NIGELLA SATIVA SEED OIL.

Valuable CAS 90064-32-7 / PERFUMING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

Nigella Sativa Seed Oil, also known as Black Seed Oil, is a versatile botanical extract celebrated for its dermatological benefits. Rich in active compounds, it effectively mitigates inflammation, provides robust antioxidant protection, and exhibits antimicrobial properties. This ingredient is particularly beneficial for addressing acne, reducing eczema symptoms, and enhancing overall skin barrier health.

Summary

Antioxidant Anti-inflammatory Emollient Moisturizer Antimicrobial

Science

Mechanism of Action

The primary mechanism of Nigella Sativa Seed Oil is attributed to thymoquinone, its key active component, which delivers potent anti-inflammatory effects by downregulating pro-inflammatory cytokines (e.g., interleukin-1β, 2, and 6) and inhibiting cyclooxygenase (COX). It functions as a powerful antioxidant, safeguarding skin from oxidative damage and free radicals by boosting antioxidant enzyme activity (e.g., SOD, GPx, catalase). Its high content of essential fatty acids, including 50-60% linoleic acid and 20% oleic acid, nourishes the skin, strengthens the lipid barrier, and promotes hydration by integrating with ceramides. Furthermore, it accelerates wound healing through stimulated tissue growth and collagen synthesis, potentially balances sebum production, and may assist in regulating melanin dispersion for pigmentation concerns.

Key findings

  1. 01 Reduced acne severity by 78% in a human study when a topical gel with black seed extract was applied twice daily for 60 days.
  2. 02 Demonstrated efficacy comparable to a prescription steroid cream (betamethasone) and a lanolin-based emollient (Eucerin) for hand eczema, when applied twice daily over 4 weeks in an ointment formulation.
  3. 03 Decreased skin inflammation and the total number of lesions in acne patients, yielding results comparable to benzoyl peroxide in a lotion formulation.
  4. 04 A balm containing 10% black seed oil significantly reduced inflammation (edema) in rats within a few hours.
  5. 05 Enhanced the healing process of open wounds reliably in an animal study when formulated as a 50% oil cream.

Stability

Thymoquinone, the primary bioactive compound, can experience rapid degradation in solution. The pH values of emulsions containing this ingredient may also degrade over time.

Conflicts

  • Not recommended for use on mucous membranes or the delicate eye-contour area.
  • High concentrations or undiluted application can lead to contact dermatitis, particularly for sensitive skin; dilution (e.g., 5-10% in a carrier oil) is generally advised to mitigate sensitizing potential.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

Generally considered safe for topical use in skin and hair care, though moderation and patch testing are crucial, especially for sensitive individuals. While rare, acute contact dermatitis, including severe polymorphic lesions, has been reported with topical application, often linked to thymoquinone and undiluted use. The FDA recognizes N. sativa extract as safe, and it does not appear to be photosensitizing.
