Borage (Starflower)
B2B ingredient for professional formulation evaluation.
Borage oil is cold-pressed from the seeds of Borago officinalis (starflower), an annual herb with striking blue, star-shaped flowers native to the Mediterranean but now cultivated worldwide. Borage oil is the richest known plant source of gamma-linolenic acid (GLA), containing 20-26% GLA compared to 8-10% in evening primrose oil, making it the premier natural source of this important omega-6 fatty acid. Fresure's borage oil is produced from non-GMO seeds cultivated in Jilin Province, cold-pressed within 24 hours of harvest, lightly refined to remove sediment while preserving the delicate GLA content, and stabilized with natural vitamin E (mixed tocopherols) to prevent oxidation. Each batch is verified for GLA content by GC-FAME analysis.

Custom packaging and private labeling available upon request.
GLA-rich oils are highly susceptible to oxidation. Store in tightly sealed, nitrogen-flushed, full containers in a cool (ideally refrigerated at 2-8 deg C), dark place. Once opened, use promptly. Shelf life: 12-18 months under recommended refrigerated conditions; 6-12 months at room temperature. Monitor peroxide value (PV < 5 meq/kg maximum) as oxidation indicator.
Under recommended storage conditions — tightly sealed in a cool, dry environment away from direct sunlight — Borage Oil remains stable for 2 to 3 years. Monitor for any changes in aroma, color, or viscosity before use in production batches.
Borage Oil is cold pressing from the seeds of a plant in the Boraginaceae family.
Every shipment includes a Certificate of Analysis (COA) detailing the batch-specific chemical profile (GC/MS or GC-FID), physical parameters (specific gravity, refractive index, optical rotation), and organoleptic assessment. Material Safety Data Sheet (MSDS/SDS) is also provided. Additional documentation — including GC/MS chromatograms, pesticide residue analysis, heavy metal testing, and allergen statements — is available upon request.
