Traditional solvent extraction processes rely heavily on organic hydrocarbons (e.g., hexane). While effective for high-yield applications, these processes introduce the risk of residual solvents and heat-induced thermal degradation of volatile phytochemical compounds. Consequently, industries are turning to mechanical cold-pressed technology to meet clean-label, bio-intact component requirements.
At the center of cold-pressed extraction is the management of thermal and mechanical stress. Standard mechanical expellers subject materials to extreme frictional pressure, causing internal temperatures to exceed critical thresholds. For thermolabile compounds, such as unsaturated fatty acids, active enzymes, and volatile terpenes, temperatures above 50°C lead to accelerated oxidation, cis-trans isomerization, and partial denaturation. To prevent this, specialized manufacturers implement temperature-controlled, continuous water-cooled expeller systems. By keeping temperatures strictly below 49°C (120°F), we preserve the raw botanical profiles, natural antioxidants (tocopherols, tocotrienols), and phytosterols essential for premium consumer formulations.
Protects sensitive bio-actives (e.g., GLA in evening primrose oil, d-limonene in sweet orange oil) from heat degradation.
Guarantees zero chemical solvent residues (hexane-free), matching clean label compliance frameworks globally.
Maintains natural color, odor, and nutritional profiles, avoiding the necessity of post-extraction refining.
While both cold compression (cold pressing) and steam distillation are chemical-free extraction methods, they serve different raw material profiles. Cold compression is primarily utilized for citrus fruits (where essential oils are housed within the flavedo of the peel) and lipid-rich seeds (base/carrier oils). Mechanical pressure ruptures the oil sacs, and a subsequent centrifugal process separates the oil from the aqueous phase. Conversely, steam distillation uses high-temperature steam to volatilize compounds from herbaceous matter, roots, and bark, condensing them into essential oils. Our facility leverages both methods to support comprehensive B2B formulation demands.
Optimized plant lipid derivatives categorised by extraction methodology, chemical attributes, and commercial application.
Essential oils are usually extracted by steam distillation or cold compression. The raw materials used in the production of essential oils, food, and cosmetics are the second largest category of our products, such as camellia oil, eucalyptus oil, oregano oil, and peppermint oil. Hairui Natural Plant selects high-quality raw materials with high standards, strictly controls and supervises the whole production and extraction process, and adopts strict inspection standards to guarantee premium-grade oils.

Base oil, also known as medium oil or carrier oil, is usually extracted by cold compression. Single essential oils cannot be rubbed directly on the skin; they must be diluted in a carrier oil before they can be widely used on body skin. Many carrier oils possess inherent medical and dermatological properties. We extract a wide variety of vegetable carrier oils matching international pharmacopoeias.

Herbal extracts are often isolated through cold-precipitation from essential oils or solvent-free concentration. High-quality products come from high-quality raw materials. We have a 5,000+ acre self-owned raw material production base, where the entire process from seed selection, seedling raising, planting, and harvesting is supervised and controlled, ensuring timely supply and quality.

Organic certification, pesticide-free verification, and fully traceable supply chains have transitioned from premium options to baseline requirements for mass-market distribution. In response, global manufacturers are updating their vendor selection criteria to require comprehensive documentation, including Gas Chromatography-Mass Spectrometry (GC-MS) testing, allergen reporting, and heavy metal analyses.
Sourcing bulk raw materials requires reliable capacity. Disruptions from climate variation, shipping challenges, and raw material volatility present risks for global brands. As a result, companies are moving away from spot purchasing toward structured annual supply agreements with manufacturers that own agricultural acreage. Direct farm ownership stabilizes input pricing, ensures product consistency, and prevents contamination from third-party consolidation points.
Furthermore, ESG (Environmental, Social, and Governance) targets require zero-waste extraction models. Modern cold-pressed facilities repurpose solid waste cake (pomace) into animal feed, bio-fertilizers, or secondary powder extracts. This circular model minimizes environmental impact and optimizes manufacturing yield, lowering costs for volume buyers.
How our cold pressed oils and botanical extracts solve formulation, regulatory, and performance challenges across four core industrial sectors.
Natural plant oils play a key role in bio-pesticide and adjuvant formulations. For instance, cold-pressed sweet orange oil contains d-limonene, a natural orange peel extract that provides insecticidal properties with minimal ecological residue. Orange oil disrupts the waxy protective cuticles of soft-bodied insects, resulting in rapid knockdown effects while promoting crop respiration and photosynthesis. Similarly, neem oil, rich in azadirachtin, acts as a systemic growth regulator and anti-feedant, helping prevent insect pest resistance when combined with traditional chemical agents.
In personal care, cold-pressed base lipids are valued for their skin-barrier compatibility and fatty acid profiles. Castor oil, rich in ricinoleic acid, serves as a natural humectant and antimicrobial agent in hair care, moisturizing the scalp and supporting hair growth. Macadamia nut oil contains high levels of palmitoleic acid (Omega-7), which mimics human sebum to restore lipid levels in dry or aging skin. Cold-pressed rosehip oil provides essential fatty acids (Omega-3 and Omega-6) along with trans-retinoic acid, supporting skin regeneration and anti-aging formulations.
For dietary supplements, cold pressed extraction preserves active nutritional molecules. Evening primrose oil contains 70% linoleic acid (LA) and 7-10% gamma-linolenic acid (GLA), which support hormone balance, cardiovascular function, and joint health. Because high heat can degrade these essential fatty acids, cold-pressed evening primrose oil is ideal for softgel encapsulation. Preserving the natural tocopherols in the oil also improves oxidative stability and extends shelf life.
Aromatherapy relies on high-purity essential oils to stimulate olfactory receptors connected to the limbic system, which regulates emotions, memory, and autonomic functions. Our premium essential oils, including lavender, eucalyptus, tea tree, and cinnamon, are processed without synthetic diluents or chemical solvents. This preserves the natural terpene profiles required for clean diffusion, commercial home-fragrance lines, and therapeutic applications.
Our extraction technology roadmap focuses on efficiency, purity, and environmental responsibility. A key development is the integration of inert gas blanketing (typically using nitrogen) throughout the milling and pressing phases. Oxygen exposure during mechanical cell disruption can lead to early lipid oxidation. Working under an inert atmosphere protects sensitive chemical bonds, yielding lower peroxide values and longer shelf life without synthetic preservatives.
Additionally, we are exploring ultrasonic-assisted extraction (UAE) to pre-treat seeds. This method uses acoustic cavitation to micro-fracture cell walls, allowing oil release at lower mechanical pressures. This reduces energy consumption and limits friction-induced heat generation during processing.
For traceability, we are implementing IoT sensors on our expellers to track temperature, pressure, and flow rates in real time. This data is logged to create a digital batch record, providing B2B buyers with documented quality control from raw seed to delivered product.
