individuals may prefer alcohol-free options. By excluding alcohol, you can cater to a broader audience, including those who abstain for health, religious, or personal preferences.
Moreover, bamboo itself can be a source of alcohol. Bamboo beer, or "Bambuzcal," is an alcoholic beverage distilled from the agave plant and infused with bamboo. It is popular in Mexico and Tanzania, showcasing that bamboo can be an integral part of alcoholic drinks rather than a component in their diffusion.
Finally, bamboo offers alternatives to alcohol. Bamboo leaves, for example, can be soaked in hot or cold water to create a refreshing and restorative drink. Bamboo leaf tea is not only tasty but also rich in silica, a trace mineral beneficial for collagen production and connective tissue health. Thus, bamboo provides options beyond alcohol for those seeking healthier choices or unique beverage experiences.

Alcohol preserves the mixture for longer
Alcohol is often added to reed diffusers to thin the mixture and preserve it for longer. It also helps to increase volatility, making the scent more noticeable. However, it is important to note that alcohol evaporates faster than water, which means that the fragrance may not last as long as expected.
Alcohol is not necessary for reed diffusers to function, and there are recipes for alcohol-free diffuser liquids. For example, you can use an emulsifier like Polysorbate-20 to mix oils and water without separation. This results in a diffuser liquid that will climb up the "channels" of the reed diffuser sticks.
Some people may prefer alcohol-based fragrance oils because they evaporate more efficiently compared to oil or water-based fragrances. This means that the scent will be released more quickly and noticeably. However, this also means that the diffuser liquid may not last as long.
Additionally, the type of reed used in the diffuser can affect the performance of the fragrance. For example, bamboo reeds have natural barriers within their vessels that can make it difficult for the fragrance to wick up consistently. Alcohol-based fragrance oils are not suitable for use with bamboo reeds as they can become clogged.
When creating a reed diffuser, it is important to consider the desired balance between the intensity of the scent and how long it will last. Alcohol can help to preserve the mixture and make the scent more noticeable, but it may also cause the liquid to evaporate faster.

Alternatives to alcohol
While alcohol is commonly used in reed diffusers, there are several alternatives that can be used instead. One option is to use an emulsifier like Polysorbate-20, which helps to bring small amounts of oils into a watery environment. This creates a more uniform mixture that can climb up the reeds more effectively.
Another alternative is to use Augeo as a base. Augeo is a clear, odourless liquid that can be combined with essential oils to create a custom fragrance. The recommended ratio is 3 parts Augeo to 1 part fragrance, but this can be adjusted to suit personal preferences.
Using only essential oils or fragrance oils is another option that does not require alcohol. This method fills the space with a concentrated aroma and can be used with reed diffuser sticks or a wood diffuser ball.
Some other alternatives to alcohol include:
- DPG (di-Propylene glycol): This can be used to dilute the fragrance oil and create a thinner base, improving the wicking ability of the reeds.
- Perfumer's alcohol: This can be added to DPG to reduce its viscosity and create a crystal-clear solution.
- Water: Water can be used instead of alcohol to help the oils disperse and create a longer-lasting scent. However, it may not be as effective as alcohol in climbing up the reeds.
- Witch hazel: This has been suggested as a possible alternative, but some users have not found it to be effective.
- Vodka: Vodka is primarily made of water and ethanol, and it can be used as an alternative to isopropyl alcohol in reed diffusers.
