Diluting Fragrance Oils: Using Alcohol For A Better Scent

Alcohol is often used as a diluting agent in perfumes, as it helps to create a sprayable consistency and aids in the dispersion and evaporation of the fragrance on the skin. When making an alcoholic perfume, it is important to choose the right type of alcohol, such as perfumer's alcohol or ethanol, to ensure the safety and effectiveness of the final product. The use of alcohol in perfumes can enhance the fragrance experience by carrying the scent further and creating a cloud of scent around the wearer. However, it is important to dilute fragrance oils properly and allow sufficient time for the ingredients to blend and mature, which can take several weeks or even months.

Using perfumer's alcohol to dilute fragrance oil

Perfumers alcohol is a popular choice for diluting fragrance oils. It is essentially ethyl alcohol that has been denatured, meaning something has been added to it to make it undrinkable. This is done for safety reasons.

Perfumers alcohol is ideal for diluting fragrance oils as it can fully dilute the ingredients, acting as a preservative. It is also necessary for sprayable perfumes. Alcohol lifts the fragrance, carrying it further as it evaporates off the skin.

However, it is important to note that alcohol-based perfumes may not be suitable for certain applications, such as candles, creams, detergents, or oils. Additionally, alcohol can be drying to the skin, so it may not be the best choice for those with dry skin.

When diluting fragrance oils with perfumers alcohol, it is important to use a scale rather than drops to ensure an accurate and repeatable formula. The general guideline is to dilute most materials by 10%, but stronger materials like Ethyl Vanillin may only need 1%.

It is also worth mentioning that perfumers alcohol is not suitable for natural perfumery, as it is petrochemical-derived. For a more natural option, fractionated coconut oil can be used as a carrier oil. It is clear, odourless, and has an indefinite shelf life. However, oil-based perfumes have a shorter range and may not be suitable for those who prefer a stronger, more noticeable scent.

Vodka as a diluting agent

Vodka is a popular choice as a diluting agent for fragrance oils. It is one of the two key components of a basic perfume, the other being oil. Vodka is a high-proof alcohol that can be used to dilute fragrance oils and create a sprayable perfume.

When creating a perfume, it is important to add your base, middle, and top notes in that order, following the basic 20-50-30 percent ratio. You can also add a few drops of a bridge note if desired. Once you have added your notes, fill up your bottle with vodka as the diluting agent, shake it well, and let it sit for at least 48 hours. The longer you wait, the stronger the scent will be, with the maximum time suggested being six weeks.

After the waiting period, you can add two tablespoons of water, pour the mixture through a coffee filter, and return it to the bottle. It is important to keep detailed records and clearly label your creations when experimenting with perfume-making. Even using two fewer drops of one type of oil can significantly change the aroma.

Vodka is an effective diluting agent because, as an alcohol, it carries the scent further. As the alcohol evaporates, it takes some of the fragrance with it, radiating the scent outward. This is different from oil carriers, which keep the scent closer to the skin as the oil soaks into the pores. With vodka and other alcohol carriers, a little goes a long way, but what is gained in projection is lost in longevity.

The role of a carrier in fragrance oil

A carrier is a base ingredient used to enhance the evaporation or diffusion of a fragrance material or the fragrance blend. It is fundamental when preparing any perfume. The role of a carrier in fragrance oils is threefold:

Protect the wearer

Firstly, many essential oils and fragrance ingredients can be harmful when applied directly to the skin. They can be caustic, contain allergens, or cause rashes. Diluting the oils in a carrier can reduce these problems.

Lift and carry the scent

The carrier you use will influence how long a perfume lasts and how far the scent reaches. Alcohol, for example, will carry the scent further as it evaporates, whereas oil will keep the scent closer to the skin as it soaks into the pores.

Dilute the fragrance

Fragrance ingredients are often too pungent to wear without a carrier. A carrier tones down the fragrance, creating a subtle enhancement to our general aroma.

When selecting a carrier, you can choose between natural and chemical options. Natural carrier oils, such as jojoba, almond, and coconut oil, dilute the perfume while also offering benefits to the skin. Chemical carrier oils, on the other hand, are often derived from petroleum or synthetic sources and can compromise the integrity of perfumes.

How long to let diluted fragrance oil sit

When making perfume oil at home, it is important to let the mixture of alcohol and fragrance oil sit for a while before using it. This allows the ingredients to combine properly and creates a well-balanced perfume.

After adding the fragrance oil to the alcohol, the mixture should be left undisturbed for 24 hours. During this time, the alcohol and fragrance oil will mix thoroughly, creating the base of your perfume. This step is crucial in ensuring that your perfume has the desired scent and strength.

While waiting for the mixture to rest, you can prepare the water-glycerin mixture, which will add moisture to your perfume and make the aroma last longer on your skin. After the 24-hour waiting period, simply combine the two mixtures, shake the bottle gently, and your perfume is almost ready!

It is recommended to test the spray strength by applying a small amount to your skin and adjusting the perfume oil or water accordingly. Once you are happy with the intensity and fragrance, it is best to let the perfume sit for another 5 to 6 weeks in a cold, dark place before using it. This waiting period ensures that your perfume reaches its optimum benefits, and you can fully enjoy its scent and longevity.

The dangers of adding water to perfume

Perfume is a delicate mixture of fragrance and carrier. The carrier is a base material that "carries" the scent. It protects the wearer, lifts and carries the scent, and dilutes the fragrance. While it is possible to use water as a carrier, it is not recommended due to the following dangers:

Firstly, water can cause cloudiness in the perfume. This is because water and oil do not mix well, and adding water can cause the oil-based fragrance to separate and float to the top, creating an unattractive and uneven mixture.

Secondly, water can affect the scent of the perfume. Water has a high vapour pressure and can increase the rate of evaporation of the fragrance, causing the scent to be less noticeable and not last as long. This is especially true if too much water is added.

Thirdly, water can cause solubility issues with the fragrance. Most perfumery materials do not dissolve in water, and adding water can create an uneven mixture where the fragrance is not fully incorporated.

Additionally, water can affect the skin. While some people add water to reduce the drying effect of alcohol on the skin, it is not necessary, and water can actually increase the chances of skin irritation or allergic reactions.

Lastly, water can be difficult to work with in perfumery. It does not aid in the evaporation of the fragrance, making it harder to evaluate the odour profile of the materials. It can also be challenging to measure out small amounts of water accurately, leading to an inconsistent product.

In conclusion, while it may be tempting to add water to dilute a perfume, it is not recommended due to the potential dangers outlined above. It is best to leave the dilution process to professionals who have the knowledge and experience to do so safely and effectively.
