Product Overview
D-Limonene 94% is a naturally derived terpene solvent sourced from citrus peels. It is a clear, colorless, mobile liquid with a bright citrus odor — immediately recognizable when you crack the cap. Designated Food Grade, this product is offered for food-flavoring operations, industrial degreaser formulations, botanical extraction, and fragrance compounding. Alliance Chemical supplies it in sizes from 1 Qt bottles for bench-scale work through 330 Gal totes for continuous production lines.
Why This Concentration
At 94%, this D-Limonene delivers a high active-solvent load straight from the container. For degreaser and cleaning formulations, that concentration means fewer dilution steps and stronger grease-cutting performance per unit volume. For food-flavoring work, a concentrated starting material lets formulators dial in exact citrus intensity without carrying excess carrier. Extraction operations benefit from a solvent that pulls target compounds efficiently while remaining compatible with food-grade process requirements.
The Food Grade designation signals to a procurement team that this product was sourced and handled for food-adjacent workflows — flavoring, food-contact surface cleaning, and extraction where residual solvent matters. Buyers whose processes do not require that designation may find a technical or industrial grade more cost-effective for straight degreasing and parts cleaning.
Chemical Profile
D-Limonene (CAS 5989-27-5) is a monocyclic monoterpene with the molecular formula C10H16 and a molecular weight of 136.23 g/mol. It presents as a clear, colorless, mobile liquid with a pleasant lemon-like citrus odor. Its density is 0.8411 at 68 °F — lighter than water, so it floats on aqueous layers during separation steps. Solubility in water is low, less than 1 mg/mL at 67.1 °F, which is why it partitions cleanly in liquid–liquid extraction setups. Vapor pressure rises from 1 mmHg at 57 °F to 5 mmHg at 104.7 °F and 10 mmHg at 128.8 °F, so ventilation requirements increase noticeably in warm environments. Operators working with open containers in summer heat should plan accordingly.
Industrial Applications
D-Limonene's combination of solvent strength, citrus origin, and Food Grade handling opens it to several industries.
-
Industrial Cleaning and Degreasing. D-Limonene is a proven solvent in degreaser formulations, cutting through oils, greases, and adhesive residues on metal parts, shop floors, and processing equipment. Its citrus odor is a practical advantage over petroleum-based alternatives in enclosed or occupied workspaces.
-
Food Flavoring. Used as a natural flavoring agent in beverages, confections, and baked goods where a citrus character is the target profile. The 94% concentration gives formulators precise control over flavor intensity at the batch level.
-
Botanical and Essential Oil Extraction. Serves as an extraction solvent for isolating active compounds and essential oils from plant material — particularly in operations where the residual solvent must be food-compatible.
-
Fragrance Compounding. A standard building block in perfumes, personal care products, and household scent formulations for its bright citrus top note and consistent character.
-
Agricultural Formulations. Incorporated into natural pesticide blends as an active or carrier component in pest-control products where a citrus-derived solvent is preferred over synthetics.
Handling & Storage
D-Limonene 94% carries a Danger signal word (per the product's GHS classification). Operators should be aware of the following governed hazard statements:
- H226 — Flammable liquid and vapor (per the product's GHS classification)
- H304 — May be fatal if swallowed and enters airways (per the product's GHS classification)
- H315 — Causes skin irritation (per the product's GHS classification)
- H317 — May cause an allergic skin reaction (per the product's GHS classification)
- H410 — Very toxic to aquatic life with long-lasting effects (per the product's GHS classification)
Wear chemical-resistant gloves and safety goggles when handling. In areas with limited ventilation, use respiratory protection rated for organic vapors. This is a Class 3 flammable liquid — store in a cool, dry location away from direct sunlight, heat sources, and open flame. Use HDPE or glass containers. Avoid contact with strong oxidizing agents and concentrated acids. Keep containers sealed when not in use to limit vapor accumulation and preserve product integrity. Given the aquatic toxicity profile (H410), prevent any release to drains, storm sewers, or waterways.
