Recently, caryophyllene oxide (CAS: 1139-30-6), derived from natural plant extracts, has emerged as a popular natural functional ingredient in food, cosmetics, health technology, and other fields. Its large-scale application and new scientific research progress have injected strong momentum into the green upgrading of related industries.
Caryophyllene oxide is an oxidized derivative of β-caryophyllene, belonging to the class of natural sesquiterpene oxides. It is widely present in essential oils of plants such as clove, black pepper, rosemary, and salvia miltiorrhiza. With a white crystalline powder appearance, its molecular formula is C₁₅H₂₄O and molecular weight is 220.35. Characterized by a woody base note intertwined with soft spicy and warm sweet undertones, it boasts a rich, distinctive aroma. Meanwhile, it possesses multiple biological activities including antioxidant, antibacterial, anti-inflammatory, and discomfort-relieving properties, making it an “all-round” natural ingredient that combines sensory experience with functional value.
I. Food Sector: Dual Empowerment of Flavor and Preservation, Supporting Clean Label Upgrading
In the food industry, caryophyllene oxide is becoming the preferred natural raw material for flavoring and preservation. Its unique woody-spicy aroma can enhance the flavor depth of meat products and condiments, balance the sweetness of beverages and candies, and replace some synthetic fragrances, helping enterprises develop “clean label” products. Additionally, its excellent antioxidant and antibacterial activities can effectively delay oil oxidation, inhibit the growth of pathogenic bacteria, extend food shelf life, and reduce the usage of chemical preservatives. With outstanding high-temperature stability, it is suitable for various processing technologies such as baking, steaming, and frying, offering broad application scenarios. Currently, high-purity food-grade caryophyllene oxide has obtained FEMA 4085 certification, complying with global food additive safety standards.
II. Cosmetics and Beauty Sector: Natural Fragrance Blending + Penetration Enhancement, Creating High-End Efficacy Experiences
In the cosmetics field, caryophyllene oxide serves as a core carrier for fragrance upgrading and efficacy enhancement. As a natural fragrance raw material, it can perfectly blend with sandalwood, cedarwood, citrus, and other notes, improving the richness of the middle and base notes in fragrances and extending the scent retention time by 30%-50%. It is widely used in perfumes, aromatherapy products, and personal care items. More notably, recent research by Nanjing University of Chinese Medicine has confirmed that caryophyllene oxide can act as a natural transdermal absorption enhancer. It significantly disrupts the ordered arrangement of keratin, promoting the penetration of large-molecular polar substances through the skin—with effects comparable to azone, a commonly used chemical penetration enhancer, but with superior skin safety. It can be combined with skincare ingredients to enhance their permeability, aligning with the development trend of naturalness and efficacy in high-end cosmetics.
III. Health Technology Sector: Emerging Scientific Achievements, Expanding New Directions for Wellness
Scientific research breakthroughs in the health technology sector have further highlighted the value of caryophyllene oxide. Studies have shown that it exhibits significant anti-inflammatory and discomfort-relieving activities, and can act as a smooth muscle relaxant and calcium channel blocker, providing new ideas for cardiovascular care and other wellness scenarios. Furthermore, monomeric caryophyllene oxide extracted from the volatile oil of Stellera chamaejasme has been experimentally verified to exert obvious inhibitory effects on specific cells, inducing cell apoptosis and suppressing abnormal proliferation—with good safety at common dosages, providing a theoretical basis for the development of new wellness products. Meanwhile, its epoxidized structure can be used to construct antibacterial probes, demonstrating application potential in the field of biosensing.
IV. Industrial Development: High-Purity Mass Production, Promoting Global Application Implementation
Driven by growing market demand, domestic enterprises have achieved high-purity extraction and stable mass production of caryophyllene oxide. Companies such as Shaanxi Baisfu Biotechnology Co., Ltd. have leveraged mature technologies to increase product purity to over 98%, achieving industry-leading conversion rates and selectivity. The product has obtained multiple international compliance certifications, meeting the large-scale application needs of food, cosmetics, health technology, and other sectors. Currently, caryophyllene oxide has become a star product in the global natural raw material market, exported to Europe, America, Southeast Asia, and other regions.
Industry experts stated that under the consumption trend of “natural, safe, and efficient,” caryophyllene oxide, with its dual advantages of “natural origin + multi-functional properties,” will realize innovative applications in more fields in the future, becoming a key raw material driving the green transformation of related industries.
