Another terpene called farnesol also has anti-aging and skin-smoothening properties, which make them ideal for products like hydrating face masks. Nerolidol is also a common ingredient in the industry, which improves the absorption of other ingredients into the skin, making them more effective.
Terpenes Facts and Statistics
You can find terpenes almost everywhere in the natural world. Here are some terpenes statistics and facts you may not know just yet!
5. There are over 20,000 different terpene compounds found in nature.
Plants that contain terpenes grow and thrive in all sorts of conditions. Scientists found that some species that grow in areas without many resources, such as deserts, secrete terpenes to inhibit a competitor plant’s growth.
Plants are not the only organisms that contain terpenes. Certain insects like millipedes, moths, and beetles also produce them, as well as bacteria and fungi.
6. Some terpenes, like limonene, can make up more than 90% of the essential oil in certain citrus fruits.
While you can find limonene in many fruits, the highest concentrations are in the peels of oranges. Manufacturers extract the oil from the rind and distribute it in cosmetics, cleaning products, and insect repellants.
7. Pinene is one of the most abundant terpenes in all other natural plant life on Earth.
You can extract pinene from pine trees, flowering plants like lavender and juniper, and a wide array of rosemary, parsley, and basil.
Additionally, there are two types of this compound: alpha and beta-pinene. To differentiate the two, you only need to remember that alpha-pinene is oil and ethanol-soluble, while beta-pinene is ethanol and water-soluble.
8. Experts estimate the terpene market to reach $1.01 billion by 2028.
Due to increasing demand, the market projects that the terpene industry will develop at a Compound Annual Growth Rate (CAGR) of 8.30% from 2021 to 2028.
Many industries use terpene in their products, such as resin for rubber, adhesive, paper, and pulps. Terpenes are also a staple in the food and pharmaceutical sector because manufacturers use them as added flavorings.
9. Different terpenes wheels give a visual overview of the compounds by flavor and source, much like a color wheel.
While there are different variations of the terpene wheel, one of the common characteristics is grouping similar flavors. An example is that eucalyptol and guaiol taste spicy, while linalool and beta-ocimene taste sweet.
10. Myrcene is considered the “Mother of All Terpenes” as it’s the most abundant compound in many flowers.
Myrcene synergizes other terpenes’ activities and helps your body absorb other ingredients more effectively. Its ability to work with other terpenes makes it a valuable compound for creating the entourage effect in particular flowers.
Extraction and Analysis
Much like other common components in production, there are more ways than one to extract and analyze terpenes. Here’s how companies collect terpenes from their source and why examining them is essential:
11. Steam distillation is the essential oil industry’s most common method to extract terpenes from plants.
The process passes steam through the plant, which causes the terpenes molecules to vaporize. The compounds then go through a cooling system, condensing into a liquid. Manufacturers separate the fluid to collect the resulting essential oil containing the terpenes.
The advantage of steam distillation is that equipment is reasonably inexpensive, making it ideal for even smaller brands to start their in-house manufacturing. It’s also possible to scale up for more extensive operations.
12. Terpene analysis in product development optimizes the terpene profile of a product for maximum efficacy.
Analyzing terpenes means that experts can understand the unique properties each one possesses and how they can work together to achieve desired effects. During this process, businesses can also determine if terpenes adversely impact the body, in what concentration, and if using it with another compound is possible.
The analysis is also essential due to possible contaminants in the products. By performing these steps during development, companies can maintain product quality and consistency that are safe for the market.
13. New research suggests terpene efficacy against COVID-19.
A Forbes article states that scientists from Israel found that a combination of terpenes could be more effective in treating COVID-19-related inflammation than corticosteroids. The terpene treatment reduced cytokine production by up to 90%, while corticosteroids only reduced it by 30-40%.
However, further research is required before confirming that the compounds can fully treat the virus.
