- Citrus x aurantifolia Christm. — Mexican type (= Key lime, West Indian lime). Rutaceae, unripe (green) fruit peel, cold expression. PHOTOTOXIC (moderate risk) + may be photocarcinogenic — khác hoàn toàn Lime distilled non-phototoxic. Mexican vs Persian: same phototox class + IFRA cap nhưng different species (aurantifolia vs latifolia) và different chemistry.
- Hazards: Skin sensitization if oxidized + Phototoxic (moderate risk) + may be photocarcinogenic. Contraindications (dermal): If applied over max use level, skin NOT exposed to sunlight/sunbed 12 hours. Cautions: Old/oxidized oils avoid.
- Chemistry Mexican (Kubeczka 2002): (+)-limonene 48.2% + β-pinene 21.1% + γ-terpinene 8.1% + sabinene 3.1% + α-pinene 2.5% + geranial 2.4% + neral 1.4% + β-bisabolene 1.8% + β-myrcene 1.3%. Non-volatile fraction (Mexican, extrapolated from Persian — Lawrence 1989 p.42–43, Dugo 1999a, SCCP 2005b): furocoumarins present; expected similar to Persian profile (bergapten + oxypeucedanin + bergamottin + citropten).
- Max dermal: 0.7% IFRA (phototoxicity cap — bergamot-lime tier, moderate risk). Rinse-off + bath + soap EXEMPT.
- Photocarcinogenic concern: Bergapten is photocarcinogenic (Young 1990). 11 cases of photodermatitis from expressed lime oil reported; photodynamic reaction experimentally produced (Opdyke 1974 p.731). The "margarita photodermatitis" clinical phenomenon derives from fresh lime juice + UV exposure — same chemistry.

Pha Chế & Hòa Hợp
antioxidant
(+)-Limonene and co-occurring monoterpenes in expressed lime peel scavenge free radicals, with demonstrated DPPH radical-inhibiting activity confirmed in vitro.
Ref: Choi et al. (2000) [via B216]
mood-elevating / uplifting
Limonene-dominant citrus vapour stimulates serotonergic and dopaminergic pathways upon olfactory transduction, producing alerting and mood-positive effects consistent with the broader Citrus genus.
Ref: class-extrapolation from bergamot (Citrus bergamia) and sweet orange (Citrus sinensis) inhalation studies; Tisserand & Young 2014, Ch.13
antimicrobial (broad-spectrum)
(+)-Limonene disrupts bacterial and fungal cell membranes at sufficient concentration; class action consistent with other expressed citrus peel oils.
Ref: class-extrapolation from lemon (Citrus limon) and bergamot (Citrus bergamia); Tisserand & Young 2014, Ch.13
digestive stimulant / carminative
Inhalation of monoterpene-rich citrus EO traditionally stimulates gastric secretion and reduces nausea via cephalic-phase digestive reflexes.
Ref: class-extrapolation from sweet orange and lemon; Tisserand & Young 2014, Ch.13
deodorant / air-purifying
High limonene content provides bacteriostatic action against odour-causing microbes; fresh tart lime top note effectively masks ambient malodours in diffusion.
Ref: Tisserand & Young 2014, Ch.13; Kubeczka (2002) [via B216]
AI-summary
No RCT-grade clinical evidence for therapeutic benefits specific to Lime Expressed Mexican was located in the available citations. Choi et al. (2000) demonstrated antioxidant activity in vitro. Phototoxicity is well-evidenced: Opdyke (1974) documented 11 cases of photodermatitis attributable to expressed lime, and Young et al. (1990) confirmed bergapten photocarcinogenicity risk underpinning the IFRA 0.7% leave-on sunlight-exposed dermal cap. Kodama et al. (1977a, 1977b) identified (+)-limonene developmental toxicity concerns, supporting pregnancy caution. Carcinogenicity evidence for (+)-limonene is mixed across Roe & Field (1965), Ishidate et al. (1984), and Lam & Zheng (1991). Traditional aromatherapy use for uplift, digestive support, and air purification is accepted within the Citrus genus class.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 3-5 drops in 100ml water (ultrasonic) or per nebuliser manufacturer guidance | Preferred route — no phototoxic dermal risk. Uplifting and deodorising. Limit to 30–60 min with ventilation. Safe via inhalation; avoid diffusing around infants under 3 months. |
| Topical massage | Max 0.7% in carrier oil (≈2 drops per 10ml; ≈6 drops per 30ml) | HARD CAP 0.7%. Avoid sun/UV exposure 12–18 h post-application. Use on covered or torso skin only. Evening use recommended. Carriers: jojoba, fractionated coconut, sweet almond. |
| Skincare formulation | Max 0.7% in leave-on product; higher permissible in rinse-off only | Night-use or fully sun-protected formulations only. SCCNFP (2000): ≤15 ppm bergapten in leave-on, ≤1 ppm in sunscreen. Use distilled lime variant for any daytime product. |
| Direct inhalation | 1-2 drops on tissue or cupped palm; inhale briefly 2-3 times | Quick uplift and nausea relief. Avoid prolonged contact with mucous membranes. Not for children under 6 years or those with respiratory hypersensitivity. |
| Compress | 2-3 drops in 1 litre cool or warm water; wring cloth, apply to covered skin | Effective for localised discomfort. Keep compress on covered skin; remove before any sun exposure. Not recommended on face due to phototoxic risk. |
Dầu nền phù hợp
Jojoba waxNon-comedogenic, near-neutral ester profile; excellent for oily and combination skin; long shelf life suits the infrequent use dictated by the tight 0.7% cap.
Fractionated coconut oilLightweight, rapid-absorbing, odourless — preserves the delicate top-note brightness of expressed lime without olfactory competition.
Sweet almond oilMild emollient, broadly tolerated; ideal base for the very low dilution (0.7%) needed to maximise skin-contact time on covered, sun-excluded areas.
Rosehip seed oilRich in linoleic acid; synergises with antioxidant EO action in evening skincare formulations where the lime nighttime-only rule is already satisfied.
