What You'll Learn
151-proof alcohol is a good alternative if 190-proof alcohol is unavailable
When making an essential oil air freshener, the type and strength of the alcohol used are important considerations. While 190-proof alcohol is recommended for effectively solubilizing essential oils, 151-proof alcohol can be a good alternative if the former is unavailable.
Firstly, it is important to understand the role of alcohol in an essential oil air freshener. Alcohol acts as a preservative and assists in evaporation, preventing surfaces from becoming wet. Additionally, the antimicrobial properties of high-strength alcohol help prevent microbial growth and extend the shelf life of the product.
For effective solubilization, the alcohol used should ideally contain 95-100% ethanol. 190-proof grain alcohol, such as Everclear, meets this criterion and is therefore recommended for making essential oil air fresheners. However, in the event that 190-proof alcohol is not available, 151-proof alcohol can be used as a substitute.
While 151-proof alcohol may not solubilize essential oils as easily as 190-proof alcohol, it still meets the minimum requirement of 60% ethanol content for a water-based spray. This lower-proof alcohol can effectively kill microbes on surfaces, even if it may not completely dissolve thick essential oils. Additionally, 151-proof alcohol can still provide an antimicrobial effect, helping to prevent mold growth and prolong the preservation of the air freshener.
When using 151-proof alcohol, it is important to follow similar guidelines as with higher-proof alcohols. This includes proper labeling, especially regarding flammability, and avoiding spraying near open flames or heat sources. Additionally, as with any essential oil air freshener, it is recommended to make small batches that last for a limited period, such as 1-2 months, rather than keeping the product indefinitely.

It is a minimum requirement for solubilization purposes
When making an air freshener with essential oils, it is important to use a high-proof alcohol, such as 151-proof vodka, for solubilization purposes. This is because essential oils are soluble in oils but not in water, so a high-proof alcohol is needed to dissolve the essential oils and create a stable product that won't separate.
The use of 151-proof alcohol is a minimum requirement for solubilization purposes. This means that it is the lowest concentration of alcohol that will effectively dissolve the essential oils. While it may not solubilize the oils as easily as 190-proof grain alcohol (95% ethanol), it is a more readily available option that can still be effective.
The high alcohol content in 151-proof alcohol helps to preserve the air freshener by preventing microbial growth. This is important because essential oils can be susceptible to microbial contamination, which can reduce their effectiveness and shelf life. By using a high-proof alcohol, you can ensure that your air freshener remains stable and effective for a longer period of time.
Additionally, the alcohol content helps to distribute the essential oils in the water, creating a consistent and well-blended product. This ensures that the air freshener sprays evenly and effectively, providing a pleasant and consistent fragrance experience.
It is important to note that when using 151-proof alcohol, you may need to adjust the ratio of alcohol to essential oils to ensure complete solubilization. This may involve using a higher percentage of alcohol or experimenting with different types of essential oils to find the optimal combination.
In summary, using 151-proof alcohol is a minimum requirement for solubilization purposes when creating an essential oil air freshener. It helps to dissolve the essential oils, preserve the product, and ensure even distribution of the fragrance. By understanding the role of high-proof alcohol, you can create effective and stable air fresheners with your desired essential oil blends.

It can prevent microbial growth in your spray
When making an essential oil air freshener, it is important to use high-proof alcohol to prevent microbial growth in your spray. While 190-proof grain alcohol is the best option, 151-proof alcohol is a suitable alternative.
Essential oils are soluble in oils but not in water. They are, however, partially soluble in alcohol. Therefore, when making an essential oil air freshener, the essential oils must first be dissolved in alcohol before adding water. The alcohol used needs to contain 95-100% ethanol for effective solubilizing purposes. While 190-proof grain alcohol meets this criterion, 151-proof alcohol only contains 75-75.5% ethanol. However, 151-proof alcohol can still be used to prevent microbial growth in your spray.
The higher the strength/proof of the alcohol, the longer it will preserve your air freshener for. Therefore, 151-proof alcohol will preserve your air freshener for longer than lower-strength alcohol. Additionally, the percentage of ethanol in the total spray formula should be between 20-30%. A higher percentage of ethanol will further prevent microbial growth in your spray.
It is important to note that while 151-proof alcohol can prevent microbial growth in your spray, it may not solubilize essential oils as easily as 190-proof grain alcohol. Therefore, when using 151-proof alcohol, it is recommended to follow certain recipes to ensure effective solubilization. One recipe suggests using 2 tablespoons of 151-proof alcohol, letting the desired drops of essential oils sit for 5 minutes, shaking well, and then adding 6 tablespoons of filtered water.
By using 151-proof alcohol and following recommended recipes, you can effectively prevent microbial growth in your essential oil air freshener spray.

It can help distribute essential oils in water
When making an essential oil air freshener, 151-proof alcohol can help distribute essential oils in water. This is because essential oils are soluble in oils but not in water, and they are only partially soluble in alcohol. To dissolve an oil, it needs to mix into a substance so completely that it won't separate out. In this case, the essential oils are dissolved in alcohol first, and then topped off with water.
The higher the proof of the alcohol, the better it will solubilize the essential oils. For effective solubilization, the alcohol used needs to contain 95-100% ethanol. 151-proof alcohol contains 75-75.5% ethanol, which may not solubilize essential oils as easily as 190-proof alcohol (95% ethanol). However, 151-proof alcohol is still preferable to lower-proof alcohols, which will have even less solubilizing power.
The percentage of ethanol that is part of the total spray formula should be a minimum of 20-30%. This is because, in addition to solubilizing the essential oils, the alcohol also acts as a preservative to prevent microbial growth in the spray. A higher percentage of ethanol will therefore increase the shelf life of the product.
When making an essential oil air freshener with 151-proof alcohol, it is recommended to add the essential oils to the alcohol first, swirl to combine, and let sit for a few minutes. Then, distilled water can be added to the mixture.

It can preserve the air freshener
The use of 151-proof alcohol in an essential oil air freshener can help preserve the product. While 190-proof grain alcohol is recommended for effective solubilization, 151-proof alcohol can be used as a substitute. This lower-proof alcohol may not solubilize essential oils as easily, but it can still be effective in preventing microbial growth.
The alcohol content in the air freshener formulation plays a crucial role in preservation. A minimum alcohol content of 20% is required for the product to act as a preservative. Specifically, for a water-based spray, the alcohol used should have a minimum of 60% ethanol content, which equates to at least 120-proof grain alcohol. This level of alcohol helps prevent microbial growth in the spray rather than simply killing microbes on surfaces.
The inclusion of 151-proof alcohol in an essential oil air freshener can, therefore, contribute to its preservation by inhibiting microbial growth. This preservation property is due to the antimicrobial effect of the alcohol, which helps prevent the formation of mold.
It is worth noting that while 151-proof alcohol can be effective for preservation, it may not be the best choice for solubilization. Depending on the viscosity and specific gravity of the essential oils used, even 95% ethanol may not completely dissolve thick essential oils. In such cases, Special Denatured Alcohol (SDA) or perfumer's alcohol can be considered, although these options may not be readily available to home users.
To summarize, 151-proof alcohol can preserve an essential oil air freshener by preventing microbial growth and inhibiting mold formation. However, for optimal solubilization of essential oils, higher-proof alcohols or alternative solvents like SDA may be required.
