BLACK SEED OIL
THYMOQUINONE 2% · COLD PRESSED · FOOD & COSMETIC GRADE
A cold-pressed vegetable oil from the seeds of Nigella sativa L., standardized to Thymoquinone 2% and verified by GC lot by lot. Presented as a brown to amber transparent liquid with the characteristic herbal aroma of genuine black seed oil — 100% pure oil, no additives. Supplied in 25 kg and 50 kg drums, or customized to your specification. Sourced from high-thymoquinone seed lots: most cold-pressed oil on the market sits at 0.5–1%, this grade is selected at the top of what cold pressing can reach.
TECHNICAL SPECIFICATIONS
Specifications above are the release limits for this grade; the measured value for each production batch is reported on its batch COA.

Quality control: Each batch can be tested for reference before bulk order.
FUNCTIONAL ROLES
1. Oil Phase for Capsules and Liquid Formats
A single-ingredient oil that fills directly as a softgel or liquid supplement medium, or blends into an oil-phase premix — no carrier oil needed unless the formulation calls for one.
2. Emollient Base for Topical Systems
Miscible with other vegetable and carrier oils, so it drops into facial, body and hair oil systems as the oil phase, and disperses into emulsified cream and lotion bases with a standard emulsifier set.
3. Characteristic Aroma and Colour Contributor
The warm, pungent herbal note and amber tone come from the seed itself and carry into the finished product — useful where the formulation reads on the label as a single, recognisable oil.
INDUSTRIAL APPLICATIONS
1. Soft Capsules & Liquid Supplements
Used as the fill oil in softgel capsules and as a liquid supplement base, at up to 100% of the fill where the oil carries the label on its own.
2. Facial, Body & Hair Oils
Formulated into topical oil systems at typical levels of 5–20% in facial and body oils and 10–30% in hair and scalp blends.
3. Soap, Lotion, Cream & Shampoo
Added to personal-care bases as the oil phase, including bar soap, lotions, creams and shampoo systems where a labelled single seed oil is wanted.
4. Functional Food & Nutritional Formulations
Blended into functional food and nutritional formulations at typical inclusion rates of 1–5%, where the oil contributes flavour as well as lipid content.

TECHNICAL FAQ
Q1: Why is 2% thymoquinone significant for a cold-pressed oil?
A: Cold-pressed black seed oil typically carries 0.5–1% thymoquinone, and only selected seed lots reach the 1–2% band. Holding 2% without refining means the buyer gets a higher active load per kilogram of oil, which reduces the fill weight needed in a capsule or a topical formula.
Q2: How is the thymoquinone figure verified?
A: By gas chromatography on each production lot, reported on the batch COA together with acid value, peroxide value, iodine value and saponification value. A batch sample can be sent ahead of a bulk order so your own laboratory can confirm the figures first.
Q3: Is the oil pure, or is the thymoquinone level raised by adding isolate?
A: The oil is 100% pure, with no additives, carriers or added flavour. The 2% figure is reached by selecting high-thymoquinone seed lots rather than by dosing in an isolate — the specification and the batch COA describe the oil as pressed from Nigella sativa seed only.
Q4: What packaging and minimum order do you supply?
A: Orders start at 1 kg. Bulk formats are 25 kg and 50 kg drums, with custom pack sizes available; samples are supplied in 100 g or 500 g bottles. Stored sealed, cool and away from light, shelf life is 2 years / 24 months.
