Pure Onion Essential Oil 100ml (Allium cepa) - Steam Distilled

In this review the Deve Herbes Pure Onion Essential Oil is evaluated for people seeking a concentrated, single-ingredient oil for aromatherapy, cosmetic blends, or focused topical blends when diluted. The bottom line: this 100ml bottle delivers a pure, steam-distilled Allium cepa oil in a high quality amber glass bottle with a glass dropper, which preserves potency and offers good value for anyone who needs an undiluted, therapeutic grade onion essential oil for custom blends or aromatherapy use.

Key Features

• Pure steam distilled: Extracted by steam distillation to retain the natural profile of Allium cepa without solvents or alcohol for authentic aromatic use.
• Large 100ml bottle: The 3.38 oz amber glass bottle with glass dropper preserves potency and is convenient for repeat dilution and blending.
• Single ingredient: Undiluted and non-deodorized, suitable for formulators who want complete control over carrier selection and concentration.
• Skin and hair guidance: The included dilution guidelines (1% to 5% for routine use, higher for acute care) make it easier to safely incorporate into topical blends when mixed with a carrier oil.
• Clean formulation: Vegan, cruelty-free, solvent-free, paraben free and without additives or preservatives for those preferring a simple ingredient list.

Who It's For

Deve Herbes Pure Onion Essential Oil is best for aromatherapists, DIY skincare and haircare formulators, and anyone who blends therapeutic oils and needs a sizable, undiluted Allium cepa oil in a stable amber bottle. It is useful for creating neuropathy or massage blends when diluted, and for home fragrance or cleaning product recipes that call for a bold botanical note.

Those who should look elsewhere include users wanting a ready-to-use, pre-diluted topical oil or anyone sensitive to strong, sweet or thick aromatic profiles; the oil must be diluted before skin use and some customers noted variable sweetness and a heavier texture compared with lighter essential oils.

Pros & Cons
