Perfumer's alcohol is a popular choice for creating room sprays, but it is considered a hazardous substance and requires careful handling. It is highly flammable and typically used in concentrations of 5-10% for room sprays. When combined with fragrance oils, it provides a clear, cloudless solution that effectively carries and disperses the fragrance. The process of creating a room spray with perfumer's alcohol involves measuring and mixing the alcohol with the desired fragrance oil, often with a ratio of 80:20 or 90:10, and allowing the mixture to sit for 24 to 48 hours before use. It's important to note that perfumer's alcohol should not be sprayed directly onto fabrics or surfaces as it may cause staining or slipperiness. Additionally, it should be stored in a safe place, away from children and pets.

What You'll Learn
Perfumers alcohol is a hazardous base
Perfumer's alcohol is a hazardous base. It is highly flammable, with a flashpoint of 15°C and a boiling point of 79°C. It is important to take this into consideration when creating your own room spray, and to include appropriate pictograms and precautionary phrases on your CLP (Classification, Labelling and Packaging).
Perfumer's alcohol is not suitable for creating car diffusers due to its flammability. It is also not suitable for sale in the UK or Europe if it contains Monopropylene glycol and Isopropyl myristate, and your product will not be cleared for retail. However, it is perfect for creating room sprays as it is a strong base that evaporates quickly, leaving behind the scent of your fragrance oil.
Perfumer's alcohol is a great solvent for fragrance oils, and it is what most commercial perfumes are made with. It is a special formulation that allows the simple addition and blending of essential oils and fragrances to produce crystal clear solutions. It is also used in the production of diffuser oils. The blended solutions remain clear and free from cloudiness.
When creating your own room spray, it is important to first weigh your fragrance oil and then add your perfumer's alcohol. Different oils have different densities, so measurements must be made by weight and not by volume. You can then add a small amount of distilled water and an emulsifier or cosolvent, cap and shake. It is recommended to let the mixture sit for two days before first use.
Perfumer's alcohol is a great base for creating room sprays as it is stronger than regular alcohol and has less of a chemical odour. It also acts as a preservative and fully dilutes your ingredients.

How to measure ingredients
To make a room spray with perfumer's alcohol, you will need perfumer's alcohol, fragrance oil, a measuring jug, a 100ml spray bottle, and a screw-cap pump lid.
Perfumer's alcohol is less dense than water, so you will need to measure by weight, not volume. Measure 80ml of perfumer's alcohol and pour it into your measuring jug, then pour it into the spray bottle. Next, measure 20ml of your chosen fragrance oil and add this to the bottle.
If you prefer a stronger scent, you can increase the percentage of fragrance oil. For example, you could use 10g of fragrance oil and 90g of perfumer's alcohol. Alternatively, you could use a 7% fragrance oil, 83% ethanol, and 10% glycerin combination.
Some recipes suggest adding distilled water and an emulsifier or cosolvent, such as monopropylene glycol, to help solubilise the fragrance oil in the alcohol. If you are using distilled water, add half the water to the bottle first, shake, then add the remainder of the water and shake again.
It is important to note that perfumer's alcohol is highly flammable, so take the necessary precautions when handling and storing it.

