Pha Chế & Hòa Hợp
Benzyl isothiocyanate (72.3%) promotes apoptosis and phase-2 detoxification enzyme induction in cancer cell lines via electrophilic thiol-trapping, placing it in B216's explicit anticarcinogenic constituent class.
Ref: B216 Benzyl isothiocyanate profile Chapter 14 — anticarcinogenic class designation (explicit)
The isothiocyanate group of BITC (72.3%) thiocarbamylates cysteine residues in microbial enzymes, disrupting cellular respiration and membrane integrity across Gram-positive, Gram-negative bacteria, and fungi.
Ref: class-extrapolation from mustard (allyl isothiocyanate Brassicales-order peer; Tisserand & Young 2014, Ch.13 p.717 isothiocyanate-class-cluster rail)
Aromatic isothiocyanates including BITC suppress NF-κB transcription and pro-inflammatory cytokine expression in cell culture; a class property not yet studied in nasturtium absolute specifically.
Ref: class-extrapolation from aromatic isothiocyanate class — NOT in §13 citations; flagged in hallucination_flags
As a peppery-green-floral absolute, nasturtium may elicit mild alerting arousal via olfactory-limbic pathway stimulation consistent with pungent-note aromatherapy class effects; no RCT evidence.
Ref: Tisserand & Young 2014, Ch.13 — general aromatherapy use designation only
AI-summary
No RCT-grade clinical evidence specific to nasturtium absolute has been located. The anticarcinogenic class designation for BITC (72.3%) rests on in vitro and animal research cited in B216 Chapter 14. The most relevant safety study is Adebiyi et al 2004, establishing a reproductive NOAEL of 12.5 mg/kg/day in rats with fetal toxicity at 25 mg/kg/day — the direct basis for the conservative 0.5% adult dermal cap (100× UF) and 0.26% pregnancy cap. Benzyl cyanide (2.0%) is subject to IFRA 2009 100 ppm finished-product ceiling, though B216 notes organic cyanides are far less acutely toxic than inorganic HCN. This is primarily a niche perfumery absolute with extremely limited therapeutic-use data.

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Perfumery blending | 0.1–0.3% in finished formula | Primary use. At 0.3%, benzyl cyanide is ~60 ppm — within IFRA 2009 100 ppm cap. Contributes peppery-green-floral nuance. Do not exceed 0.5% in any leave-on product. |
| Topical application (dilute) | Maximum 0.5% in carrier (adults); 0.26% in pregnancy | Use in a neutral carrier only. Avoid on sensitive, inflamed, or broken skin. Patch-test before first use. BITC is a class-sensitizer at higher concentrations — never exceed stated caps. |
| Diffusion | 1–2 drops in 200 ml water (ultrasonic diffuser) | Sessions 15–20 min maximum. BITC vapour can irritate mucous membranes. Avoid diffusing in rooms with children, pregnant women, or persons with asthma or respiratory sensitivity. |
| Dry inhalation (personal) | 1 drop on tissue, held at arm's length | Brief olfactory impression only. Close-range inhalation not recommended. Suitable for olfactory evaluation or momentary aromatic effect at a safe distance from source. |
