The Natural Debate: Fragrance Oils In Soaps

Fragrance oils are often marketed as natural and used in soaps, but are they really? The answer is complicated. While some fragrance oils are derived from natural sources like plants, flowers, and fruits, they are often created in a lab using synthetic chemicals to replicate natural scents. This means that even natural fragrance oils are not truly natural, as they are not derived directly from nature but are human-made.

On the other hand, essential oils are considered natural as they are extracted directly from herbs, flowers, and plants through steam distillation, a gentle process that ensures the sensitive compounds don't break down.

So, while fragrance oils may be made with some natural ingredients, they are still considered synthetic due to the lab creation process and cannot be labelled as natural on soap products. This distinction is important for consumers who value natural products and wish to avoid synthetic chemicals.

Fragrance oils are synthetic and made in a lab

Fragrance oils are synthetic products made in a laboratory setting. They are created using a mix of aroma chemicals and natural ingredients, such as extracts, essential oils, and resins. While these fragrance oils may contain plant-based components, they are still considered synthetic and cannot be labelled as "natural" on product packaging.

The process of creating fragrance oils involves the isolation of certain aromatic constituents from botanicals. For example, vanillin, an organic compound isolated from the seed pods of vanilla, can be extracted and used as a fragrance oil. However, this compound can also be synthetically produced in a laboratory, yielding a product that is chemically identical to its natural counterpart.

The creation of fragrance oils allows for the replication of pleasant, naturally occurring scents at a lower cost. These synthetic fragrances are often derived from petroleum or its by-products. The use of fragrance oils in various products, such as soaps, candles, and cosmetics, has become commonplace, with synthetic fragrances comprising 85% or more of the products on the market.

While fragrance oils offer advantages in terms of cost and scent variety, it is important to consider their potential impact on health and the environment. Synthetic fragrances can contain chemicals that may cause adverse reactions, such as headaches, sinus irritation, and allergic responses. Additionally, the production and use of these fragrances can contribute to indoor air pollution and have negative ecological consequences.

Natural fragrance oils are made from plants

Plants are made up of multiple aromatic components. For example, Bulgarian lavender contains linalyl acetate, linalool, b-caryophyllene, and terpinen-4-ol, which give lavender its signature floral scent. To make a natural fragrance oil, one of these components is isolated from the plant. These single aromatic chemicals are called isolates and are designated as natural by the International Organization for Standardization.

Next, the isolate is blended with others from a variety of different plants. For example, linalyl acetate from lavender, which has a floral and citrusy scent, could be blended with ethyl acetate from orange, which smells sweet and fruity. These can also be blended with essential oils.

This process has several advantages. Because natural fragrance oils are made up of multiple components from different plants, they smell complex and can be more interesting than a single essential oil. They're also more consistent because they're not as affected by batch variation.

There are also more natural options to choose from. Certain things, like vanilla and strawberry, don't produce essential oils. However, they are made up of components that can be isolated. That means you can enjoy a crisp apple scent that's all-natural.

However, natural fragrance oils do not work well in hot or cold process soap. They are perfect for skincare projects like masks, scrubs, serums, and moisturisers. If you plan to sell your products, you can put "natural fragrance" or "natural fragrance oil" on the label.

Essential oils are natural and extracted from plants, herbs, and flowers

Essential oils are natural and are extracted from plants, herbs, and flowers. They are highly concentrated, volatile, and aromatic essences that are 100% natural. The extraction process involves capturing the essence of the plant's fragrance and beneficial properties, and there are various methods to do this, including steam distillation and cold-press extraction.

Steam distillation involves using a distillation apparatus to hold the plant material and water, cool and collect the steam, and separate the essential oil from the water. The process starts by placing the plant material in a flask and adding distilled water to cover it. The condenser and separator are then assembled, and the flask is heated, turning the water into steam, which carries the essential oil molecules. The steam then passes through the condenser, where it cools and condenses into a mixture of water and essential oil. This mixture then flows into the separator, where the essential oil and water are separated due to their density difference. Finally, the essential oil is collected and stored in a dark glass bottle to protect it from light degradation.

Cold-press extraction is another method used for plants with aromatic peels, such as citrus fruits. This process involves peeling the fruit, crushing or chopping the peels, and placing them in a glass jar with a carrier oil such as jojoba, almond, or coconut oil. The jar is then sealed and stored in a cool, dark place for several weeks, with daily shaking to enhance infusion. After the infusion period, the oil is strained to remove the peel remnants, and the infused oil is transferred to a dark glass bottle for storage.

Essential oils have a wide range of applications, including aromatherapy, cosmetics, and natural healing. They are also used in soap-making, where they can be added to various soap-making methods such as melt and pour or cold process. However, it is important to note that essential oils should always be diluted with a carrier oil before topical use to avoid skin irritation.

In addition to their therapeutic and aromatic properties, essential oils offer versatility in DIY crafts. They can be used to create scented candles, bath bombs, potpourri, rollerball blends, jewellery, room sprays, clay ornaments, reed diffusers, and handmade soaps.

When working with essential oils, it is crucial to prioritise research and understand the specific plant being used, as some plants are toxic or can cause skin irritation. Precautions should also be taken to ensure proper ventilation and avoid fire hazards during the extraction process.

Fragrance oils are made up of 40-80 materials

Fragrance oils are considered synthetic products, despite the fact that they may contain plant-based components. They are made up of a mix of aroma chemicals and natural ingredients, such as extracts, essential oils, and resins.

A single fragrance oil can be composed of 40-80 materials, resulting in complex blends that cannot always be replicated in nature. This means that you can create scents that nature cannot, such as strawberry or vanilla, which do not produce essential oils.

The process of creating a fragrance oil involves isolating a single aromatic chemical, known as an isolate, from a plant. These isolates are designated as natural by the International Organization for Standardization. This isolate is then blended with others from a variety of different plants. For example, linalyl acetate from lavender could be blended with ethyl acetate from orange. These blends can also include essential oils.

The advantage of this process is that fragrance oils are more consistent than essential oils because they are not as affected by batch variation. They also offer more scent variety than essential oils and work well in all projects, including cold and hot process soap. However, they cannot be listed as natural on a label.

Fragrance oils are not suitable for hot or cold process soap-making

Some fragrance oils will fade, while others will stick around for years. Some will even cause the soap to thicken more quickly than usual, or to heat up. In extreme cases, your recipe can start to bubble out of the mould, which is called a "soap volcano".

If you are set on using fragrance oils, it is recommended that you make a small test batch first so that you can see how the fragrance performs and adjust your recipe if necessary. You can also try using recipes with a large percentage of oils that are liquid at room temperature (soft oils), as these give you more time to work.

If you are looking for a more natural option, essential oils are extracted from natural sources such as plants, herbs, and flowers, and they use every aroma component of the plant. This results in a pure and fresh scent that many people love. You can also create your own unique blends with other essential oils. However, there are fewer options available, and there will be natural batch variation.