The importance of shaking
Shaking is an important step in the process of making a room spray with perfumer's alcohol. While it may seem counterintuitive, shaking the mixture can help to combine the ingredients and ensure they are properly distributed. Here are a few reasons why shaking is crucial:
Combining Ingredients
One of the primary purposes of shaking is to combine the fragrance oil and perfumer's alcohol thoroughly. Perfumer's alcohol is a combination of ethanol (denatured) alcohol, isopropyl myristate, and monopropylene glycol. The denatured alcohol is the main carrier for the fragrances, and the monopropylene glycol acts as a cosolvent, helping the fragrance oils to mix with the alcohol. Shaking the mixture vigorously ensures that these components are evenly distributed, resulting in a consistent and effective product.
Preventing Separation
The fragrance oils and alcohol can separate over time, especially if the room spray is not used frequently. Shaking the mixture helps to redistribute the oils throughout the alcohol, preventing separation and ensuring that each spray delivers a consistent fragrance. This is particularly important when creating a strong-scented room spray, as an uneven distribution of oils can lead to an inconsistent fragrance experience.
Emulsification
In some cases, room spray mixtures may require the addition of a small amount of distilled water and an emulsifier or cosolvent. Shaking the mixture after adding water helps to emulsify the solution, ensuring that the water and alcohol blend evenly. Without proper shaking, the water and alcohol may separate, leading to a less effective and aesthetically pleasing product.
Enhancing Fragrance Release
Shaking the room spray can also help to release the fragrance more effectively. The act of shaking creates a fine mist of the solution, which can better disperse the fragrance into the air when sprayed. This results in a more noticeable and impactful scent when the room spray is used.
Safety Considerations
While shaking is important, it is crucial to follow safety guidelines when working with perfumer's alcohol. Perfumer's alcohol is highly flammable, with a flashpoint of 15°C and a boiling point of 79°C. Always take the necessary precautions, such as proper ventilation and avoiding open flames during the mixing process. Additionally, be cautious when shaking, as excessive or aggressive shaking can lead to spills or leaks, which can be hazardous due to the flammable nature of the alcohol.

Using distilled water and an emulsifier
Perfumer's alcohol is a great option for making natural room sprays. It is a clear, unscented alcohol that produces excellent air fresheners. It is highly flammable, so it is important to take that into consideration when creating your room spray.
To make a room spray with perfumer's alcohol and distilled water, you will need:
- Perfumer's alcohol
- Distilled water
- Fragrance oil
- Emulsifier (such as polysorbate)
First, weigh your fragrance oil and perfumer's alcohol. The general rule for concentrations is 5-20% fragrance oil for perfumer's alcohol. You can also add a co-solvent like monopropylene glycol to help control the evaporation of the alcohol. Once you have measured your fragrance oil and alcohol, cap and shake well.
Next, you will add the distilled water. Distilled water is recommended over tap water as it is free from sediments. The amount of distilled water you add will depend on the concentration of your fragrance oil and alcohol mixture. A common ratio is equal parts alcohol and water, but you may need to adjust this depending on the desired strength of your room spray. Add half of the water, cap, and shake well. Then add the remainder of the water and shake again.
Finally, you will add the emulsifier. Emulsifiers help to prevent the separation of the oil and alcohol mixture. Common emulsifiers include polysorbate or products like Augeo. Again, the amount of emulsifier will depend on the concentration of your mixture. Add the emulsifier, cap, and shake well.
It is recommended to let the room spray sit for 48 hours before use to allow the scent to develop fully. You should also shake the spray well before each use to ensure the ingredients are well combined.

Allowing the mixture to sit
After combining the fragrance oil and perfumer's alcohol, it is recommended to let the mixture sit for a specific duration. The suggested time can vary, with some sources advising a minimum of five minutes between each step of adding and shaking the ingredients. Others suggest a longer period of 24 to 48 hours for the final sitting phase, ensuring the fragrance and alcohol blend harmoniously.
During this resting phase, the mixture undergoes a process of optimal blending. The perfumer's alcohol, composed primarily of ethanol, acts as a carrier for the fragrance. The alcohol's high evaporation rate allows it to swiftly dissipate, effectively carrying the fragrance with it and diffusing the scent into the surrounding environment.
Additionally, the isopropyl myristate commonly found in perfumer's alcohol enhances the absorption speed of the formula. While this is not a critical factor for room sprays, it contributes to the overall performance of the spray by aiding in the swift dispersal of the fragrance.
The sitting period also allows the monopropylene glycol, another common ingredient in perfumer's alcohol, to function as a cosolvent. This cosolvent plays a crucial role in solubilizing the fragrance oils within the alcohol. As a result, the potential need for additional emulsifiers or polysorbates is eliminated, simplifying the formulation.
In summary, allowing the mixture to sit is a crucial step that ensures the fragrance oil and perfumer's alcohol blend effectively. This resting period optimizes the evaporation and absorption properties of the perfumer's alcohol, enhancing the overall performance of the room spray.
