Pumpkin seed oil (derived from the unhusked seeds of Cucurbita pepo L.) is a nutrient-dense botanical lipid renowned for its exceptional therapeutic, cosmeceutical, and dietary profile. Extracted using advanced cold-press mechanical expulsion (<45°C) without solvent residual risks, our oil retains maximum bioavailability of Delta-7-phytosterols, Essential Fatty Acids (EFAs), and lipophilic antioxidants.
As a leading manufacturer and exporter based in Jiangxi, China, Hairui Natural Plant guarantees strict adherence to international monograph requirements (EP/USP). Our pumpkin seed oil possesses a rich dichromatic deep-green to dark amber-red tone, characteristic of natural chlorophyll and carotenoid complexes, accompanied by a clean, nutty organoleptic profile.

Decoding why global enterprise buyers are accelerating wholesale pumpkin seed oil procurement.
Driven by clinical trials highlighting pumpkin seed oil's ability to inhibit 5-alpha reductase (blocking DHT conversion), cosmetics brands are incorporating bulk pumpkin seed oil into anti-hair loss scalp serums and growth oils, creating a surging search volume for wholesale refined and unrefined grades.
Nutraceutical manufacturers aggressively seek high-purity, standardized pumpkin seed oil softgels for Benign Prostatic Hyperplasia (BPH) management and lower urinary tract support. High concentrations of Delta-7-sterols are vital for product efficacy verification.
Non-comedogenic with a comedogenic rating of 2, rich in essential fatty acids (LA/OA), pumpkin seed oil restores lipid integrity, calms acneic inflammation, and provides anti-aging benefits, driving bulk demand among high-end clean skincare formulators.
