Fragrance oils and essential oils are both commonly used to scent soap, but they have very different properties. Fragrance oils are synthetically produced in a laboratory, while essential oils are natural extracts of herbs, flowers, and plants. The choice between the two depends on the desired scent, the soap-making process, and personal preference. Essential oils are highly concentrated and offer therapeutic benefits, but they can be expensive and less stable to work with. Fragrance oils, on the other hand, are more sustainable, cost-effective, and long-lasting, but they may cause discolouration and are not natural, which may limit their market appeal.

What You'll Learn
Pros and cons of both
When it comes to making soap, there are several options for adding fragrance, including essential oils and fragrance oils. Both have their pros and cons, and it is also possible to use a combination of both.
Pros of using essential oils in soap making
Essential oils are natural extracts of herbs, flowers, plants and trees. They are highly concentrated and aromatic, and can be used to create a specific or combined fragrance. They are also associated with health benefits, particularly for the skin, such as antibacterial or antimicrobial properties, pain and inflammation relief, and acne treatment. They are also vegan-friendly and can be sourced from organically grown herbs, trees and flowers.
Cons of using essential oils in soap making
Not all plants produce essential oils, so there are fewer options for fragrance. For example, you won't find strawberry or vanilla essential oils. They can also be more expensive, as they often require large quantities of plant material to produce. The scent may not last as long or be as intense as fragrance oils, and some essential oils may fade in cold-process soap.
Pros of using fragrance oils in soap making
Fragrance oils are synthetically produced and can be created using natural ingredients, as well as artificial aroma chemicals and other materials. They can be carefully formulated to smell like something in nature, or to convey an abstract concept or feeling. There are endless possibilities for aromas, and they are more sustainable and cost-effective than essential oils. They are also long-lasting and potent.
Cons of using fragrance oils in soap making
Fragrance oils are not natural, which may limit their market appeal. They can also cause discolouration in soap, and some may accelerate trace or cause soap batter to seize.

Essential oils: natural vs fragrance oils: synthetic
When it comes to making soap, fragrance is an important consideration. There are two main categories of ingredients used to scent soap: essential oils and fragrance oils.
Essential Oils: Natural
Essential oils are natural extracts of herbs, flowers, plants, and trees. They are highly concentrated oils and often require large amounts of plant material to produce. The benefit of using essential oils in soap is that you know exactly what ingredients are in the final product. They are also associated with reputed health benefits, especially for the skin. Essential oils are natural products and are therefore vegan-friendly.
However, not everything in nature produces an essential oil, so there are fewer options to choose from. They are also not as sustainable as you might think, as large quantities of plant matter are required to create each drop. They are also more expensive than fragrance oils.
Fragrance Oils: Synthetic
Fragrance oils are synthetically produced in a laboratory and can have numerous different ingredients. They are created with a mix of aroma chemicals and natural ingredients like essential oils, extracts, and resins. Just one fragrance oil can be made up of 40-80 materials. Fragrance oils are more sustainable than essential oils as they do not require vast quantities of plant materials to produce. They are also cost-effective and available in a wide range of pre-mixed fragrances.
However, fragrance oils are not natural, which may limit their market appeal. They can also cause discolouration of the soap.

Cost and availability
The cost and availability of essential oils and fragrance oils vary. Essential oils are generally more expensive than fragrance oils due to the large amount of plant material required to produce them. For example, it takes a ton of rose petals to create just one pound of rose oil. The cost of essential oils also depends on the season and crop yields of any given year. For instance, lavender oil, which is one of the most popular essential oils for soap making, ranges from $50 to $80 per pound. Other essential oils, such as lemon and cedarwood, are more affordable, ranging from $30 to $100 per pound.
Some essential oils, like cocoa absolute, are extremely expensive and may not be worth using due to their high cost. Similarly, creating blends with notes of vanilla, almond, and coffee using essential oils, absolutes, and CO2 extracts is not cost-effective, and you will need to charge a premium for these scents.
Fragrance oils, on the other hand, are often chosen for their affordability. They are synthetic products made with a mix of aroma chemicals and natural ingredients like essential oils, extracts, and resins. As a result, there are nearly endless possibilities for aromas, and they can be carefully formulated to smell like something in nature or convey an abstract concept or feeling.
In terms of availability, essential oils can be found at most soap-making suppliers, as well as essential oil distillers and suppliers. However, not every scent occurs in nature, so if you want to create a soap with a specific scent, you may need to use a fragrance oil. Fragrance oils are available in a wide variety of scents, including food-related aromas like apple cider, raspberry, and chocolate, which are popular for soap making.

