1. Core Definition and Product Attributes of CAS 8000-48-4
Classified as a volatile plant essential oil, Eucalyptus oil with CAS number 8000-48-4 is extracted from the fresh leaves of Eucalyptus globulus. Its main functional active ingredient is 1,8-cineole (commonly known as eucalyptol), which determines the core properties and application scenarios of the oil.Commercial-grade finished products generally feature a cineole content ranging from 70% to 85%, acting as the key evaluation index for product grading and industrial matching.
High-quality Eucalyptus Oil CAS 8000-48-4 presents as a transparent, colorless or pale yellow liquid, with a pure and fresh camphoraceous aroma. In terms of solubility, it is slightly soluble in water, while being completely miscible with ethanol, diethyl ether, and various organic solvents. This excellent compatibility allows it to seamlessly integrate into various formulation systems of daily chemical products, personal care products, and fragrance blending.
What buyers must understand is that CAS 8000-48-4 corresponds to a natural complex mixture, rather than a single pure chemical compound. Multiple factors, including the cultivation origin, harvest cycle, and extraction process, can lead to subtle fluctuations in the proportion of its components. Professional and reliable eucalyptus oil manufacturers will provide a complete Certificate of Analysis (COA) for each production batch, covering data on eucalyptol content, specific gravity, refractive index, and optical rotation, to support customers' quality inspections.Botanical source identification is also a key quality control link. Eucalyptus globulus is the standard raw material for the commercial CAS 8000-48-4 product. In contrast, other eucalyptus species such as Corymbia radiata and Eucalyptus citriodora produce essential oils with different component proportions and functional characteristics. For example, E. citriodora oil is rich in citronellal rather than citrus-like compounds, leading to significantly different antibacterial and respiratory care effects. Therefore, verifying the botanical source via COA documents is necessary for standardized formulation production.
2. Steam Distillation Technology and Modern Production Standards
Mainstream Industrial Extraction Process
Steam distillation is the most widely adopted and mature production technology for natural Eucalyptus Oil CAS 8000-48-4 in the industry. The production process begins by crushing fresh eucalyptus leaves and placing them into a sealed distillation device. High-temperature saturated steam penetrates the plant material, causing the internal volatile essential oil components to evaporate.The mixed steam and oil vapor is then transported to a condensation system for cooling and liquefaction, followed by automatic oil-water separation in professional separators. The crude oil obtained is further filtered and refined to remove impurities, ultimately forming qualified finished Eucalyptus Oil.
This physical extraction method effectively preserves natural active substances in eucalyptus oil without introducing chemical solvent residues, fully meeting the safety requirements of cosmetics, aromatherapy and daily chemical industries. The mainstream 80% cineole high-quality Eucalyptus Oil supplied by formal factories all adopts this process. Although solvent extraction technology exists in small-batch production, it is rarely used in high-end civilian product manufacturing due to potential residual risks.
Modern Factory Quality Control Upgrades
Modern standardized production plants implement real-time monitoring of temperature and pressure parameters throughout the distillation process to stabilize cineole content and ensure batch-to-batch product consistency.At the end of each production cycle, product samples are sent to a professional laboratory for gas chromatography (GC) testing, and only products that meet the standard specifications can enter the packaging and shipping chain. In recent years, the industry has brought about two major technological upgrades. Small-scale eco-factories have popularized solar-assisted distillation equipment, which both reduces energy consumption and production costs, and ensures stable oil production.At the same time, leading export enterprises have added GC-MS composite testing for each export batch, which can accurately detect trace adulterants that cannot be identified by conventional GC testing, greatly improving product purity and quality stability.
3. Core Application Scenarios of Eucalyptus Oil CAS 8000-48-4
Benefiting from its excellent antibacterial performance, deodorizing ability and natural fresh fragrance, Eucalyptus Oil CAS 8000-48-4 has become a versatile essential oil raw material widely used in multiple downstream industries.
Aromatherapy and Personal Care Industry
Steam-distilled natural Eucalyptus Oil is a classic raw material for aromatherapy diffusers, body massage oils, bath products and skin care formulations. It is favored by formulators for its refreshing olfactory experience and mild soothing effects. To ensure product safety and usability, the industry has formed standardized dosage ranges: aromatherapy compound oils are usually diluted with base oil at a proportion of 1%-3%; leave-on skin care products control the addition amount below 0.5% to avoid skin irritation; rinse-off bath gels and body washes adopt a dosage of 0.1%-0.5%. The specific proportion needs to be adjusted according to the actual cineole content of the raw oil.
