Explore our factory-direct bulk portfolio of pure carrier oils, essential oils, and plant extracts meticulously refined for global cosmetic, pharmaceutical, and nutraceutical applications.
In the contemporary landscape of global botanical extraction, Natural Pumpkin Seed Oil (Cucurbita pepo L.) has transitioned from a localized traditional therapeutic agent to a premier, high-value raw material demanded by pharmaceutical, cosmetic, and functional food conglomerates. Fueled by escalating consumer awareness surrounding clean-label nutrition, preventative prostate health remedies, and bio-based skin lipid barriers, global procurement volumes for bulk cold-pressed pumpkin seed oil have witnessed an unprecedented compound annual growth rate (CAGR) of 8.4% entering 2025.
As international regulatory bodies enforce stricter limits on residual solvents and oxidative degradation products, global enterprise buyers are rapidly shifting sourcing preferences away from traditional chemically refined seed oils toward mechanically cold-pressed, unrefined, and standardized lipid extracts. Natural pumpkin seed oil is structurally unique due to its dense concentration of essential fatty acids (specifically Linoleic Acid Omega-6 and Oleic Acid Omega-9), bioactive phytosterols (such as Δ-7-sterols), tocopherols (α- and γ-tocopherol), carotenoids, and bioavailable zinc.
Clinical validation of Δ-7-sterols in blocking dihydrotestosterone (DHT) binding to androgen receptors has positioned cold-pressed pumpkin seed oil as a cornerstone ingredient in high-potency softgel capsules aimed at Benign Prostatic Hyperplasia (BPH) management and androgenic alopecia therapy.
Cosmetic formulators across Europe and North America are integrating high-purity pumpkin seed oil into facial serums and barrier repair creams. Its natural balance of linoleic acid restores compromised stratum corneum lipids without clogging pores, leveraging a zero-comedogenic risk profile.
Global regulatory oversight (EU REACH, US FDA FSMA) has heavily penalized hexane-extracted oils. B2B purchasing agents now mandate single-press mechanical extraction conducted strictly under low-temperature parameters (< 45°C) to preserve active natural compounds.
As global supply chains face structural realignments, China’s advanced botanical extraction infrastructure—represented by state-of-the-art facilities like Jiangxi Hairui Natural Plant Co., Ltd.—delivers an unprecedented benchmark of supply stability, chemical consistency, and cost-competitiveness. Situated in the Jinggang Mountain High-Tech Development Zone, Hairui integrates localized raw material cultivation with Industry 4.0 automation.
By operating over 5,000 acres of standardized agricultural base holdings and strategic contract farming networks, Hairui maintains 100% seed-to-oil traceability. Pumpkin seeds undergo optical sorting to eliminate damaged kernels prior to cold pressing, minimizing peroxide values right at the source.
Utilizing automated PLC-controlled continuous cold-pressing machinery, processing temperatures are rigidly contained below 42°C. This ensures zero thermal degradation of heat-sensitive Vitamin E tocopherols, retaining the vibrant deep green-to-dark red dichromatic optical spectrum characteristic of unrefined pumpkin oil.
Supported by a 50 Million RMB infrastructure investment, our testing laboratory operates Gas Chromatography-Mass Spectrometry (GC-MS), High-Performance Liquid Chromatography (HPLC), and Atomic Absorption Spectroscopy to guarantee zero heavy metal contamination and pesticide compliance.
For B2B buyers, cosmetic scientists, and brand procurement managers, ensuring batch-to-batch consistency is non-negotiable. Below is the analytical standard for Hairui’s Wholesale Cold-Pressed Natural Pumpkin Seed Oil:

Natural Pumpkin Seed Oil’s versatility spans multiple global manufacturing sectors. Below are established B2B commercial application vectors:
Used as an active carrier oil in scalp serums (recommended dosage 3%–10%). It inhibits 5-alpha reductase locally, reducing scalp DHT levels to promote hair follicle regeneration. Excellent in anti-aging night oils for restoring cellular elasticity.
Formulated into 500mg and 1000mg dietary softgels targeting urological wellness. Nitrogen blanketing during processing preserves active phytosterols and prevents in-capsule lipid oxidation.
Utilized as a high-end finishing oil in artisanal culinary blends and functional nutritional salad dressings, providing a rich signature dark hue and robust nutty flavor profile without chemical additives.
Founded in 2006, Jiangxi Hairui Natural Plant Co., Ltd. is located in Jinggang Mountain High-Tech Development Zone, Ji'an. With a total investment of RMB 50 million, our 13,000 square meter facility produces over 2,000 tons of pure botanical essential and base oils annually.
Extracted primarily via steam distillation or cold compression. Includes premium camellia oil, eucalyptus oil, oregano oil, and peppermint oil used as raw materials in pharmaceuticals, food, and cosmetic formulations.

Addressing critical technical, quality control, and global logistics queries for commercial pumpkin seed oil procurement.
Hairui utilizes automated, hydraulic cold-pressing technology operated under strict low-temperature conditions (< 45°C). We refrain from using chemical extraction solvents such as hexane. This physical mechanical extraction technique retains 100% of bioactive phytosterols, carotenoids, and native tocopherols while maintaining a low peroxide value (≤ 5.0 meq O₂/kg).
Pumpkin seed oil contains elevated concentrations of specific Δ-7-sterols (such as Δ-7-avenasterol and spinasterol). Clinical research indicates these phytosterols competitively inhibit the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). Lowering DHT levels aids in reducing prostate tissue swelling and mitigating hair follicle miniaturization in androgenic alopecia.
We accommodate diverse commercial purchasing scales. Standard export packaging includes 25kg plastic drums, 50kg aluminum/steel drums, 180kg heavy-duty steel drums, and 1,000kg IBC totes for bulk industrial users. Sample quantities (100g – 1kg) are available upon request for lab R&D testing prior to bulk contract execution.
When stored in original unopened nitrogen-flushed containers in a cool (15°C–25°C), dry environment away from direct sunlight, the shelf life is 24 months. For extended bulk storage, nitrogen head-spacing is recommended to minimize oxygen exposure and maintain peroxide value stability.
Yes. Every shipment is dispatched with a batch-specific Certificate of Analysis detailing physical parameters, acid values, peroxide values, GC-MS fatty acid spectrums, and heavy metal limits.