Discoloration
Essential oils are less likely to cause discoloration than fragrance oils, but it can still happen. For example, folded orange essential oil can give soap a light yellow to peach hue, while dark patchouli essential oil can lend a yellow or pale tan color to cold process soap. A good rule of thumb is that if an essential oil is darker than a pale to medium yellow, you can expect some degree of discoloration. Additionally, certain essential oils, such as citrus oils, tend to fade in cold process soap, so it is recommended to stick with herbs and florals for a longer-lasting scent.
Fragrance oils, on the other hand, are more prone to causing discoloration. Vanilla fragrance oil, in particular, is known to turn soap a dark brown color. This discoloration can develop over time, with the soap becoming darker as it ages. Other fragrance oils, such as Espresso Fragrance Oil, can also cause discoloration, and it is important to read the descriptions before use to understand their potential impact on the color of the soap.
To prevent or mitigate discoloration, there are a few techniques that can be employed. One method is to use a Vanilla Color Stabilizer, which is effective for melt-and-pour soap but may not work consistently for cold process soap. Another approach is to use titanium dioxide, which can lighten tan or light brown discoloration caused by fragrances with low vanilla content. However, it can be tricky to determine the exact amount of titanium dioxide needed, and using too much can result in glycerin rivers.
In conclusion, while discoloration is a common issue in soap-making, it can be managed by understanding the properties of different oils and using appropriate techniques to prevent or minimize color changes. Both essential oils and fragrance oils have their pros and cons in terms of discoloration, and soap-makers can experiment with different oils and techniques to achieve the desired results.

Health benefits
Essential oils are highly concentrated liquids that contain aroma compounds from plants. They are 100% natural and are made from plant extracts, such as flowers, herbs, or roots. The extraction processes, steam distillation or cold extraction, are what create these natural essential oils.
The health benefits of essential oils are vast. Essential oils are generally safe to use on the skin and can help maintain healthy skin from head to toe. They can be used to help treat sensitive skin and can be chosen based on each person's health and skincare needs. For example, tea tree oil has been recognised for its antibacterial, antifungal, and antiseptic qualities, making it an effective acne-fighting agent. It also has anti-inflammatory properties that work to calm excess inflammation. Similarly, lavender essential oil is calming, reduces anxiety, and promotes burn healing.
Essential oils can also be used to help with respiratory issues. Eucalyptus oil, for instance, has been used as a respiratory remedy for centuries and is known for its antimicrobial properties.
Rose essential oil is another example of an essential oil with health benefits. It has been found to help reduce anxiety associated with labor and delivery and has strong antibacterial properties.
Fragrance oils, on the other hand, are made with a mixture of synthetic and natural ingredients. They are created with aroma chemicals, natural ingredients, and other synthetic compounds. While they do not have the same health benefits as essential oils, they are more diverse in terms of the scents they can offer, as they are not limited to natural scents. They are also typically cheaper than essential oils and can be stronger and longer-lasting in soap.
It is important to note that while essential oils have purported health benefits, there is a lack of scientific evidence to support these claims directly. The Food and Drug Administration (FDA) in the United States qualifies essential oils as either drugs or cosmetics, and it is important to purchase quality, pure essential oils from a trusted source.
