Onion, Essential Oil

Onion, Essential Oil is a pure aromatic extract obtained through steam distillation (or cold expression, where applicable) of the plant's botanical material. O&3 sources its essential oils from specialist growers and distillers worldwide, selecting origins that deliver the most consistent quality and authentic chemical profile.

Onion, Essential Oil carries a characteristic aroma profile that makes it a popular choice in perfumery, aromatherapy, and functional cosmetics. It is widely valued for its potential antimicrobial, antioxidant, and skin-conditioning properties, though specific activity depends on the chemotype and batch chemistry.

Essential oils should always be diluted in a suitable carrier oil before applying to skin. A typical usage level is 0.5–2% in leave-on products and up to 3–4% in rinse-off formulations. Always perform a patch test before use, and consult current IFRA guidelines for Onion specifically, as maximum usage levels vary by application category.

Onion essential oil can be diluted in a wide range of carrier oils. Lightweight, easily absorbed options such as Jojoba Golden Oil, Fractionated Coconut Oil, or Sweet Almond Oil are popular choices. For richer formulations, Argan Oil or Rosehip Seed Oil work well.

Onion is a versatile blending component that works harmoniously with complementary botanical extracts. Citrus oils, florals, woods, and resins are common blending partners depending on the desired fragrance direction. We recommend small-scale trials to find your ideal ratio before scaling up.

Onion, Essential Oil is suitable for a wide range of applications including facial serums, body oils, massage blends, hair care products, candles, and room sprays. It can also be incorporated into solid bars, balms, and creams where a small percentage of active essential oil is desirable.
