Fragrance oils and essential oils are two very different things, despite sounding similar and coming in similar packaging. Fragrance oils are synthetically made in a lab, whereas essential oils are made from natural materials. Essential oils are highly concentrated and need to be diluted before application, whereas fragrance oils are ready to be applied straight from the bottle. Essential oils are well-known for their aromatic properties and therapeutic benefits, while fragrance oils are commonly used in perfumes, colognes and personal care products.

What You'll Learn
Natural vs synthetic
Essential oils are natural. They are extracted from herbs, flowers, and plants, most often through steam distillation. This involves heating the components until a gas is released, then condensing the gas back into a liquid. Essential oils are highly concentrated and potent, and should be used with caution. They are often used in aromatherapy and meditation for their aromatic properties and potential therapeutic benefits. They are well-known for their calming and invigorating effects on the senses, and have been used for centuries.
Fragrance oils, on the other hand, are synthetic. They are created in a lab with a mix of aroma chemicals and natural ingredients like essential oils, extracts, and resins. They are designed to imitate a natural scent and can be made up of 40-80 different materials. Fragrance oils are commonly used in perfumes, colognes, and personal care products, and can be safely used in crafts or as at-home scents. They are also longer-lasting than essential oils due to their chemical composition.
While essential oils are potent and need to be diluted before application, fragrances are full of chemical compounds that can be applied directly. However, some fragrance oils contain undisclosed chemicals that can be inhaled and absorbed through the skin, potentially leading to health issues. Phthalates, for example, are chemical compounds used to give plastics more flexibility and are frequently found in fragrances. These have been linked to health concerns such as cancer and obesity.
It is important to note that not everything in nature produces an essential oil, so there are fewer options available compared to fragrance oils. Additionally, some essential oils are not suitable for certain applications, such as citrus oils which fade in cold-process soap, or cinnamon and clove oils which cannot be used in leave-on products.

Extraction methods
Essential oils are natural extracts derived from various parts of plants, including leaves, flowers, stems, roots, seeds, fruits, bark, wood, and resin. They are usually obtained through methods like steam distillation, cold pressing, or solvent extraction. Steam distillation involves using steam to separate the oil and water-based compounds from the plant material. Cold pressing, also known as expression, is a mechanical process that extracts oil from the plant material without the use of heat. Solvent extraction uses a solvent, such as water, alcohol, hexane, or acetone, to dissolve and separate the desired compounds from the plant material.
Essential oils are highly volatile, meaning they have a low boiling point and evaporate quickly when exposed to heat. This makes them more challenging to work with, especially in candle-making, as the scent may not last as long as fragrance oils. However, their natural ingredients and therapeutic properties make them a popular choice for aromatherapy and meditation practices.
Fragrance oils, on the other hand, are synthetic or natural oils manufactured in a laboratory. Synthetic fragrance oils are created by combining various chemical ingredients to replicate specific scents. They can contain up to 80 chemical components and are designed to provide consistent and long-lasting aromas. Natural fragrance oils, on the other hand, are made by isolating naturally derived fragrance components from complex scents, such as limonene from lemons or geraniol from roses.
The extraction method for fragrance oils involves the use of chemical compounds and laboratory techniques to create the desired scent profile. While the specific processes may vary, the goal is to produce a stable and consistent fragrance that can be used in a wide range of products, from perfumes and cosmetics to candles and soaps.

Testing standards
Fragrance oils, on the other hand, are synthetically manufactured in labs and do not require such rigorous testing. The FDA defines "fragrances" as a combination of chemicals that give each perfume or cologne its distinct scent. Fragrance oils are designed to smell pleasant and are used in perfumes, colognes, and personal care products. However, they do not offer the same therapeutic benefits as essential oils. While fragrance oils are safe for external use, they should not be ingested or applied undiluted to the skin. Some fragrance oils may contain potentially harmful ingredients, such as phthalates, which have been linked to health concerns. Therefore, it is important to carefully research and patch test any fragrance oil before use.

Longevity and potency
Fragrance oils are synthetically manufactured in a lab to imitate a natural scent, whereas essential oils are natural and highly potent. They are extracted from aromatic plant parts, including roots, herbs, or flowers, to capture their beneficial properties, scents, and flavours. Essential oils are 100% oil and are "neat", meaning they are not diluted, mixed, or processed, and do not have any additives.
The average shelf life of a fragrance oil is anywhere from six to twelve months, depending on its composition. They can last longer if stored properly, in a cool, dark place. Fragrance oils are best used in crafts or at-home scents. Essential oils, on the other hand, have been used for centuries and are well-known for their aromatic properties. They are commonly used in aromatherapy and meditation.
Essential oils are highly concentrated and potent, and need to be diluted before application. They should be used with caution, especially on the skin, as some can have a warming effect, while others can be cooling. Despite their potency, essential oils tend to evaporate more quickly than fragrance oils. The longevity of an essential oil's scent depends on factors such as its purity and the environment in which it is used.
Both oils can oxidise if not stored correctly and lose their potency over time.

Usage and safety
Essential oils are highly concentrated, potent substances that need to be diluted at the proper ratio to ensure safety when applying topically or diffusing. They are created with physical extraction processes, including steam distillation and cold pressing. Essential oils are considered safe for use in aromatherapy and therapeutic purposes, with benefits for the body and mind. They are used in diffusers, massages, therapeutic baths, and skincare. However, it is important to research the specific essential oil to ensure it is safe for the intended use, as some essential oils cannot be used in leave-on products or by certain individuals with health conditions.
Fragrance oils, on the other hand, are synthetically manufactured in labs to mimic the scent of essential oils or other natural materials. They are designed solely to smell pleasant and do not offer the same aromatherapeutic benefits as essential oils. Fragrance oils are commonly used in perfumes, colognes, soaps, candles, and cosmetics. While they can provide a wider variety of scents and blends, they may also contain chemical compounds that can cause adverse skin reactions and other health concerns. It is important to read the safety information provided with fragrance oils and be cautious if you have any skin or fragrance sensitivities.
Both essential and fragrance oils can be used in DIY projects such as homemade soap, candles, and perfumes. When choosing between the two, consider your specific needs and preferences. Essential oils are prized for their natural therapeutic properties, while fragrance oils offer a broader range of scents and are designed to be longer-lasting.
It is important to note that neither essential nor fragrance oils should be ingested, and they should always be handled and used according to safety guidelines.
