In modern botanical extraction, the term "cold-pressed" refers to a mechanical extraction process where oils are obtained without the application of external heat or chemical solvents. For B2B procurement officers in the cosmetics, food, and pharmaceutical sectors, verifying that the extraction temperature remains strictly below 49°C (120°F) is vital. Maintaining low thermal thresholds prevents the degradation of volatile bioactive compounds, including essential fatty acids, tocopherols, polyphenols, and aromatic terpenes.
Unlike steam distillation, which utilizes high-temperature vapor to release volatile compounds, mechanical expeller or hydraulic pressing physically compresses the cellular matrix of the botanical raw material. While steam distillation is highly effective for isolating lightweight essential oils (such as lavender or geranium), cold-press extraction is the gold standard for carrier base oils (such as jojoba and rosehip). These base oils possess dense triglyceride profiles that would polymerize or oxidize under high thermal loads.
E-E-A-T Technical Insight: The structural integrity of Polyunsaturated Fatty Acids (PUFAs), such as Linoleic Acid (Omega-6) and Alpha-Linolenic Acid (Omega-3) in Rosehip or Black Seed oils, relies entirely on cold-pressed parameters. Exposure to temperatures exceeding 50°C triggers double-bond oxidation, resulting in high peroxide levels and shortened product shelf life.
The global demand for natural plant-derived ingredients is expanding rapidly, driven by consumer preferences for clean-label, synthetic-free formulations. B2B wholesale buyers are facing increasingly complex supply chain environments, demanding verified purity, consistent chemical profiles, and regulatory compliance.
Our sweet orange oil is a natural orange peel extract, derived from botanical resources without chemical residues. This provides unique ecological advantages, ensuring safety for surrounding environments. Sweet orange oil supports crop leaf respiration and photosynthesis, promoting overall crop health. Suitable for use as both an adjuvant and a primary pesticide, it delivers effective control against diverse insect pests and crop diseases, yielding measurable economic and ecological benefits.
Cold-pressed castor oil and jojoba oil serve as foundational ingredients for cosmetic formulations. Castor oil, rich in ricinoleic acid, supports hair follicle health and moisture retention. Used during washing or massaged directly, it enhances shine and conditions the scalp. Our pure jojoba oil mimics human sebum, making it a highly compatible, non-comedogenic carrier for skincare products, facial creams, and body lotions.
Cold-pressed evening primrose oil provides a rich source of Gamma-Linolenic Acid (GLA) alongside essential micronutrients like zinc and magnesium. Typically formulated into softgel capsules, it supports cardiovascular health and provides relief for premenstrual and menopausal discomfort. Maintaining cold-pressed parameters ensures these functional lipid profiles remain uncompromised.
Natural aromatic compounds interact directly with the olfactory pathway and limbic system, supporting cognitive and emotional balance. Pure lavender, geranium, and jasmine essential oils are widely utilized in diffusers, massage therapies, and functional soaps to promote relaxation, sleep, and stress reduction. These natural volatiles deliver consistent, high-potency sensory experiences.
A comprehensive raw material sourcing strategy requires a clear classification of botanical oil types. Hairui Natural Plant categorizes its commercial portfolio into three core technical segments:
Highly concentrated, volatile plant secondary metabolites typically extracted via steam distillation or precise cold compression. Sourced from eucalyptus, oregano, and peppermint, these ingredients serve cosmetic, pharmaceutical, and livestock feed applications.
Lipid-rich carrier oils extracted via cold-pressing from seeds and nuts. These oils act as stable, functional bases for high-potency essential oils. Many possess intrinsic therapeutic benefits, including essential fatty acids, phytosterols, and fat-soluble vitamins.
Solvent-free crystals, powders, or liquid separations isolated from raw botanical biomass. Sourced directly from our managed agricultural acreage, ensuring traceability and consistent active constituent concentrations.
Established in 2006 and located in the Jinggang Mountain High-Tech Development Zone, Ji’an, Jiangxi Province, Hairui Natural Plant is an industry-certified manufacturer of natural plant essential and carrier oils. Leveraging regional agricultural resources, our facilities represent an investment of RMB 50 million, covering 13,000 square meters. The plant is equipped with advanced analytical testing equipment and boasts a production capacity of 2,000 tons of natural essential oil annually.

At Hairui Natural Plant, raw material quality and process consistency are supported by our proprietary 9-Step QA/QC Protocol. This framework ensures each bulk shipment aligns with international cosmetic and pharmaceutical specifications.
The process begins with strict botanical seed selection, managing soil chemistry and crop placement across our 5000+ acre plantation. Post-harvest, seeds undergo mechanical cleaning and moisture checks. Mechanical pressing is continuously monitored to prevent thermal buildup.
Following primary extraction, oils undergo physical purification and filtration. In our laboratories, each batch is tested via Gas Chromatography (GC) to verify its chemical fingerprint. Only after verifying the active molecule concentrations, free fatty acid levels, and heavy metal limits is a Certificate of Analysis (COA) issued, authorizing the product for export.
Exporting to 56 countries and regions requires compliance with varied regulatory standards. Hairui Natural Plant maintains a dedicated global compliance team to support international distribution requirements.
