Eucalyptus Oil CAS 8000-48-4 | 70-85% 1,8-Cineole | USP Grade | Bulk Factory Price

• Eucalyptus Oil (INCI Name: Eucalyptus Globulus Leaf Oil, CAS 8000-48-4) is a natural volatile essential oil extracted by steam distillation from fresh leaves and branches of Eucalyptus trees. It appears as a colorless to pale yellow transparent liquid with a characteristic cooling and refreshing aroma.
  
  
• Its main active ingredient is 1,8-cineole (eucalyptol), with a typical content of 70% - 85%. Eucalyptus oil exhibits expectorant and antitussive, antibacterial and anti-inflammatory, cooling and analgesic, and insect repellent properties.
  
  
• This versatile natural ingredient is widely used in pharmaceutical preparations (cough syrups, inhalants), personal care products (toothpastes, soaps, insect repellents) and food flavorings industries.
  
  
• As a professional source manufacturer, we supply high-quality eucalyptus oil that meets Chinese Pharmacopoeia (CP), United States Pharmacopeia (USP) and European Pharmacopoeia (EP) standards, with stable and consistent bulk supply capacity for global customers.

1. Well-Defined Standardized Active Ingredients

Guaranteed 1,8-Cineole Content: Our eucalyptus oil features a consistently standardized 1,8-cineole (eucalyptol) content of 70%–85%, the primary bioactive compound responsible for all its therapeutic and functional properties.

Multi-Target Synergistic Action: In addition to eucalyptol, it naturally contains α-pinene, limonene and other terpenoid compounds. These components work synergistically to deliver broader-spectrum biological activity compared to isolated single chemical ingredients.

2. Exceptional Natural Benefits

Expectorant & Respiratory Support: Scientific studies confirm it effectively relieves cold symptoms, promotes expectoration, suppresses coughs and clears nasal congestion. It is the core active ingredient in numerous over-the-counter (OTC) cough and cold medications.

Antibacterial & Preservative: Exhibits natural disinfectant and bactericidal properties, making it an ideal active ingredient for natural preservatives and household cleaning products.

Cooling & Analgesic: Produces an immediate cooling sensation upon topical application, helping to relieve muscle aches, joint pain and neuralgia.

Natural Insect Repellent: Serves as a highly effective active component in natural mosquito and insect repellent formulations.

1. Pharmaceutical Preparations (Core Application)

Eucalyptus oil and its core active ingredient 1,8-cineole (eucalyptol) have a long-established history of use in respiratory and topical medicines:

Respiratory Medications: Formulated into inhalants, cough syrups and throat lozenges for treating colds, nasal congestion and coughs. Clinical studies confirm that 1,8-cineole effectively relieves nasal congestion, headache and associated cold symptoms.
