Aromatherapy is a simple yet effective way to access the associations between scent and memory. Essential oils are commonly used in aromatherapy, and diffusers are a popular method of dispersing the aromatic molecules into the air. However, essential oils do not mix with water, so ethanol or isopropyl alcohol is used as a binding agent to solubilize (dissolve) the oils into the water. The addition of alcohol also helps to eliminate microbial contamination and acts as a preservative. The concentration of alcohol is important, with a minimum of 95% ethanol required for effective solubilization. Vodka can also be used, but it should not be mixed with water as vodka already contains 40% water.

What You'll Learn
Alcohol is a binding agent that helps oil and water mix
Reed diffusers are a great way to disperse essential oils into the air and fill a space with a gentle aroma. They work on the basis of evaporation. Aromatherapy blends slowly travel up the reeds, releasing the essential oils into the air.
Essential oils do not mix with water. Hence, a binding agent such as alcohol is used to help the oil bind with the water. 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.
The type of alcohol used is important. For effective solubilization, the alcohol used needs to contain 95-100% ethanol. The time allowed for essential oils to dissolve also plays a role. Some essential oils will readily dissolve, while others take longer, and some can stay in alcohol and never fully dissolve.
When making diffuser liquid, the essential oil should be mixed with alcohol first, before water is added. This will help prevent separation between the three ingredients.

It helps eliminate microbial contamination
Alcohol is an important ingredient in diffuser oil as it helps eliminate microbial contamination. It acts as a preservative, preventing the growth of bacteria, parasites, and other microbes that can contaminate the oil. This is especially important in aromatherapy, where essential oils are used for personal and home care products.
Alcohol is an effective preservative because it creates an environment that is inhospitable to microbial growth. Microbes, such as bacteria and parasites, cannot survive in the presence of high concentrations of alcohol. By using alcohol as a preservative, the essential oils can be kept safe and free from contamination.
In addition to its preservative properties, alcohol also helps to properly dissolve the essential oils. Many essential oils are soluble in alcohol, which means they can be easily mixed and dispersed in the diffuser liquid. This is important because it ensures that the essential oils are evenly distributed and can be effectively released into the air during diffusion.
The type and concentration of alcohol used are important factors in eliminating microbial contamination. For effective preservation, high-concentration ethanol is typically recommended. This includes grain alcohol that is 190 proof (95% ethanol) or, at a minimum, 151 proof (75-75.5% ethanol). Using alcohol with a lower concentration may not properly dissolve the essential oils and may be less effective at inhibiting microbial growth.
Overall, the use of alcohol in diffuser oil serves an important purpose in eliminating microbial contamination. It helps to preserve the quality and safety of the essential oils, ensuring that they can be effectively and safely used for aromatherapy and other personal care applications.

It acts as a preservative
Alcohol is used in diffuser oil to act as a preservative and eliminate microbial contamination. Alcohol is a key ingredient in reed diffuser liquids, which are often made at home. To make a reed diffuser liquid, a binding agent is required to help the oil bind with the water, as oil and water do not mix. Alcohol is used for this purpose, with ethanol or isopropyl alcohol being the most common types.
Alcohol is an effective preservative in diffuser oil as it can eliminate microbial contamination. Microbes are less likely to grow in a mixture that contains alcohol. For example, if tap water is used in a diffuser oil mixture, the alcohol added to the water will help to prevent bacterial growth. This is why alcohol is often added to diffuser oils to act as a preservative and extend the shelf life of the product.
The type of alcohol used is important, as not all alcohols are effective preservatives. The alcohol used should contain 95-100% ethanol to properly act as a preservative and solubilize the essential oils. Cheaper alcohols, such as vodka, often contain only 40-50% ethanol and are therefore not suitable for this purpose. Grain alcohol that is 190 proof (95% ethanol) is recommended for effective preservation and solubilization.
In addition to its preservative properties, alcohol also helps to dissolve the essential oils in diffuser oil. Some essential oils can take a long time to dissolve, while others may never fully dissolve. Alcohol helps to speed up the dissolution process and ensure that the oils are properly mixed into the water. This is important for both the effectiveness of the diffuser oil and the safety of the user.
Overall, alcohol plays a crucial role in diffuser oil by acting as a preservative, preventing microbial contamination, and aiding in the dissolution of essential oils. It is an essential ingredient in reed diffuser liquids and helps to ensure the effectiveness and safety of the product.

It helps essential oils dissolve
Essential oils are hydrophobic, meaning they don't mix with water. This is where alcohol comes in—it acts as a binding agent, allowing the oil and water to form a homogeneous solution.
Alcohol and oil are miscible, meaning they can mix and form an even solution. This is because both substances are non-polar, so they can interact and blend well. By mixing essential oil and alcohol, you can use less essential oil in your diffuser liquid while still obtaining a suitable volume for your reed diffuser bottle.
To make diffuser liquid, you should mix the essential oil with alcohol first, before adding water. This helps to prevent separation between the three ingredients. The ideal type of alcohol for this purpose is ethanol, with a concentration of 95-100%. This concentration is important because it ensures the essential oils dissolve properly. Vodka can also be used, but it should not be diluted with water, as vodka is already 40% water.
It's worth noting that some essential oils will dissolve more readily than others. For example, light and volatile citrus oils will dissolve quickly, while thicker, more resinous oils like myrrh may never fully dissolve in alcohol. In these cases, Special Denatured Alcohol (SDA or perfumer's alcohol) can be used, but it may not be as accessible to home users.

It can be used to clean empty essential oil bottles
One of the many uses of alcohol is to clean empty essential oil bottles. This is a great way to reuse old bottles. The process is simple: use 95% alcohol to clean the bottles, then rinse them with warm soapy water or put them in the dishwasher. This method ensures that the bottles are thoroughly cleaned and sanitised, ready for refilling and reuse.
Alcohol is an excellent cleaning agent and solvent, especially when dealing with oily substances. Its effectiveness is due to its ability to dissolve oils and other organic compounds. In the case of essential oils, alcohol can effectively break down and remove any residual oil left in the bottles.
It is important to note that not all alcohols are created equal when it comes to cleaning essential oil bottles. The type and concentration of alcohol are crucial. For effective cleaning and solubilizing, the alcohol used should contain 95–100% ethanol. Common options include grain alcohol (such as Everclear®), vodka, or isopropyl alcohol.
When using vodka or isopropyl alcohol, it is essential to ensure that the concentration is at least 95%. Lower concentrations, such as those found in cheap vodka (typically 80 or 100 proof, or 40–50% ethanol), may not properly solubilise the essential oils, leaving behind a greasy residue.
After cleaning the bottles with alcohol, rinsing them with warm soapy water or placing them in the dishwasher ensures that any alcohol or oil residue is removed, leaving the bottles clean and ready for reuse.
