Explore our premium factory-direct natural oils and cosmetic raw materials sourced globally under rigorous laboratory controls.
Camphor crystals (CAS No. 76-22-2) represent a foundational chemical compound utilized extensively across global pharmaceutical, industrial, agricultural, and cosmetic manufacturing sectors. B2B procurement of camphor crystals requires strict adherence to physical-chemical parameters. As a volatile, crystalline solid with a characteristic penetrating odor, camphor crystals are primarily sourced as natural D-camphor (extracted from Cinnamomum camphora) or synthetic DL-camphor (synthesized from pinene).
Global procurement departments prioritize three pillars: chemical purity, supply continuity, and regulatory compliance. For pharmaceutical applications, the crystalline structure must exhibit a purity level of ≥96% to ≥99% (conforming to USP/EP pharmacopeias). Our state-of-the-art refinery facilities optimize crystallization techniques to control grain size distribution, guaranteeing fast dissolution rates and uniform melting points crucial for localized topical analgesics, vapor rubs, and industrial polymers.
"B2B camphor procurement is transitioning from a commodity transaction to a specialized sourcing model, where trace residue management and logistics safety certificates (such as the UN 2717 Class 4.1 Flammable Solid declarations) dictate the choice of refinery partners."
Moreover, international raw material price volatility forces purchasing managers to secure direct partnerships with factory sources. By integrating the plantation sourcing of crude camphor oil with large-scale crystallization machinery, our factory stabilizes supply lines against macroeconomic shocks. We provide global clients with transparent pricing, customized packaging formats (from 25kg fiber drums to bulk big-bags), and strict moisture control to avoid product clumping during ocean transit.
Our camphor crystal production utilizes two distinct pathways to cater to varying industrial demands. Below is the technical breakdown outlining the difference between Natural D-Camphor Crystals and Synthetic DL-Camphor Crystals manufactured at our facility:

| Optical Rotation [α]D20 | +41° to +43° (c=10 in ethanol) | Optically Inactive (±0.5°) |
| Non-Volatile Residue | ≤ 0.05% | ≤ 0.1% |
| Heavy Metals (Pb, As) | ≤ 5 ppm | ≤ 10 ppm |
| Primary Applications | Pharmaceutical formulations, high-end skincare, traditional medicine | Industrial plasticizers, moth repellents, paint additives, varnishes |
Technical Route 1 (Natural): Raw foliage and wood fractions of Cinnamomum camphora undergo high-pressure steam distillation. The resulting essential oil contains fractions of cineole, camphor, and safrole. Through multi-stage vacuum fractional distillation, we isolate the camphor fraction. Centrifugal separation and subsequent recrystallization from organic solvents yield pure D-camphor crystals.
Technical Route 2 (Synthetic): Alpha-pinene, extracted from natural turpentine, is isomerized to camphene. Camphene is esterified to isobornyl acetate and subsequently saponified to isoborneol. The final catalytic oxidation of isoborneol delivers high-purity DL-camphor crystals, which are subsequently sublimed for crystal structure alignment.

Within the pharmaceutical sector, camphor crystals function as a critical active pharmaceutical ingredient (API) in counter-irritant ointments, topical gels, and local anesthetics. Upon skin application, camphor stimulates nerve endings sensitive to cold and warmth, producing a cooling or heating sensation that effectively masks pain pathways. Our pharmaceutical-grade crystals possess extremely low levels of organic impurities, ensuring stable compounding in formulations alongside menthol and methyl salicylate.
For pest control and preservation, the sublimation characteristics of camphor crystals offer continuous, self-dispersing protection. The crystalline structure vaporizes slowly at room temperature, releasing aromatic fumes that disrupt the respiration of target pests. By producing customized grain sizes, we help manufacturers modulate this sublimation rate, maximizing the shelf-life and efficacy of mothballs, wardrobe sanitizers, and agricultural fumigants.
"The future of camphor chemistry lies in green catalytic routes and synthetic biology. Our engineering team is currently researching bio-catalytic pathways to convert renewable agricultural waste into camphor precursors, reducing the industrial carbon footprint by 40%."

Essential oil usually extracted from the flowers, leaves, seeds, roots, bark, fruits and other parts of the plants, and extracted by steam distillation, cold compression, fat absorption or solvent extraction. Comes out, with a high concentration of aroma and volatility. It can be used in many fields.
For example, the sweet orange oil is a natural orange peel extract, derived from nature, without any residual risk, and has unique advantages of being safe to the ecological environment. orange oil can promote crop leaf respiration and photosynthesis, and promote crop growth. This product can not only be used as an adjuvant, but also can be used alone as a pesticide. It has a good control effect on various diseases and insect pests, a wider range of applications, and more obvious economic benefits.
For example the castor oil can promote the growth of hair. When washing hair, use a little castor oil and then massage the hair, which is conducive to the absorption of castor oil. In addition, it can also moisturize the hair and make the hair shiny. At the same time, castor oil can also prevents and treats infections of the scalp.
For example, the evening primrose oil main components: r-linolenic acid, magnesium, zinc, copper, vitamin C, E, B6, B5. Among them, the most abundant is about 70% linoleic acid (Linoleic Acid, referred to as LA) and about 7-10% GLA. It can be made into capsules and taken orally to treat cardiovascular diseases, premenstrual syndrome, and menopausal syndrome.
In 1926, Gaitefussey of France burned his finger in an experiment, and he immediately treated the wound with lavender, and the effect was very good. In 1928, he proposed the concept of "aromatherapy" at a scientific conference. For example the essential oil can adjust emotion. The aromatic molecules of essential oils travel through the nasal cavity into the olfactory area of the brain and eventually reach the limbic system, regulating mental state.
To maintain authoritative supply chains, our industrial testing laboratory uses advanced gas chromatography coupled with mass spectrometry (GC-MS) alongside high-performance liquid chromatography (HPLC) to verify the isomeric purity of camphor batches. Every production lot is systematically tested for moisture content, heavy metal trace elements, and acid value. Our facility adheres to Good Manufacturing Practices (GMP) and is accredited with major global standardization certifications.
For pharmaceutical formulations, we verify optical activity and melting temperature ranges to prevent the dispatch of batches displaying structural deviations. Additionally, we provide comprehensive documentation support, including Certificates of Analysis (COA), Safety Data Sheets (SDS), Technical Data Sheets (TDS), and regulatory dossiers essential for national environmental agencies.
Crucial information regarding purity standards, logistics, custom formulations, and safety regulations.
Natural D-camphor is optically active (+41° to +43°) and extracted from Cinnamomum camphora tree wood and leaves. It is preferred for pharmaceutical applications and traditional medicine due to its natural origin. Synthetic DL-camphor is an optically inactive racemic mixture produced synthetically from turpentine-derived pinene, offering identical cooling efficacy at a more competitive cost structure, making it ideal for industrial products, plasticizers, and repellents.
Since camphor sublimates slowly at room temperature, we package our crystals in hermetically sealed food-grade polyethylene inner liners, which are then placed within robust fiber drums or multi-wall corrugated boxes (typically 25kg net weight). For tropical destinations, we offer foil-barrier packaging and climate-controlled container shipping to prevent clumping and evaporation.
