Pha Chế & Hòa Hợp
Earthy-mossy olfactory profile from physodone depsidone (4.7%) and methyl β-orcinolcarboxylate orsellinate (3.6%) provides deep sensory grounding via limbic olfactory pathway; historically deployed as chypre/fougère base anchor in classical fine perfumery.

Depsidone compounds (physodone 4.7%, 2'-o-methylphysodone 1.1%) are documented antimicrobials in broad lichen-chemistry literature; no specific clinical data for treemoss absolute at the dermal-safe dilution of ≤0.1% where pharmacological contribution is negligible.
Ref: class-extrapolation from lichen depsidone antimicrobial literature; not cited in B216 p.869–870
β-Sitosterol and stigmasterol combined (8.0% MAJOR-DOM) are established phytosterols with well-documented anti-inflammatory activity; pharmacological contribution at ≤0.1% dermal cap is negligible in practice.

AI-summary
No RCT-grade clinical evidence for therapeutic applications of treemoss absolute. Clinical data is dominated by safety and sensitization studies. Heisterberg et al (2011) reported 50/1503 (3.3%) positive patch-test reactions in a large European dermatitis cohort at 1%. Schnuch et al (2007a) found 45/1658 (2.7%) positive in a comparable cohort. Larsen (1977) documented 30% positivity (6/20) in a fragrance-sensitive cohort at 5%. Johnson et al (2004) found ZERO sensitization in a mouse-ear LLNA study (0.5–20%), illustrating species-divergence from human data. Opdyke (1975) confirmed non-phototoxicity and acute oral LD50 of 4.33 mL/kg. SCCNFP (2001a) and IFRA (2009) established a combined treemoss+oakmoss maximum of 0.1% in leave-on cosmetics. Classified HIGH-RISK skin sensitizer (Tisserand & Young 2014, p.869–870).

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 1–2 drops in 100 ml water | Primary safe route; classic chypre/fougère aromatic anchor. No dermal contact. Avoid in rooms with children under 2 or fragrance-sensitive individuals. Ventilate well. |
| Passive inhalation | 1 drop on tissue or diffuser bead | Hold tissue at distance from skin. Do not use near children under 2. Useful for brief grounding aromatic sessions or perfumery study. |
| Topical leave-on (perfumery) | Max 0.1% in finished product | Combined treemoss+oakmoss cap: 0.1% (SCCNFP 2001a + IFRA 2009). Not for therapeutic skincare. Avoid hypersensitive/damaged skin. Children under 2: contraindicated. Patch-test mandatory. |
| Rinse-off products | Max 0.1% in finished product | Same IFRA 2009 combined cap applies (treemoss+oakmoss 0.1% total). Not recommended for therapeutic use. Avoid for children under 2 and fragrance-sensitive individuals. |
