A carrier is a base ingredient used to enhance the evaporation or diffusion of a fragrance or flavor material. They are commonly used in many consumer products such as food, tobacco, and perfumes. Alcohol is often used as a carrier for perfumes, but natural oils such as olive oil, jojoba oil, and coconut oil can also be used as carriers for essential oils. In the case of food products, carriers are used to alter the flavor of the food through the sense of smell. These carriers can be natural, nature-identical, or artificial.

Alcohol is a common carrier for fragrances, enhancing the diffusion of a scent
A carrier is a base ingredient used to enhance the evaporation or diffusion of a fragrance material or the fragrance blend. Alcohol is the carrier of choice for fine fragrances. It is a crucial ingredient in most perfumes, serving as a solvent, stabilizer, and carrier, enhancing fragrance profiles and longevity in perfumery. The alcohol percentage in perfumes determines their strength, with higher alcohol content found in lighter formulations. For example, Eau de cologne contains 70-80% alcohol, while Eau de Parfum contains 80-90%.
Perfumer's alcohol is used when mixing perfumes and combining with essential oils and fragrance notes to produce aromatic perfumes. These perfumes can be used in spray bottles of all sorts, from perfume and cologne bottles to diffusers, and even for household cleaning products, such as window cleaners and air fresheners. The alcohol in perfume also prevents the degradation of fragrance oils due to microbial growth, thus stabilizing fragrances by preserving the integrity of the fragrance compounds. The high alcohol content in perfumes helps the perfume evaporate quickly once it’s applied to the skin.
The recommended carrier can vary depending on the product format. Carrier oils such as coconut, jojoba, or grapeseed are rich in fatty acids, which have a similar structure to the natural oils found on the skin. A preferred carrier for an aromatic body oil may be jojoba oil as it absorbs quickly and aids in moisturizing the skin without leaving any greasy effect. Natural oils like olive oil, jojoba oil, and many others can be used as carriers for essential oils.
Alcohol carriers will carry the scent further because the alcohol evaporates off and takes some of the fragrance with it. On the other hand, an oil carrier will keep the scent close to the skin because the oil soaks into the pores. Many fragrance ingredients are quite pungent on their own, and the scent is often too strong to wear without a carrier. Alcohol is ideal for fully diluting the ingredients and functions as a preservative.

Carrier oils are used to dilute essential oils, making them safe for skin application
A carrier is a base ingredient used to enhance the evaporation or diffusion of a fragrance material or the fragrance blend. In the case of essential oils, carrier oils are used to dilute the highly concentrated oils, making them safe for skin application. Essential oils, if applied directly to the skin, can cause reactions such as severe irritation, flushing, or burning.
Carrier oils are usually vegetable oils, such as coconut oil or avocado oil, derived from the seeds, kernels, or nuts of a plant. They are readily absorbed by the skin and do not evaporate quickly, giving them strong staying power, which makes them good base materials for many applications.
There are many different carrier oils available, each with its own unique properties and benefits. The best carrier oil for you will depend on your skin type, your preferences, and what you're using the oil for. For example, jojoba oil is one of the most popular carrier oils because it is full of beneficial nutrients, including vitamins A, D, and E, making it great for your skin. It is also known to be the carrier oil that is closest to mimicking the natural oil secretions in human skin. This makes it an excellent moisturizer for use on the face and neck that can otherwise feel greasy with other carrier oils.
When diluting essential oils with a carrier oil, it is important to follow dilution guidelines. The National Association for Holistic Aromatherapy recommends using 2.5% to 10% essential oils when creating massage and body oils, with the rest of the mixture being the carrier oil. The ratio of essential oil dilution is lower in facial treatments. People with sensitive skin should use 0.5% to 1% of essential oils, while those with less sensitive skin can use 1% to 2.5%.

