Overview

D Limonene is a naturally occurring cyclic terpene with the molecular formula C₁₀H₁₆, derived primarily from citrus fruit peels. This clear, colorless liquid exhibits a characteristic pleasant citrus odor and serves as a versatile industrial chemical with applications spanning solvents, cleaning agents, fragrances, and chemical intermediates. With its relatively low toxicity profile and biodegradable nature, D Limonene has become increasingly popular as an environmentally friendly alternative to traditional petroleum-based solvents in numerous industrial processes.

Key Applications

  • Industrial Solvent: Effective for degreasing, paint removal, and cleaning applications due to its excellent solvency properties for oils, waxes, and resins
  • Fragrance and Flavoring: Widely used in cosmetics, personal care products, and food applications for its natural citrus scent and flavor profile
  • Extraction Processes: Serves as an extraction solvent for essential oils, natural compounds, and pharmaceutical intermediates
  • Chemical Manufacturing: Functions as a chemical intermediate and polymer precursor in the production of resins, adhesives, and specialty chemicals

Safety & Handling

D Limonene has a flash point of 48°C, classifying it as a combustible liquid requiring appropriate fire safety precautions. Use in well-ventilated areas or with local exhaust ventilation to prevent vapor accumulation. Personal protective equipment should include chemical-resistant gloves, safety glasses, and appropriate respiratory protection when handling in confined spaces. The autoignition temperature of 237°C provides a reasonable safety margin for most industrial applications, but standard hot work precautions should be observed.

Storage & Shelf Life

Store D Limonene in tightly sealed containers away from heat sources, ignition sources, and incompatible materials. Recommended storage temperature is below 25°C in a cool, dry, well-ventilated area. The product is incompatible with strong oxidizing agents and should be kept away from acids and bases. When stored properly in original containers, D Limonene maintains stability for extended periods. Always check containers for integrity and avoid prolonged exposure to air to prevent oxidation.

Frequently Asked Questions

What is D‑Limonene (CAS 5989-27-5) and what is it used for?
D‑Limonene (C10H16, CAS 5989‑27‑5) is a clear, colorless to pale yellow terpene solvent with a citrus odor used as an industrial solvent and laboratory reagent. It is commonly used for degreasing, solvent formulations, coatings, polymer processing and analytical chemistry applications.
How should D‑Limonene be stored and what is its typical shelf life?
Store in a cool, dry, well‑ventilated area away from heat, sparks and open flame in tightly closed, compatible containers and away from strong oxidizers. Typical shelf life is 12–24 months depending on grade and packaging; refer to the Certificate of Analysis (COA) for lot‑specific stability information.
What safety precautions and personal protective equipment (PPE) are recommended when handling D‑Limonene?
D‑Limonene is a flammable liquid and can cause skin or eye irritation and possible sensitization; use proper ventilation, flame control, chemical‑resistant gloves (e.g., nitrile), safety goggles and grounding for transfer operations. Always consult the Safety Data Sheet (SDS) for detailed emergency, first aid and firefighting instructions.
How do different concentrations or grades of D‑Limonene affect performance?
Purity and grade (technical, reagent, stabilized or aromatic grades) affect solvency strength, odor intensity and stability; higher‑purity material generally provides stronger solvency and more consistent analytical performance. Stabilized grades include antioxidants to reduce oxidation and odor change, while diluted or blended concentrations lower solvency power and evaporation rate.
What documentation can I request for D‑Limonene?
Suppliers typically provide a Safety Data Sheet (SDS), Certificate of Analysis (COA), Technical Data Sheet (TDS) and, on request, analytical reports (GC/MS) and regulatory compliance documents (e.g., REACH/TSCA status). These documents support safe handling, specifications and regulatory requirements.
How is D‑Limonene shipped and what packaging options are available?
D‑Limonene is transported as a flammable/combustible liquid—refer to the SDS for the exact UN number, hazard class and packing group applicable to your jurisdiction. Common packaging options include small bottles (100 mL–1 L) for lab use, drums (25–220 kg), IBCs/totes and bulk ISO tank shipments.
What materials are compatible or incompatible with D‑Limonene?
D‑Limonene is generally compatible with stainless steel, carbon steel and glass, but can swell or degrade many elastomers and plastics (for example natural rubber, certain nitriles, polystyrene and some coatings). Avoid contact with strong oxidizers and test seals, gaskets and coatings for compatibility before prolonged use.
What are the key technical specifications for D‑Limonene I should check?
Typical specifications include: molecular weight 136.24 g·mol⁻¹, formula C10H16, CAS 5989‑27‑5, appearance clear colorless to pale yellow liquid, density ~0.84 g·mL⁻¹ (20 °C), boiling point ~176 °C, refractive index ~1.471 (20 °C) and flash point ~47 °C (closed cup). Always confirm lot‑specific values on the COA.
Which industries and applications commonly use D‑Limonene?
D‑Limonene is used across industries including industrial cleaning and degreasing, coatings and adhesives, paint and graffiti removal, polymer and rubber processing, chemical synthesis and as a laboratory solvent and analytical standard. It is chosen where a terpene‑based hydrocarbon solvent is preferred for performance or environmental profile.
How can I purchase D‑Limonene and what availability or lead times should I expect?
D‑Limonene is sold in various grades and concentrations for lab and industrial use; suppliers typically offer samples and full documentation on request. Availability and lead times vary by quantity and grade but standard orders are commonly fulfilled within 1–3 weeks; contact your supplier for pricing, minimum order quantities and shipping options.
