- Phân loại nốt hương
- Middle note
- Hương thơm
- Heart/Base note; rich, deep, narcotic white floral — honey-like, waxy, indolic, slightly animalic with fresh citrus undertone; distinctly heavier and more complex than neroli EO

- Morocco ★★★★★Egypt ★★★★☆Tunisia ★★★☆☆Iran ★★★☆☆France (Grasse) ★★☆☆☆
- Tình trạng tại Việt Nam
- ⭐⭐☆☆☆ — Imported; rarely available as authentic absolute; frequently confused with neroli EO or orange blossom absolute (from concrete). Specialist aromatherapy suppliers in Hanoi/HCM carry it sporadically at premium price (estimated 800,000–2,500,000 VND / 1–5 ml)
Thành Phần Hóa Học
Section 2 — Chemical Composition (GC/MS)
| Cấu tử | Nhóm | % | Tác dụng |
|---|---|---|---|
| Linalool ★★★ DOMINANT | Monoterpenol | 15–44% | Anxiolytic, sedative, anti-inflammatory; GABAergic modulation |
| α-Terpineol | Monoterpenol | 2–21% | Antimicrobial, antifungal, mild sedative |
| Geraniol | Monoterpenol | 0–27% | Antibacterial, skin-healing, rose-like aroma contributor |
| Methyl Anthranilate | Aromatic ester (nitrogen-containing) | 4–12% | Key odorant — narcotic floral note; distinguishes hydrolate absolute from neroli |
| Linalool Oxide (cis + trans) | Monoterpene oxide | 5–10% | Calming, modifies linalool volatility |
| Benzene Acetaldehyde | Aromatic aldehyde | 2–6% | Honey-like, rosy odorant |
| Terpinen-4-ol | Monoterpenol | 1–3% | Anti-inflammatory, antimicrobial |
| Geranyl Acetate | Ester | 1–3% | Antifungal, mild calming |
| Neryl Acetate | Ester | 0.9–2% | Floral freshness, antispasmodic |
| Indole | Aromatic nitrogen compound | 0.2–2% | Intensely floral/narcotic at trace levels; key absolute signature |
| Farnesol | Sesquiterpenol | 0.3–1% | Antimicrobial, skin-conditioning |
| trans-Nerolidol | Sesquiterpenol | 0.5–1% | Anti-inflammatory, sedative |
- High linalool (>40%) + high methyl anthranilate (>10%) = traditional/cold-process hydrolate extraction → richest perfumery grade - Low linalool + high limonene + 1,8-cineol presence = industrial/adulterated sample (likely peel contamination) - Absence of linalyl acetate (major neroli EO constituent) is diagnostic — distinguishes this absolute from neroli EO - Indole and methyl anthranilate together create the distinctively "narcotic" floral signature absent in neroli EO ---

