Mixing fragrance oil with water is a unique form of alchemy that may seem magical and elusive, but it is possible. Water is a natural solvent that liquefies many substances, but not all raw materials dissolve in water, including fragrance oils. To mix fragrance oil with water, one can use an emulsifier like polysorbate 20, cetyl alcohol, sodium laureth, or sulfate. Alcohol is a preferred choice as a solvent because of its composition of polar molecules. It is important to note that oil and water are not miscible, and the addition of water to perfume may cause contamination issues. However, some people add water to perfume to detract from the harshness of the alcohol or as a cost-saving measure.

What You'll Learn
Using an emulsifier like polysorbate 20
Polysorbate 20 is a non-toxic, nonionic surfactant/emulsifier that is often used to mix fragrance oil with water. It is a water-soluble liquid that acts as a dispersing agent, allowing oil and water to mix without the use of alcohol. This emulsifier helps to blend the oil with other liquids effectively and is commonly used in the cosmetics and pharmaceutical industries.
To mix fragrance oil with water using polysorbate 20, follow these steps:
- Start with a ratio of 1:1. For example, for every ounce of fragrance oil, mix with one ounce of polysorbate 20. It is important to mix these two ingredients thoroughly and allow them to combine completely.
- Once you have a homogeneous mixture of fragrance oil and polysorbate 20, you can introduce distilled water. The amount of water you add will depend on the consistency and fluidity you desire for your final product. For a room spray, for instance, you can use nine parts water to one part polysorbate 20.
- It's important to note that the amount of polysorbate 20 used can affect the scent throw of the fragrance oil. Using too much polysorbate 20 can weaken the fragrance and reduce its throw. Therefore, it may require some experimentation to find the optimal ratio for your specific fragrance oil and desired scent throw.
- If you're using a larger batch size, you can simply scale up the measurements accordingly while maintaining the same ratio. For example, if you want to make a bigger quantity of room spray, you can increase the amount of polysorbate 20 and fragrance oil while keeping the 9:1 ratio of water to polysorbate 20 constant.
Polysorbate 20 is a versatile ingredient that can be used with both essential oils and synthetic fragrances. It is also skin-safe and soothing, making it suitable for use in various cosmetic applications such as lotions, conditioners, shampoos, and body mists.

Adding alcohol
Oil and water don't mix, but oil and alcohol do. When mixing fragrance oil with water, alcohol can be used as a solvent to blend the two together. The specific composition of polar molecules in alcohol, which have both positive and negative aspects, makes it a preferred choice as a solvent. This is because alcohol is less polar than water, so it evaporates more quickly and boils at a lower temperature.
To use this method, you can start by mixing alcohol and water in a separate container. Then, add your fragrance oil to this mixture. The amount of each ingredient will depend on the desired strength of your final fragrance and can be adjusted accordingly. It's important to note that the type of alcohol used is crucial; ethanol or ethyl alcohol, also known as cetyl alcohol, is the most suitable for this purpose. The ethanol should be 190+ proof or 96% concentration.
There are a few things to keep in mind when using alcohol to mix fragrance oil with water. Firstly, while alcohol can help combine the oil and water, it may not create a completely clear solution. Some cloudiness and oil bubbles can still be expected. Secondly, the addition of water to a perfume solution may increase the risk of contamination, which can ruin your fragrance. To minimize this risk, it is recommended to use distilled water, which has been purified through distillation to remove impurities.
Additionally, you can also use an emulsifier like polysorbate 20 to help combine the oil and water. Emulsifiers act as chemical agents that stabilize fragrances by forming physical barriers between the oil and water, preventing them from separating. However, when using an emulsifier, you will also need to add a preservative and an antimicrobial agent to your mixture.

Using distilled water
It is important to note that oil and water do not mix naturally. Oil is lighter than water and will float on the surface. Water is also non-invasive and gentler on the skin than other substances.
If you are mixing fragrance oil with water, it is recommended to use distilled water. This is because distilled water is a very specific type of water and is not found in 99% of perfumes and never in oil-based perfumes.
To mix fragrance oil with distilled water, you will need an emulsifier or dispersant. Emulsifiers are chemical agents that help to stabilize fragrances by blending two ingredients that are considered incompatible, forming physical barriers between them that prevent consolidation. They are attracted to both polar and non-polar compounds and help dissolve fragrance oils. Emulsifiers include grain alcohol (20% of your mix), liquid Castile soap (a few drops), and Solubol (a more advanced emulsifier).
- Choose the right fragrance oil. Popular choices include lavender, lemon, and peppermint.
- Use a carrier oil for skin applications. Carrier oils like coconut or jojoba oil help to dilute the potency of the fragrance oil, making it safe for the skin. A typical ratio is 1 drop of fragrance oil for every 5-10 drops of carrier oil.
- Add the emulsifier. The emulsifier will help the fragrance oil and distilled water mix evenly and create a stable texture.
- Mix the ingredients. The mixing ratio will depend on the desired product. For a room spray, a common ratio is 20% essential oil, 70% alcohol, and 10% distilled water.
- Shake well before each use to ensure the oil remains evenly distributed.