Household Detergent and Cleaning Industry
In the field of daily cleaning, Eucalyptus Oil CAS 8000-48-4 is commonly added to laundry detergent, household surface cleaners and antibacterial spray products. It can not only endow cleaning products with natural fresh fragrance, but also assist in improving antibacterial and decontamination effects. In laundry products, the conventional addition ratio is 0.1%-0.3%, serving as a fragrance freshening ingredient; in hard surface cleaners matched with surfactants, the dosage is controlled at 0.2%-0.5%. Industrial purchasers need to verify the compatibility between Eucalyptus Oil and their own surfactant systems to prevent product turbidity and precipitation at low temperatures.
Other Industrial Scenarios
In addition to mainstream applications, this product is also widely used in air freshener preparation, pet care products and high-end essence blending. Enterprises in different industries can select Eucalyptus Oil of corresponding cineole grades according to their formulation standards and product positioning to achieve the best use effect.
4. Global Market Status and Industry Development Trends
Driven by the global boom in natural and clean-label raw materials, the overall market size of Eucalyptus Oil maintains a steady upward trend. More and more daily chemical and personal care brands are replacing synthetic aromatic chemicals with natural plant essential oils, continuously expanding the market share of Eucalyptus Oil CAS 8000-48-4.
According to industry market research data, the global Eucalyptus Oil market scale was between USD 180 million and 220 million in 2024, and it is expected to maintain a compound annual growth rate of 4%-6% from 2024 to 2030. The Asia-Pacific and North American markets are the main growth engines, with strong consumer demand for natural green cleaning products and plant-based personal care ingredients.
China is one of the core export bases of Eucalyptus Oil CAS 8000-48-4 in the world, winning the trust of global buyers with stable supply capacity and cost-effective pricing. In contrast, Australia, as the origin of Eucalyptus globulus, mainly supplies high-end premium-grade essential oil with high cineole content at a higher market price. India and South Africa, as emerging suppliers, mainly meet the regional market demand.
In actual procurement scenarios, high-end aromatherapy brands tend to choose Australian high-purity products or high-grade Chinese Eucalyptus Oil, while industrial detergent manufacturers pay more attention to cost performance and stable batch quality. Due to the influence of seasonal climate, leaf harvest volume and international logistics costs, the market price of Eucalyptus Oil will fluctuate periodically. Therefore, long-term cooperative contracts with reliable Chinese exporters can effectively avoid supply shortages and production delays.
5. Quality Verification and Bulk Procurement Guidelines
To ensure product qualification and stable downstream production, buyers need to strictly check multiple key indicators before bulk purchasing Eucalyptus Oil CAS 8000-48-4.
CAS Specification and Core Ingredient Verification
First, it is necessary to confirm that the purchased product is standard Eucalyptus Oil CAS 8000-48-4 to avoid purchasing alternative or counterfeit products. Cineole content is the core evaluation standard of product quality. All products marked with 80% cineole specification must be accompanied by official GC test reports as valid proof.
Industry insiders need to be alert to common adulteration behaviors in the market. Unscrupulous suppliers often use turpentine, synthetic cineole and low-grade eucalyptus oil for blending and dilution. A single cineole data on COA cannot fully prove product purity. It is recommended that buyers ask suppliers for complete GC chromatograms to detect abnormal changes in trace components such as α-pinene, limonene and camphene, so as to identify reconstituted and diluted inferior products.
Standard Purity Detection Method
Professional laboratory Gas Chromatography testing is the only authoritative means to verify the purity and component proportion of Eucalyptus Oil. Simple visual observation can only identify obvious inferior products and cannot detect trace dilution and adulteration. Formal and qualified suppliers will take the initiative to provide complete COA and MSDS safety documents for each batch of products.
International Compliance and Shipping Standards
Products exported to different regions need to meet local regulatory requirements. EU market shipments must comply with REACH registration and CLP labeling specifications; US sales need to meet FDA supervision standards according to cosmetic or daily chemical application attributes; Canadian consumer products require bilingual English-French label identification. Buyers should confirm that suppliers can provide complete compliance documents in advance according to the destination market.
In terms of packaging and transportation, Eucalyptus Oil is uniformly packed in standard blue iron drums or plastic drums for industrial export. All packaging and loading operations strictly comply with UN dangerous goods packaging specifications for essential oil transportation. Before shipment, both parties need to confirm the correct HS code and complete customs declaration documents to ensure smooth customs clearance.
