- Petitgrain = lá + cành nhỏ của cùng cây cam đắng (Citrus x aurantium) — phần thực vật khác hoàn toàn với Neroli (hoa) và Bitter Orange (vỏ quả). Co-product family của một cây.
- Hazards: None known. Contraindications: None known. Non-phototoxic (Ford 1992 mice + swine) — không như vỏ bitter orange (phototoxic 1.25%).
- 2 chemotype thương mại: Bigarade (higher-grade, linalyl acetate 51–71%) vs Paraguayan (cheaper, linalyl acetate 47.4–58%). Bigarade thường bị adulterated bởi Paraguayan; Paraguayan tự nó cũng bị synthesize.
- Linalyl acetate + linalool chiếm 70–95% → ester-alcohol dominant; ester cung cấp relaxing profile tương tự lavender nhưng tone clearer/green hơn.
- Framework default 5% dermal (không có T&Y restriction). Linalool peroxide cảnh báo: storage + antioxidant recommended.

⭐⭐⭐☆☆ — Imported; widely available under name "tinh dầu lá chanh (petitgrain)" at Vietnamese aromatherapy suppliers; Paraguay-origin most common. Price: ~150,000–400,000 VND / 10 ml at mid-market; specialist organic grade higher. NOTE: Vietnamese market commonly mislabels this as "tinh dầu lá chanh" (lime/lemon leaf oil) — verify Latin name on label.
Fresh, woody, floral-acetate, green, slightly bitter-citrus, clean, dry
Tươi mát – xanh lá – hoa nhẹ – gỗ khô – sạch thoáng — ít ngọt hơn neroli, ít nồng hơn hoa cam absolute
2–4 hours (skin); 6–10 hours on fabric; Paraguay-origin has higher tenacity than French-origin
Usable but not a primary choice; linalool offers mild skin support; combine with rich carrier (sweet almond, argan); ensure hydration focus elsewhere
Excellent — sebum-regulating, antimicrobial against acne bacteria, non-comedogenic; use 1% in jojoba or grapeseed toner/serum
Anti-inflammatory linalool + antispasmodic esters soothing; use ≤0.5% in hemp seed or evening primrose carrier during remission; avoid active flare
Antioxidant + cell-renewing linalool beneficial; combine with rosehip carrier; use in evening blend at 0.5–1%; less cytophylactic than rose or neroli but useful
Patch test; linalool can cause sensitisation at >2%; stay ≤0.5% for sensitive skin; avoid if linalool-allergic (EU 26)
Top recommendation — balances T-zone oiliness while acceptable on dry zones; jojoba-based toner at 0.5% ideal

Pha Chế & Hòa Hợp
Linalool modulates GABA-A receptors reducing CNS excitation; linalyl acetate hydrolysed to linalool in vivo adding bioavailable anxiolytic action; Citrus aurantium EO (petitgrain/leaf fraction) demonstrated significant anxiolytic effect in EPM test and reduced anxiety in clinical public-speaking model via nebulisation.

High ester content (linalyl acetate 40–72%) acts directly on smooth and striated muscle, reducing spasm; clinically relevant for IBS-type cramping, muscular tension, and dysmenorrhoea when applied topically.

- x **Maximum reasonable dermal for facial skincare:** **1%** (Tisserand & Young general guidance for moderately sensitive EOs)

- x *Pregnancy & Breastfeeding (Thai kỳ):**
- x T1 (tam cá nguyệt 1): **CAUTION** — avoid high doses; low-level diffusion (2 drops, large room) considered low risk; avoid therapeutic topical application
- x T2: **CAUTION** — 0.5% topical in inert carrier generally considered safe; limited to low-level use; avoid prolonged baths
- x T3: **CAUTION** — same as T2; linalool-dominant EOs generally acceptable at low levels in late pregnancy in many clinical protocols, but no RCT-level pregnancy safety data for petitgrain specifically
- x Rationale: No known uterotonic or abortifacient constituents; caution is precautionary given systemic linalool absorption; GRAS status for food-level exposure provides indirect safety context
- x *Age Restrictions (Giới hạn tuổi):**
- x Children under 2 years: **AVOID** topical and direct inhalation; diffusion only in well-ventilated space at 1 drop max
- x Children 2–6 years: ≤0.5% topical maximum; avoid direct inhalation; low-dose diffusion acceptable

- x Children 10+: Adult dilutions at conservative range (≤1.5%)
- x *Drug Interactions (Tương tác thuốc):**
- x **CNS depressants / Benzodiazepines / Sedatives:** Additive sedative effect via linalool GABAergic mechanism — monitor for excessive drowsiness; do not combine with high CNS depressant burden
- x **Anticoagulants:** Geraniol (1–4%) theoretical mild antiplatelet effect at high doses; use with caution in anticoagulant therapy at >2% topical application
- x **CYP450 substrate drugs:** Limonene is a minor CYP3A4 modulator at high doses; not clinically relevant at standard aromatherapy dilutions
- x *Contraindications (Chống chỉ định):**
- x Known linalool or geraniol contact allergy (EU 26 regulated allergens present)
- x Do not use oxidised oil — increased sensitisation risk; check batch date
- x Undiluted application to mucous membranes or broken skin
- x Direct application to eyes or ear canal
- x *Quality markers (Kiểm tra chất lượng):**
- x **Adulteration risks (HIGH — commodity EO):** Petitgrain is a high-volume commodity with significant adulteration:
- x Addition of synthetic linalool or synthetic linalyl acetate to inferior or diluted base oil
- x Blending with other *Citrus* leaf oils (mandarin petitgrain, lemon petitgrain) which are cheaper
- x Blending with terpene fractions and synthetic acetates
- x Mislabelling Paraguay-origin oil from poor batches; verify GC/MS from supplier
- x Addition of diethyl phthalate (DEP) as fixative/diluent — detectable by GC/MS

Bảo quản
Amber glass; <25°C preferred; away from direct sunlight; nitrogen flush optional; shelf life 2–3 years sealed; 12–18 months opened (esters hydrolyse slowly on prolonged storage/oxidation); store away from heat — linalyl acetate stable but linalool oxidises to allergenic hydroperoxides
