What You'll Learn
Synthetic fragrance oils
Synthetic aroma chemicals are used when no essential oil or naturally occurring scent is available. For example, chocolate fudge or blueberry cheesecake fragrances are created synthetically. Synthetic fragrance oils in powder form require a solvent to convert them to a liquid for use in fragrance oil. Solvents help the components of a fragrance burn more easily, blend better, improve fragrance throw, and increase longevity.
Some companies, like CandleScience, create fragrance oils that are extensively tested and rated for performance in soy wax, as well as other natural waxes, wax blends, and paraffin wax. They are also compatible with reed diffusers, room sprays, and bath and body products.

Natural fragrance oils
These oils harness the distinctive essence, or scent, of the plant from which they are derived. They are frequently used in perfumes, flavourings, and medicines. Natural fragrance oils are also used in candles, where the heat from a burning wick increases the wax temperature, gradually releasing an aroma through the evaporation of the oil.

Uses of fragrance oils
Fragrance oils, also known as aroma oils, aromatic oils, and flavour oils, have a wide range of uses. They are used in perfumery, cosmetics, candles, and even food flavouring.
In perfumery, fragrance oils are composed of synthetic aromatic compounds and may also contain natural aromatic compounds. They are formulated according to a required scent profile and are manufactured in a lab to imitate a naturally occurring scent. Natural fragrance oils are synthesised in a laboratory without using any synthetic materials. They are created by combining isolates from various natural aromatic materials or essential oils to create a complex aroma.
In cosmetics, fragrance oils are used in products such as soaps, lotions, bath bombs, and detergents. They are also used in household products like candles, wax melts, and room sprays. When used in candles, fragrance oils are combined with hot wax, and as the wax cools, the fragrance oil is retained. Lighting the candle wick increases the wax temperature, gradually releasing an aroma through the evaporation of the fragrance oil.
Fragrance oils are also used in food flavouring. While essential oils are frequently used for this purpose, fragrance oils are used when no essential oil or naturally occurring scent is available. For example, fragrance oils are used to create Chocolate Fudge or Blueberry Cheesecake fragrances.
Additionally, fragrance oils can be used in at-home crafts and scents, as well as in religious rituals and special occasions in certain regions, such as the Middle East and some Asian countries like India and Pakistan.

Fragrance oil shelf life
The average shelf life of fragrance oils is about six to twelve months, depending on their composition. They can last longer if stored in optimal conditions, which is typically in a cool, dark place away from light, heat, and oxygen. The fragrance oil will likely spoil faster if it contains more natural ingredients.
You can determine if a fragrance oil has gone bad by its smell—if it smells off, different, or bad, or if the scent fades faster than normal.
The shelf life of fragrance oils is an important consideration, especially when purchasing. It is recommended to buy only the amount of fragrance oil that you will use within six months to a year.
The longevity of fragrance oils can be influenced by various factors, including time, temperature, exposure to air and light, and the shelf life of the raw materials used. Synthetic fragrance oils, for example, tend to hold their fragrance longer than natural oils due to their artificial chemical components.
