- Michelia alba DC (Magnoliaceae) — flower SOLVENT ABSOLUTE. Limited availability. Species disambiguation CRITICAL: white champaca ≠ [[champaca-orange]] (M. champaca) — different chemistry + 20× stricter cap.
- Hazards: Potentially carcinogenic, based on methyleugenol content (2.3%). Contraindications: None known.
- Dermal cap: EU 0.01% / IFRA 0.02% / T&Y 0.9% — driven by methyleugenol 2.3% × 0.02% dermal limit per Methyleugenol Ch.14 profile. cap_derivation =
ifra_methyleugenol_0.02pct_dermal_cap. - IFRA linalool-peroxide rail (CRITICAL): Linalool 76.3% dominant — IFRA 2009 recommends 0.1% BHT or α-tocopherol added at production time to keep peroxide levels minimal. Oxidized linalool = skin sensitizer (autoxidation class).
- IFRA methyleugenol leave-on max 0.0004% in finished product (body lotion) / SCCNFP 0.0002% (European Commission 2002). Methyl eugenol is a rodent carcinogen at sufficient oral exposure (Ch.14 profile).

Pha Chế & Hòa Hợp
Anxiolytic
Linalool and related monoterpene alcohols in the absolute modulate GABA-A receptor activity, producing sedative and anxiety-reducing effects primarily via inhalation.
Ref: Tisserand & Young 2014, Ch.13 p.524–525; class-extrapolation from linalool constituent data (T&Y Ch.14)
Mood-elevating / antidepressant
Rich floral volatile profile stimulates limbic and olfactory cortex pathways associated with positive affect, emotional regulation, and euphoria upon olfactory input.
Ref: Tisserand & Young 2014, Ch.13 p.524–525
Nervine (stress-reducing)
Linalool-dominant composition acts on the autonomic nervous system, attenuating cortisol-mediated stress responses; effect is primarily inhalation-route dependent.
Ref: class-extrapolation from linalool constituent data (T&Y Ch.14); Tisserand & Young 2014, Ch.13
Aphrodisiac
Indole and narcotic-floral constituents evoke sensory associations with arousal; supported by centuries of ceremonial and perfumery use in Southeast and South Asian traditions.
Ref: Tisserand & Young 2014, Ch.13 p.524–525; Zhu et al 1993 (chemistry)
Antimicrobial (mild, topical)
Linalool and benzyl acetate exhibit in-vitro antimicrobial activity against Gram-positive bacteria and select fungi; relevant only at the very low dermal concentrations permitted.
Ref: class-extrapolation from linalool-rich floral absolutes; Tisserand & Young 2014, Ch.13
AI-summary
No RCT-grade clinical evidence specific to Michelia alba absolute has been located. Tisserand & Young (2014) document its chemistry and safety profile; the 0.9% adult dermal cap is driven by methyleugenol content, classified as a rodent carcinogen and restricted by IFRA (2009) to 0.0004% in leave-on products and by the European Commission SCCNFP (2002) to 0.0002%. Constituent-level evidence supports anxiolytic effects of linalool via inhalation in controlled studies, but these cannot be directly extrapolated to the whole absolute. Traditional aromatherapy and perfumery use is the primary evidence base for mood-elevating and nervine actions.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Personal inhalation | 1–2 drops on cotton pad or personal inhaler | Hold 5–10 cm from nose; inhale briefly 2–3 times. Safest route — no dermal methyleugenol exposure. Preferred method for mood elevation and stress relief. |
| Aromatic diffusion | 1–2 drops in 200 ml water | Prefer tea-light burner or fan diffuser; thick absolutes may clog ultrasonic units. Limit to 15–20 min sessions. Avoid in rooms with infants or pregnant women. |
| Topical massage | 0.5–0.9% in carrier oil (hard max 0.9%) | Blend into jojoba or fractionated coconut. Apply to pulse points or back. Patch-test 24h prior. Never exceed 0.9% adult dermal cap; methyleugenol sensitization risk. |
| Skincare blend (serum or cream) | Max 0.9% in finished product | Add to unscented stable base. Avoid for sensitive or compromised skin (methyleugenol carcinogen class). Use jojoba or squalane to minimise oxidation and extend shelf life. |
Dầu nền phù hợp
Jojoba oilLiquid wax; no fatty acid oxidation, extremely stable, and scentless — preserves the delicate champaca note without competition. Ideal for low-dilution perfumery blends.
Fractionated coconut oilOdorless, stable, and non-greasy; ensures no carrier scent interference with the complex floral absolute; suitable for leave-on formulations at the strict 0.9% cap.
Sweet almond oilLight texture and faintly nutty scent complement floral absolutes; good dermal absorption at the low dilutions required for safe topical use.
SqualaneSkin-identical emollient with near-zero oxidation risk; extends blend shelf life and suits mature or dry skin applications where the 0.9% cap limits therapeutic density.
