Protecting the Integrity of Natural Oils
Citrus oils are valuable, volatile, and sensitive to storage conditions. Whether you’re managing bulk orange oil, drummed d-Limonene, or a rotating stock of citrus distillates, proper storage and handling are critical to maintaining product stability, safety, and compliance.
In this update, ICC shares best practices for bulk citrus oil storage to help your team minimize degradation, reduce hazards, and preserve batch consistency from delivery to final use.
Understanding the Properties of Citrus Oils
Citrus oils are comprised mainly of terpenes, primarily d-Limonene, which are:
- Highly volatile and prone to evaporation
- Reactive to heat, light, and oxygen
- Flammable with low flash points
- Prone to oxidation, which can lead to odor shift or reduced efficacy
These factors must be considered when planning storage systems, packaging, and facility layout.
Storage Environment Recommendations
Temperature Control
- Ideal range: 50°F to 77°F (10°C to 25°C)
- Avoid exposure to direct sunlight or excessive ambient heat
- Use temperature-controlled indoor storage where possible
Air and Moisture Exposure
- Store in sealed, airtight containers with minimal headspace
- Use nitrogen blanketing in bulk tanks to prevent oxidation
- Avoid frequent opening of drums to reduce vapor loss
Light Sensitivity
- Use UV-blocking containers or store in dark indoor spaces
- For long-term storage, stainless steel tanks are preferred
Packaging and Compatibility
Drums and Totes
- ICC ships citrus oils in lined steel drums, HDPE drums, or IBC totes, depending on client needs
- Ensure packaging is UN-rated for flammable liquids
- Do not store citrus oils in aluminum or unlined metal containers, which may react with terpenes
Gaskets and Seals
- Use EPDM, Teflon, or Viton seals for valves and pumps
- Avoid rubber gaskets that may degrade or leach contaminants
Safety Considerations in Bulk Storage
- Ensure proper ventilation to prevent vapor buildup
- Store away from open flames or ignition sources
- Clearly label containers with product name, UN number, and hazard class
- Follow all OSHA and NFPA 30 guidelines for flammable liquids
- Implement spill containment systems in storage areas
Shelf Life and Inventory Rotation
- Most citrus oils are stable for 12–18 months when stored correctly
- Rotate inventory on a first-in, first-out (FIFO) basis
- Request ICC’s stability and shelf-life documentation for reference
