Carrier Oils (Base/Fixed Oils)
Carrier oils are plant-derived fatty oils (from nuts, seeds, kernels, or fruits) used to dilute concentrated essential oils (EOs) for safe topical use in aromatherapy, skincare, haircare, and massage. They “carry” EOs into the skin while providing their own nourishing benefits from fatty acids, vitamins (A, C, E), antioxidants, and other nutrients.
Unlike EOs, carrier oils are non-volatile, typically mild or lightly scented, and can be used alone. Opt for organic, unrefined, cold-pressed versions when possible. Always patch-test and store in cool, dark places (refrigerate some). Nut-derived oils should be avoided by those with nut allergies.
General Benefits and Uses
- Dilution & Safety: Essential oils are potent; typical adult dilutions are 1–5% (e.g., 6–30 drops EO per 6 tsp / 30 ml carrier). Lower for face, children, or sensitive skin.
- Skincare: Moisturize, soften, strengthen barrier, reduce inflammation/irritation (e.g., eczema, dryness), deliver antioxidants, support anti-aging.
- Haircare: Condition, reduce frizz/protein loss, add shine, soothe scalp, promote growth.
- Other: Massage (good glide), bath oils, DIY creams/soaps/balms, standalone moisturizers.
- Key Considerations: Match to skin/hair type. Blend carriers for custom textures/benefits. Add vitamin E as a natural preservative. Results vary; consult professionals for conditions, pregnancy, or children.
