Creating Your Own Roll-On Cologne: A Simple Guide

Making roll-on cologne is a fun way to explore new scents and experiment with creating your own fragrances. While making custom formulations can seem daunting, it's actually a simple process that anyone can do at home. In this guide, we will teach you how to make your own roll-on cologne using essential oils and fragrance oils, as well as how to apply it for the best aromatic results.

Choose a blend of essential oils

Choosing a blend of essential oils is a fun way to explore new scents. However, formulating your own custom blends can be challenging. The key to creating a pleasing aroma is understanding how different essential oils blend together.

Essential oils come in a wide range of scent notes, from woodsy and herbal to citrus and floral. To create a harmonious blend, it is important to select oils that complement each other. You can find this information by conducting an internet search or referring to books on essential oils.

When formulating a blend, it is important to consider the volatility of the oils, which refers to their rate of evaporation. Oils are categorised into top notes, middle notes, and base notes. Top notes evaporate the fastest due to their small molecules, while middle notes can last several hours, and base notes, with their large molecules, evaporate the slowest, lasting a full day or more.

A well-rounded blend will typically include a combination of all three notes. As a general guideline, top notes should make up 10%-30% of the blend, middle notes 30%-50%, and base notes 15%-30%. Middle notes are considered the heart of the perfume and should be the focal point, with the other notes chosen to harmonise and complement them.

When creating your own blend, it is recommended to start with a base note and/or a fixative, as these will help your fragrance last longer. Fixatives are materials added to slow down the degradation of more volatile oils, resulting in a longer-lasting scent. Examples of essential oils that can act as fixatives include Amyris, Angelica Root, Peru Balsam, Atlas Cedarwood, and Cistus.

Additionally, it is important to choose essential oils that appeal to your sense of smell. You can experiment with different oils and create unique combinations to find your perfect scent.

Once you have selected your essential oils, you can follow these steps to create your roll-on cologne:

• Combine your chosen essential oils in a small glass bottle, adding one drop of each at a time to achieve your desired scent.
• After creating your blend, place a drop on a piece of paper and smell it at different intervals (such as after an hour and after two hours) to evaluate how the scent develops over time. Make adjustments to your blend as needed.
• Once you are happy with your blend, combine it with a carrier oil such as fractionated coconut oil or jojoba oil. Fill your roller bottle almost to the top, leaving some room for the rollerball.
• Screw on the rollerball and cap, then shake the bottle well to mix the oils.
• Allow the blend to rest for a day or two before use so that the scent can mature and develop.

Understand fragrance notes

Understanding fragrance notes is crucial when creating your own cologne. Fragrance notes are the individual scent layers that, when combined, form a unified and pleasing perfume. They are typically categorised into three types: top notes, heart/middle notes, and base notes. Each note has a specific role in the fragrance's development and longevity, and they work together to create a complex and appealing scent.

Top notes are the initial scents you detect after applying cologne. They are light and fresh, usually consisting of smaller molecules that evaporate quickly, lingering for only the first 5-15 minutes. Common top notes include citrus scents like lemon, orange, and bergamot, as well as light floral scents such as lavender and rose.

Heart notes, or middle notes, emerge as the top notes start to fade. They form the heart of the fragrance, introducing new scents while retaining some of the top notes. These notes are usually full-bodied and complex, lasting several hours and contributing to the overall character and longevity of the scent. Examples of middle notes include aromatic floral oils like jasmine, geranium, and ylang-ylang, as well as spices like cinnamon and cardamom.

Base notes are the foundation of the fragrance. They become more prominent as the top and middle notes dissipate, adding depth and resonance. Base notes are rich, deep, and long-lasting, with a strong aroma that can linger for six hours or more. Popular base notes include vanilla, amber, musk, patchouli, moss, and woody notes such as sandalwood and cedarwood.

When creating your own cologne, it's important to choose notes that complement each other and create a harmonious blend. You can experiment with different combinations of top, middle, and base notes to find your unique scent. Additionally, consider the occasion and time of day when selecting a fragrance, as certain notes may be more suitable for daytime or evening wear.

Understanding fragrance notes gives you the power to create a signature scent that resonates with your style and personality.

Use a carrier oil

When making roll-on cologne, it's important to include a carrier oil to dilute the essential oils. This is because applying undiluted essential oils directly to the skin can cause irritation or sensitivity. Carrier oils are usually odourless and have a long shelf life, so they won't interfere with your chosen scent or go rancid before use.

Fractionated coconut oil is a popular choice as it is clear, odourless, and has a soothing effect on the skin. It also has an excellent shelf life, perhaps the longest of all carrier oils. Jojoba oil is a good alternative, offering similar benefits.

