Tinh dầu chiết xuất lá trà đen (tea leaf absolute)
Headspace studies (not B216-verified in absolute) report trace linalool and 2-phenylethanol; both associate with mild anxiolytic and mood-supporting effects via olfactory pathway. Causal link to this specific absolute is unconfirmed given chemistry DATA GAP.
Ref: class-extrapolation from linalool headspace literature (NOT B216-verified in absolute); Tisserand & Young 2014, p.843–844
Olfactory grounding — focus association
Cultural conditioning from East Asian tea ceremony traditions (Chinese gongfucha, Japanese chanoyu) may produce anecdotal grounding and mental clarity effect via hedonic conditioned response; no constituent-linked mechanism verifiable due to chemistry DATA GAP.
Ref: Traditional aromatherapy cultural association only; no constituent evidence; Tisserand & Young 2014, p.843–844
Anti-inflammatory — sesquiterpene class extrapolation
Headspace tea volatiles include alpha-farnesene and caryophyllane sesquiterpenes; sesquiterpene hydrocarbons class-associate with mild anti-inflammatory pathways, but concentrations in the commercial absolute are unknown — highly speculative extrapolation given chemistry DATA GAP.
Ref: class-extrapolation from sesquiterpene headspace literature (NOT B216-verified in absolute); Tisserand & Young 2014, p.843–844
Perfumery — green-floral olfactory note
Headspace studies of tea volatiles identify jasmone-class compounds, C6 leaf alcohols (cis-3-hexenol), theaspirone (norisoprenoid carotenoid-degradation marker), and methyl esters creating a recognizable green-floral signature suitable for fine perfumery blending.
Ref: IFRA 2009 cat-4 0.2% guideline confirms legitimate perfumery use context; headspace literature (NOT B216-verified absolute constituents)
AI-summary
No RCT-grade or controlled clinical trial evidence for Camellia sinensis leaf absolute. B216 (Tisserand & Young 2014, p.843–844) explicitly states 'Key constituents: No useful data could be found' — chemistry DATA GAP absolute. Sole formal safety datum: RIFM 2003 (private communication to IFRA) establishing guinea-pig sensitization threshold 0.001%, yielding IFRA category-4 cap of 0.2% for leave-on body products — a 200× safety margin applied due to HIGH-RISK sensitization. Extensive clinical evidence for dietary tea (catechins, EGCG, caffeine, L-theanine) is entirely irrelevant: non-volatile polyphenols are absent from the absolute. Primary use is niche fine perfumery, not clinical aromatherapy.

Phương pháp
Liều lượng
Ghi chú
Diffusion
2-3 drops in 100ml water
Safest route — no dermal sensitization risk. Blends well with floral and green accords. Limit to 30-min sessions; avoid enclosed spaces with children under 2 or respiratory-sensitive individuals.
Fine Perfumery Topical Blend
Max 0.2% in leave-on formulation (IFRA 2009 cat-4)
IFRA 2009 hard cap 0.2% in leave-on products. Mandatory 48-hr patch test. Avoid on sensitive, damaged, or diseased skin. Not for children under 2. Sensitization-prone: avoid dermal use entirely.
Personal Inhaler
1-2 drops on inhaler cotton wick
Suitable for brief olfactory hedonic experience without dermal sensitization risk. Not a clinical aromatherapy substitute. Discard cotton wick after 2 weeks.
Atmospheric Room Spray
0.1-0.2% in water-alcohol base
Non-dermal route for room atmosphere; alcohol base improves dispersion. Avoids 0.2% dermal cap concern. Do not spray directly on skin. Ventilate after use; avoid around infants.
Dầu nền phù hợp
SqualaneChemically inert, oxidatively stable, odourless — ideal for micro-dilution at strict 0.2% IFRA cap; minimal sensitization risk appropriate for HIGH-RISK sensitizer absolute.
Fractionated Coconut OilOdourless, lightweight, long shelf life without antioxidant addition — suitable for 0.2% perfumery micro-dilution without competing with delicate tea-absolute olfactory note.
Jojoba OilExtremely stable liquid wax ester, 5+ year shelf life, non-comedogenic — appropriate for HIGH-RISK sensitizer at strict 0.2% perfumery dilution; minimally reactive with sensitizing constituents.

Blend kinh điển
Bergamot FCF— Citrus brightness of bergamot lifts and illuminates the quiet green depth of tea leaf, recreating the beloved Earl Grey accord in its purest aromatic form.
Jasmine absolute— Shared indolic undertones and floral traces create effortless harmony — jasmine fills where tea leaf is reticent, forming a luminous contemplative floral-green.
Vetiver— Vetiver's deep smoky earthiness grounds the ephemeral green of tea, together evoking damp-earth stillness of a classical Japanese tea garden.
Sandalwood— Creamy softly woody sandalwood wraps around tea leaf's cool astringency, warming it into a meditative skin-close accord beloved in Asian-inspired perfumery.

Tóm Tắt Khoa Học
Bản dịch Việt ngữ
Max dermal 0.2% (IFRA HARD-CAP, binding) — B216 EXPLICIT verbatim: "Maximum dermal use level: 0.2%." Driven by HIGH-RISK skin sensitization, KHÔNG phải named-toxicophore.
Chemistry DATA-GAP: "No useful data could be found" (B216 EXPLICIT) — không biết chemistry cụ thể.
High-risk skin sensitization — RIFM 2003: guinea-pig sensitization threshold 0.001% (200x safety margin từ 0.2% cap). Cực kỳ nhạy cảm.
CRITICAL EO-vs-PLANT: Tea leaf absolute ≠ uống trà. Catechins/EGCG/caffeine/L-theanine là non-volatile, KHÔNG có trong absolute. Tỷ hàng tỷ tách trà hàng ngày KHÔNG liên quan đến concentrated absolute này.
Niche fine-perfumery only; không phải tinh dầu aromatherapy thông thường.