Section 4 — Therapeutic Properties
Linalool (44%+) modulates GABA-A receptors and inhibits glutamate release, reducing CNS excitability; methyl anthranilate contributes olfactory-hedonic modulation; hydrolate used traditionally as oral sedative in Middle Eastern medicine. Ref: PMID 39133687; PMID 24163946
Inhalation activates limbic-serotonergic pathways; linalool shown to reduce corticosterone in stressed animal models; ethnobotanical use as antidepressant for postnatal depression documented. Ref: PMID 24163946; Mantel F., Complement Ther Nurs Midwifery 2002;8:197–203
α-terpineol, geraniol, linalool show broad-spectrum antibacterial and antifungal activity in in vitro models; minimum inhibitory concentrations effective against S. aureus and C. albicans. Ref: PMID 24163946
Linalool reduces NF-κB inflammatory signalling; phenolic compounds contribute radical scavenging; cytophylactic effect supports skin cell renewal. Ref: Monsef-Esfahani et al., IJPR 2004
Promotes cellular regeneration; geraniol and linalool support wound healing and skin barrier repair. Ref: PMID 24163946
Tâm Lý & Năng Lượng
Section 5 — Emotional & Energetic Profile
Tâm trạng: Calming + Grounding + Uplifting (deep, stabilising calm with subtle euphoric undertone — distinct from the lighter euphoria of neroli EO)
Chakra: Heart Chakra ★★★★★ (Anahata — unconditional love, emotional healing); Solar Plexus ★★★☆☆ (Manipura — self-confidence recovery)
Ngũ hành: **Hỏa (Fire) ★★★★☆** — governs joy, the Heart meridian, emotional warmth; **Kim (Metal) ★★★☆☆** — relates to grief processing, lung/skin affinity
Cách Dùng & Pha Chế
Section 6 — Application & Formulation
Phù Hợp Loại Da
Section 7 — Skin Type Suitability
Antimicrobial properties beneficial; use at ≤0.5% to avoid comedogenic risk from resinous fractions; dilute in jojoba
Excellent — cytophylactic and skin-renewing; pair with rosehip or argan; rich waxy fractions help restore lipid barrier
Apply to dry zones; avoid heavy concentration on T-zone; 0.5% in lightweight jojoba suitable
Patch test mandatory; start at 0.2–0.3%; methyl anthranilate and indole can sensitise; IFRA limit applies
Top recommendation — promotes cell renewal, antioxidant, rich emollient fractions; use in evening serum at 0.5–1%
Not a primary brightening agent; geraniol mild skin-tone benefit; pair with rosehip for better efficacy
Anti-inflammatory linalool beneficial; avoid during active flare; use at ≤0.5% on remission skin; soothing in evening bath at low dose
Antimicrobial; pleasant fragrance contributor to scalp oils; use at 0.5% in scalp serum; not a primary hair-growth agent
An Toàn & Chống Chỉ Định
Section 8 — Safety
Giới hạn da tối đa
0.7% (IFRA 51 Category 4) — driven by methyl anthranilate content and cumulative allergen load (linalool + geraniol + limonene)
IFRA Restriction
0.7% in finished product
Thai kỳ & Cho con bú
Giới hạn độ tuổi
- Children under 2 years: **AVOID** all absolutes; methyl anthranilate and indole not evaluated for infant safety
Tương tác thuốc
- ! CNS depressants / Benzodiazepines / Sedatives:: Additive sedative effect via linalool's GABAergic activity — monitor drowsiness
- ! Anticoagulants (warfarin):: Geraniol at high doses may theoretically affect platelet aggregation; avoid therapeutic doses with anticoagulant therapy
- ! Selective Serotonin Reuptake Inhibitors (SSRIs):: Theoretical synergy — not contraindicated, but monitor mood effects
Chống chỉ định
- x Known allergy to any Citrus aurantium-derived products or any of the EU 26 allergens present (linalool, geraniol, limonene, methyl anthranilate)
- x Severe asthma or reactive airway disease (indole and methyl anthranilate may trigger at high diffusion concentrations)
- x Undiluted application to any skin surface
- x Use in confined, poorly ventilated spaces due to very high odour intensity
Kiểm tra chất lượng
- **Genuine:** Deep amber to dark brown colour; viscous; characteristic narcotic white-floral with honey-waxy depth; should NOT smell identical to neroli EO (which is lighter, fresher, and lacks the indolic-narcotic depth); GC/MS should show methyl anthranilate 4–12%, linalool 15–44%, absence of high limonene (>10% suggests adulteration) - **Adulteration risks:** Dilution with synthetic linalool; addition of synthetic methyl anthranilate to inferior material; spiking with limonene or cheap citru
Bảo quản
Amber/dark glass; cool (8–15°C preferred); away from light and heat; nitrogen flush if possible; shelf life 2–3 years sealed; 12–18 months once opened. Oxidation of linalool increases sensitisation risk — discard if rancid ---

Trong Y học cổ truyền VN
- *Nước hoa cam* (the hydrolate) widely used as flavouring in traditional confectionery and as a mild aromatic digestive tonic — this is the closest VN equivalent to the therapeutic use of the hydrolate - Flowers used in traditional perfuming of teas (trà ướp hoa cam đắng) — sedative and mood-calming intent - Not formally classified in Dược điển Việt Nam as a medicinal monograph for the absolute, but *vỏ trái cam đắng* (pericarp) is listed - Folkloric use: hoa cam placed in sleeping quarte
