Lime Oil

🔹 What is Lime Oil

• Essential oil obtained from the peel of lime fruits (Citrus aurantifolia).
• Extracted by either:
• Cold-pressing the peel (retains more nutrients but is phototoxic), or
• Steam distillation (less phototoxic, commonly used in cosmetics).
• Known for its zesty, refreshing citrus aroma and wide use in aromatherapy, skincare, haircare, and natural cleaning.

🔹 Key Constituents

• Limonene (50–65%) → cleansing, uplifting scent.
• β-Pinene, γ-Terpinene → antimicrobial, energizing.
• Citral (Neral + Geranial) → sharp lemon-lime aroma, antibacterial.
• Flavonoids & coumarins (in cold-pressed oil) → antioxidants, but contribute to phototoxicity.

🔹 Cosmetic & Aromatherapy Benefits

1. Skin Care

• Cleansing & toning → great for oily and acne-prone skin.
• Brightening → helps improve dull complexion.
  Must be well diluted; cold-pressed lime oil may increase sun sensitivity (phototoxicity).

2. Hair Care

• Refreshes scalp, helps reduce dandruff.
• Adds shine and a citrusy freshness to shampoos.

3. Aromatherapy

• Mood booster → uplifting, reduces stress and fatigue.
• Air purifier → antibacterial and deodorizing properties.

4. Other Uses

• Soaps & candles → fresh citrus fragrance.
• Natural cleaning products → antimicrobial action and fresh scent.

🔹 Safety & Usage

• Dilution: typically 5%–2% in topical cosmetic products (3–12 drops per 30 mL carrier oil).
• Phototoxicity risk (cold-pressed type): avoid sun/UV exposure for 12–24 hours after application.
• Steam-distilled lime oil → safer for skincare, less risk of sun sensitivity.
• Store in a dark glass bottle, a cool place (lime oil oxidizes quickly).

🔹 Cosmetic Grade vs. Food Grade

• Cosmetic Grade → formulated for skincare, aromatherapy, and topical use.
• Food Grade → tested for ingestion, used as a flavoring agent in beverages and foods.
