What are Essential Oil Grades?

Essential oil grades generally refer to the purity, production process, and purpose of the essential oil. The classification of grades may differ depending on the different essential oil companies. It is because there is no worldwide regulatory authority. Essential oil grades generally fall under the following categories:

Therapeutic-grade essential oils
Food-grade essential oils
Cosmetic or perfume-grade essential oils
Industrial-grade essential oils
Synthetic or fragrance-grade essential oils

Each of these classifications determines the kinds of essential oils that are fit for a particular purpose. Understanding the different essential oil grades helps ensure that one does not waste money on products that are not required. In addition, it also helps prevent the use of a particular essential oil for a purpose that it was not intended for.

What are Cosmetic Grade Essential Oils?

Cosmetic-grade essential oils generally refer to essential oils that are primarily used in the production of beauty products such as shampoo, lotions, cosmetics, perfumes, creams, and other related products. Essential oils that fall under this classification are normally diluted with carrier oils. They are combined with other additives to make them suitable for topical application.

This type of essential oil is produced through a lower-standard production process and mixed with synthetic ingredients. This makes them last longer and have diverse flavors and quality. The dilution process makes this essential oil unfit for therapeutic application. But it is appropriate for making cosmetics and combining with other ingredients to create a desirable scent and consistency.

What are Therapeutic Grade Essential Oils?

Compared to the other grades of essential oils, therapeutic-grade essential oils are produced using a higher standard production process. This ensures that the end product is pure and of high quality. Therapeutic-grade essential oils are extracted from plants through steam distillation or cold pressing. They do not involve any form of dilution or the addition of synthetic ingredients to produce pure essential oils.

In addition to the production process, therapeutic-grade essential oils are subjected to rigorous laboratory tests, such as GC-MS (gas chromatography-mass spectrometry), to ensure that they meet the quality standards. Therapeutic-grade essential oils are primarily used for therapeutic, massage, and aromatherapy purposes.

Some of the commonly used therapeutic-grade essential oils include lavender, peppermint, and tea tree oils among others. Therapeutic-grade essential oils are higher in concentration, aroma, and cost compared to other grades of essential oils.

How Are Essential Oils Graded?

The grading process of essential oils differs from one company to another. However, there are a few things to consider when determining the quality of essential oils.

First, essential oils are produced from medicinal plants. Therefore, it is advisable to purchase essential oils from plants that are organic and free from pesticides.
Secondly, it is important to consider the production process of essential oils. The best essential oils are produced using steam distillation and cold pressing methods. Essential oils that are produced using chemical processes have lower quality.
Thirdly, essential oils should be subjected to quality tests and certifications before use and sale.
The best way to determine the quality of essential oil is by considering the GC-MS tests to ensure the oils are highly potent and close to their natural form.
