Cedrene’s unique aroma has made it an essential ingredient. Its unique aroma is a combination of the transparency and freshness of pine wood and the stability and weight of wood. It does not spoil or become volatile at room temperature and its scent can last several weeks. It is often used as a fixative in high-end perfumes. Cedarene, for example, can be used in conjunction with sandalwood alcohol and vetiver oil to neutralize too much fat gas. This gives the fragrance a deep and dry base note. It is therefore widely used by natural ingredient brands like Lush and L’Occitane.

Cedrene’s biological activity is being gradually explored. Modern pharmacological studies have shown that its cyclic structure can bind to proteins on bacterial membranes. This disrupts membrane integrity, and inhibits the proliferation of pathogenic bacteria like Staphylococcus aureus and Escherichia coli. The MIC can be as low at 0.5-2mg/mL. Cedar essential oil, which contains cedrene, is used in Ayurvedic medicine to treat skin inflammation. It has been shown to inhibit the release inflammatory factors TNF a and IL-6 and alleviate symptoms such as redness and swelling of skin conditions like eczema or acne. Some pharmaceutical companies have used it in formulation research and development for antibacterial gels and anti-inflammatory creams to investigate its potential in the field alternative antibiotics.

Cedrene is a powerful plant-based insecticide that has many advantages. Cedrene has a strong repellent effect against pests that pierce and sucking such as red spider mites and aphids. In field experiments, spraying formulations containing 2% of cedrene reduced the number of insect eggs in crops by 40-60%. This repellent effect could last up to 7-10 days. Its mechanism is to block the olfactory sensors of pests and prevent them from locating the host plant. At the same, it inhibits the spore germinating of pathogenic bacteria, such as wheat Fusarium Graminearum and rice blast fungus. Cedrene is a natural pesticide that can degrade in the soil over 80% within 60 days. It also has a low toxic level for non-target organisms like bees and earthworms. Cedrene has been used in organic tea gardens, ecological orchards and for green pest management.

Cedrene is a new way to upgrade products. In wood coatings its addition can create hydrogen bonds with the resin molecules. This increases the adhesion by 15-20% of the coating film, while increasing the flexibility of film and reducing cracking of wood due to temperature changes. A high-end furniture company added 5% cedrene in wood wax oil. The painted solid wood table did not show any signs of peeling or wrinkling after being tested in an environment ranging from -20 to 60%. Its natural woody scent can also be released up to 12 months. It can be used to coat wardrobes and bookcases and cover the smell caused by wood mildew, formaldehyde, and volatilization. This creates a healthy environment.

Cedrene can be used as a model to explore the mysteries surrounding terpenoids. Sesquiterpene biosynthesis can be studied using the bicyclic structure of its molecule and its double bond positions. Researchers have been able to track the synthesis of sesquiterpenes in cedar cell lines and have identified the role played by farnesyl-pyrophosphate synthase in the process. This has laid the groundwork for mass production of terpenoid compound using genetic engineering. The study of the binding mechanism of FPS with different receptors provides structural reference for the design and development of new spice molecules as well as antibacterial drugs. By methylating these compounds, derivatives that have a stronger aroma or antibacterial properties can be produced. The Journal of Natural Products, Organic Chemistry Communications and other authoritative journals have published relevant results.