When making your roll-on cologne, simply add your chosen essential oils to a glass bottle using a dropper or pipette, then fill the rest of the bottle with your carrier oil of choice. Be sure to leave a little room at the top for the rollerball, then screw on the lid and shake to combine.

It's worth noting that carrier oils aren't the only way to dilute essential oils. Cyclomethicone, a synthetic liquid silicone, can also be used. It is clear, odourless, and has a long shelf life, making it ideal for homemade perfumes. It also has a non-greasy feel, so it won't leave an oily residue on the skin.

Mix and test the blend

Mixing your own cologne can be a fun way to explore new scents and express your creativity. However, it can also be a daunting task, especially when it comes to blending different oils to create a harmonious and pleasing fragrance. Here are some detailed instructions and tips to guide you through the process of mixing and testing your own unique roll-on cologne blend:

Understanding Fragrance Notes:

Before you begin mixing, it's important to understand the different types of fragrance notes and their roles in creating a well-rounded and long-lasting cologne. Fragrance notes are categorised into three groups: top notes, middle notes, and base notes. Top notes are light and airy, introducing you to the scent. They evaporate the fastest because they contain the smallest molecules. Examples of common top notes include citrus oils like grapefruit, lemon, and orange, as well as mint oils. Middle notes form the heart of your cologne and are usually full-bodied and complex. These notes are the focal point of your blend, with other notes chosen to complement them. Popular middle notes include black pepper, cinnamon, and clove (use these sparingly as they can be skin irritants). Base notes are dense, heavy, and strong, providing support and depth to the overall formulation. Examples of base notes include sandalwood, patchouli, and vanilla.

Choosing Your Essential Oils:

When creating your own cologne blend, it's recommended to choose at least three essential oils, each representing a different fragrance note. This will result in a more complex and well-rounded fragrance. However, feel free to experiment with more aromas to create unique combinations. You can select essential oils based on their scent profiles, such as woody, herbal, citrus, floral, or spicy notes. Additionally, consider the rate of evaporation, or volatility, of the oils. Top notes evaporate quickly, middle notes last several hours, and base notes can linger for a full day or more.

Mixing Your Oils:

Once you've selected your essential oils, it's time to start mixing! Use small glass bottles, such as 5 mL or 15 mL amber glass bottles, to create your blends in small quantities and experiment with different ratios. Add one drop of each aroma oil to your bottle, then continue adding drops until you achieve the desired scent. You can also use blending factors, which indicate the strength of a scent on a scale from 1 to 10, to help guide your mixing process. However, ultimately, you should create a blend that you enjoy and want to wear. Don't forget to take breaks and reset your sense of smell by smelling coffee grounds between different blends.

Testing Your Blend:

After creating your blend, place a drop on a piece of paper or a perfumer's testing strip. Smell the blend right away, and then again after an hour and two hours to see how the scent evolves over time. Make notes on the different scents you perceive, and adjust the ratios of essential oils as needed. This process may require several iterations to perfect your cologne blend.

Using a Carrier Oil:

When creating a roll-on cologne, it's important to use a carrier oil to dilute the essential oils and prevent skin sensitivity or irritation. Carrier oils should have little to no scent so they don't interfere with your fragrance. Fractionated coconut oil and organic jojoba oil are excellent choices as they are clear, odourless, and have a long shelf life. Fill your roller bottle mostly with the carrier oil, leaving room for the rollerball, and then add your blend of essential oils.

Storage and Maturity:

After mixing your cologne, store it in a cool, dark place for around one to two weeks before using it. This allows the essential oils to fuse and mature, resulting in a more blended and developed scent.

Creating your own roll-on cologne can be a fun and rewarding experience. By understanding fragrance notes, choosing complementary essential oils, and carefully mixing and testing your blends, you can design a unique and captivating fragrance that suits your taste and personality.

Apply to pulse points

Applying your roll-on cologne to your pulse points is a great way to make the most of its scent. Pulse points are small areas of the body that emit extra heat due to the proximity of arteries to the skin's surface. This heat helps to strengthen the cologne's fragrance.

Common pulse points for perfume application include the wrists, inside of the elbows, the collarbone, the back of the knees, and behind the ears. Applying cologne to these areas will create a sense of movement in your fragrance as your arms are constantly moving. Additionally, you can try applying cologne to your temples, especially if it contains peppermint, eucalyptus, or lavender oil, as this can help relieve stress.

It is recommended to apply roll-on cologne just after taking a warm bath or shower. This will open up your pores and allow the fragrance to absorb better, making the scent last longer.
