OEM Factory Direct Supply Turmeric Root Essential Oil Rich in Curcumin Steam Distilled Curcuma Longa Oil Wholesale Bulk Supplier

Product Overview

Curcuma longa, the source plant, is native to South Asia and widely cultivated in India, China, and Southeast Asia. The essential oil is extracted from the underground rhizome, which is harvested during the plant’s active growth phase. The steam distillation method ensures minimal thermal degradation of sensitive compounds, maintaining the integrity of curcumin and other phytochemicals.

Typical grades of turmeric essential oil include standard, high-curcumin, and premium grades, with curcumin content ranging from 2% to 8% depending on the source, processing method, and harvest conditions. The oil is typically clear to pale yellow in color and has a warm, earthy, slightly spicy aroma with a hint of sweetness.

Key Characteristics & Technical Properties

• Chemical Composition: Dominated by curcuminoids (curcumin, demethoxycurcumin, bisdemethoxycurcumin), along with volatile terpenes such as turmerone and zingiberene.
• Curcumin Content: Typically between 2% and 8%, with higher concentrations indicating superior quality and potency.
• Odor: Warm, earthy, slightly spicy, with a subtle sweetness.
• Color: Pale yellow to amber, depending on curcumin concentration and processing.
• Specific Gravity: Approximately 0.88–0.90 g/cm³.
• Boiling Point: Varies due to complex composition, but volatile components typically distill between 180–230°C.

Harvesting & Production Process

The rhizomes are harvested manually during the dry season when the plant is mature. After harvesting, the roots are cleaned, dried, and ground into a coarse powder. The powder is then subjected to steam distillation in closed-loop stills to extract the essential oil. The distillation process is carefully controlled to maintain temperature and pressure, ensuring optimal yield and quality.

Post-distillation, the oil is filtered to remove impurities and stored in dark glass bottles to prevent oxidation. The oil is typically tested for purity, curcumin content, and microbial safety before being packaged for wholesale distribution.

Quality & Grading Standards

Quality is determined by several key parameters:

• Curcumin content (measured via HPLC or spectrophotometry)
• Presence of adulterants (e.g., synthetic curcumin or other oils)
• Odor and aroma profile consistency
• Color and clarity
• Microbial and chemical stability

International standards such as ISO 9239 and ASTM D4458 provide guidelines for essential oil testing and quality control. Reputable suppliers ensure batch-to-batch consistency and provide certificate of analysis (CoA) for each shipment.

Common Uses & Applications

Turmeric essential oil is widely used in aromatherapy, natural skincare, and holistic wellness products due to its anti-inflammatory, antioxidant, and antimicrobial properties.

• Aromatherapy: Used in diffusers, inhalers, and massage oils for its calming and uplifting effects.
• Skincare: Incorporated into face serums, creams, and body lotions to support skin health and reduce inflammation.
• Food & Beverage Industry: Used as a natural flavoring and colorant in spice blends and traditional recipes.
• Complementary Medicine: Used in formulations for joint pain, digestive support, and respiratory health.
• Household & Cleaning Products: Applied in natural cleaning solutions for its antimicrobial properties.

Typical Packaging & Export Context

The oil is commonly packaged in dark glass bottles (10ml, 50ml, 100ml, 500ml, or 1L) to protect against light and oxidation. Bulk shipments are available in drums or IBC (Intermediate Bulk Containers) for large-scale buyers.

It is widely traded globally, with major markets in North America, Europe, and Asia. Export compliance includes adherence to international regulations on essential oils, including labeling requirements and safety standards. The product is often supplied with a certificate of analysis and batch number for traceability and quality assurance.