Natural polymers are an effective, low-cost option for a fragrance carrier
A carrier is a base ingredient used to enhance the evaporation or diffusion of a fragrance material or the fragrance blend. Alcohol is the most commonly used carrier for fine fragrances, but natural oils such as olive oil, jojoba oil, and coconut oil can also be used as carriers for essential oils.
Natural polymers are environmentally friendly and cost-effective. They can be used to create a range of fragrance-capturing polymer forms, including nanoparticles, capsules, micelles, inclusion complexes, or emulsions. These polymers can be used in various applications, such as toiletries, air fresheners, and cosmetics, to create an elegant, welcoming, or exhilarating environment.
Additionally, natural polymers have different molecule weights and viscosities, making them suitable for targeted applications. They can be combined with other natural carrier oils to create custom blends for skincare and other applications. Natural carrier oils are readily absorbed by the skin and have strong staying power, making them good base materials. They also have nourishing properties, making them excellent for use in skincare products.

Synthetic materials are chosen for their aromatic qualities, providing a strong initial impression
A carrier is a base ingredient used to enhance the evaporation or diffusion of a fragrance material or the fragrance blend. Alcohol is the carrier of choice for fine fragrances, but natural oils (such as olive oil, jojoba oil, and coconut oil) can be used as carriers for essential oils. Carriers are fundamental when preparing perfumes, as they dilute the fragrance oils and make them safe for use on the skin.
Synthetic materials are often chosen as carriers in perfume development for their aromatic qualities, providing a strong initial impression. Synthetic carriers can be used to control the release of volatile ingredients over an extended period. This is particularly important in the flavor and fragrance industry, where fragrance compounds have a limited lifespan due to premature evaporation and degradation. Synthetic materials, such as polymers, are low-cost and versatile, making them ideal candidates for fragrance carriers.
While synthetic carriers offer strong initial impressions, natural carrier oils are also commonly used. These oils, derived from plants, are rich in fatty acids and have a similar structure to the natural oils found on the skin. Jojoba oil, for example, is a popular choice as it absorbs quickly and moisturizes the skin without leaving a greasy residue. Natural carrier oils have been used as perfume bases for hundreds of years and are known for their strong staying power.
The choice between synthetic and natural carriers ultimately depends on the desired format, performance, and application of the fragrance product. Alcohol, for instance, carries the scent further as it evaporates and takes the fragrance with it. In contrast, oil carriers keep the scent closer to the skin as the oil soaks into the pores. Therefore, while alcohol-based perfumes may have better projection, oil-based perfumes offer greater longevity.

The type of carrier used will influence the longevity and range of a fragrance
A carrier is a base ingredient used to enhance the evaporation or diffusion of a fragrance material or the fragrance blend. The type of carrier used will influence the longevity and range of a fragrance. Alcohol is the carrier of choice for fine fragrances, but natural oils (olive oil, jojoba oil, and many others) can be used as carriers for essential oils.
Alcohol lifts a fragrance as it evaporates, and the scent will radiate outward. With alcohol-based perfumes, a little goes a long way. However, what you gain in projection, you lose in longevity. Alcohol-based perfumes dry out the skin. On the other hand, an oil-based perfume will keep the scent close to your body, and the scent increases with body heat. Oils are moisturising and stick to the skin longer than alcohol, so the scent will stay with you longer. However, what you gain in longevity, you lose in range.
The recommended carrier can vary depending on the product format. Carrier oils such as coconut, jojoba or grapeseed are rich in fatty acids, which have a similar structure to the natural oils found on the skin. A preferred carrier for an aromatic body oil may be jojoba oil as it absorbs quickly and aids in moisturising the skin without leaving any greasy effect. Synthetic materials can also be used as carriers, and they are chosen for their slight aromatic qualities at varying strengths. They provide the benefit of having an immediate and strong initial impression, as well as a controlled release of volatile ingredients over an extended period of time.
The longevity of a fragrance is also influenced by its concentration. A higher concentration of fragrance material will result in greater staying power. However, a higher volatility will result in better projection but lower longevity. For example, citrus oils have higher volatility and thus have better projection but lower longevity.