Combining with glycerin or vegetable oil
Combining fragrance oil with water can be challenging due to the chemical differences between the two substances. Oil molecules are non-reactive and do not dissolve in water, leading to separation and a cloudy appearance. However, there are methods and ingredients that can help combine them.
One approach is to use an emulsifier, such as polysorbate 20, cetyl alcohol, sodium laureth, or sulfate. Emulsifiers act as chemical agents that stabilize fragrances by forming physical barriers between the oil and water, preventing them from separating. This results in a water-soluble emulsion, a finely divided mixture of liquids that creates a stable and even texture. However, it is important to note that using an emulsifier may require the addition of a preservative and antimicrobial agent.
Another option is to use alcohol as a solvent. Alcohol, specifically ethanol or ethyl alcohol, has polar molecules that help blend essential oils and water into a homogeneous substance. Its chemical composition allows it to evaporate rapidly and boil at a lower temperature than water. However, some people may prefer to avoid alcohol due to its potential harshness on the skin.
When creating a fragrance, combining fragrance oil with glycerin or vegetable oil can be a useful option. Glycerin, also known as glycerol, is a natural emulsifier that helps stabilize the mixture and promote a longer-lasting scent. It also adds a slight sweetness to the fragrance and can provide additional skin benefits, such as moisturizing properties.
To combine fragrance oil with glycerin or vegetable oil, start by mixing the desired amount of fragrance oil with glycerin in a separate container. Vegetable oil can also be added as a carrier oil, which helps the fragrance adhere to the skin and prolong its duration. The ratio of fragrance oil to glycerin or vegetable oil can be adjusted based on the desired strength and longevity of the scent.
Once the fragrance oil and glycerin (or vegetable oil) are combined, pour the mixture into a dark, sealed container. Shake the container vigorously for several minutes to blend the scents evenly. It is important to use a dark container as light can degrade the quality of the fragrance over time.
Allow the mixture to sit in a cool, dark place for up to two weeks, shaking the container daily to prevent separation and ensure thorough blending. This process allows the fragrance to mature and develop its full aroma. You can also add dried flowers or flower petals to the container for a personalized touch and additional scent infusion.
After the resting period, your customized fragrance oil and glycerin (or vegetable oil) mixture are ready for use. You can apply it to the skin, add it to bathwater, or use it to scent homemade beauty products like creams or lotions. The addition of glycerin or vegetable oil helps the fragrance last longer and provides a more satisfying sensory experience.

Shaking the mixture
Firstly, it is important to understand the role of shaking in the mixing process. Shaking helps to mechanically blend the oil and water, temporarily creating a homogeneous mixture. This is particularly important when using an emulsifier, a chemical agent that stabilizes the mixture by forming physical barriers between the oil and water, preventing them from separating. Shaking ensures that the emulsifier is evenly distributed throughout the mixture, creating a stable emulsion.
The addition of certain ingredients, such as alcohol or emulsifiers like polysorbate 20, cetyl alcohol, or sodium laureth, can also aid in the mixing process. Alcohol, specifically ethanol or ethyl alcohol, acts as a solvent, blending the essential oils and water into a homogeneous substance. Emulsifiers, on the other hand, are attracted to both polar and non-polar compounds, helping to dissolve the oil into the water and preventing the need for shaking before use.
To effectively shake the mixture, follow these steps:
- Combine the fragrance oil, water, and any additional ingredients, such as alcohol or emulsifiers, in a separate container.
- Seal the container tightly to prevent spillage.
- Shake the container vigorously for several minutes. The duration and intensity of shaking may vary depending on the specific ingredients and quantities used.
- Allow the mixture to rest for a period of time, such as the recommended two weeks, during which the mixture should be shaken daily to promote further blending and prevent separation.
It is important to note that even with shaking and the use of emulsifiers or alcohol, the mixture may still experience some degree of separation over time due to the inherent differences between oil and water. However, shaking remains a crucial step in the process of creating a stable and well-blended fragrance mixture.
