- Acacia farnesiana L. (Mimosaceae) — flower SOLVENT ABSOLUTE (not essential oil). Contains ~25% volatile constituents; costly niche perfumery material unlikely to be used in significant quantities.
- Hazards: None known. Contraindications: None known. Clean T&Y profile despite methyl salicylate content (<5.0% per EFFA).
- Dermal cap 5.0% (framework default). Non-phototoxic. 4% on 25 volunteers = neither irritating nor sensitizing (Letizia 2000 p. 27–29). Undiluted moderately irritating to rabbits.
- Acute toxicity: Oral LD50 rats > 5 g/kg; dermal LD50 rabbits > 5 g/kg (Letizia 2000). Methyl salicylate ADI 0.5 mg/kg JECFA 1967 (2-year dog feeding + safety factor 100).
- Key regulatory rails: Methyl salicylate Health Canada 1% topical cap (Cosmetic Ingredient Hotlist March 2011) — cassie <5% methyl salicylate does not suggest restriction at normal perfumery levels. Adulteration with mimosa absolute + synthetics (benzyl alcohol, farnesol, geraniol, ionones, linalool, linalyl acetate) documented (Oyen & Dung 1999).

Pha Chế & Hòa Hợp
Anxiolytic / Calming
Linalool and farnesol constituents engage calming pathways via olfactory-limbic signaling; the rich floral accord reinforces parasympathetic response consistent with class-established anxiolytic activity of linalool-rich floral absolutes.
Ref: Tisserand & Young 2014, Ch.13 p.509–510; class-extrapolation from linalool-bearing floral absolutes (jasmine, neroli)
Mood-elevating / Aphrodisiac
Complex warm-honeyed floral odorant profile with powdery-ambery facets activates limbic reward pathways; deep historical use in romantic and mood-lifting classical perfumery blends reflects widely-accepted psycho-emotional action.
Ref: Tisserand & Young 2014, Ch.13 p.509–510
Skin conditioning
Farnesol (sesquiterpene alcohol, recognized INCI skin-conditioning agent) maintains stratum corneum barrier integrity; the benzyl ester fraction imparts emollient and skin-softening properties at cosmetic use concentrations.
Ref: Letizia et al 2000, FCT p.27–29; Lawrence 1989 p.108–109
Mild anti-inflammatory
Methyl salicylate (present at <5% in absolute per EFFA specification) belongs to the salicylate class with documented COX-inhibitory activity; therapeutic contribution is limited by low final concentration in finished formulations.
Ref: EFFA methyl salicylate <5% specification; class-extrapolation from salicylate class; Leung & Foster 2003 p.131
Mild antimicrobial
Benzyl alcohol and farnesol constituents demonstrate documented broad-spectrum antimicrobial and antifungal activity against common skin pathogens in vitro at concentrations relevant to cosmetic formulations.
Ref: class-extrapolation from benzyl alcohol and farnesol literature; Lawrence 1989 p.108–109
AI-summary
No RCT-grade clinical evidence located for cassie absolute as a therapeutic entity. Letizia et al (2000) (Food & Chemical Toxicology pp.27–29) provides the primary safety dataset: acute oral and dermal toxicity, dermal irritation, and human repeat-insult patch testing at usage concentrations — all within acceptable limits for cosmetic use. Tisserand & Young (2014) Ch.13 p.509–510 cites this dataset for the 5% maximum dermal recommendation. Therapeutic claims rest on constituent-class extrapolation (linalool, farnesol, methyl salicylate) and traditional aromatherapy practice. Health Canada (March 2011) cosmetic ingredient hotlist flags methyl salicylate at 1% topical cap; at max 5% absolute in finished product, methyl salicylate exposure remains below this threshold (<0.25% in final formulation).

| Phương pháp | Liều lượng | Ghi chú |
|---|---|---|
| Diffusion | 2–3 drops in 100 ml water or warm-air diffuser | Mood elevation, relaxation, and romantic blending. Pairs well with sandalwood or ylang-ylang. Absolutes are viscous — warm briefly before adding to diffuser. Limit sessions to 30–60 min. |
| Topical massage | 1–2% in carrier oil (approx. 6–12 drops per 30 ml) | Well within 5% max dermal limit. Jojoba or sweet almond oil recommended. Ideal for stress-relief neck and shoulder massage. Avoid broken or inflamed skin. |
| Skincare blend | 0.5–1% in facial serum or cream | Best suited for dry and mature skin. Add to rosehip or argan oil for anti-aging synergy. At 1% absolute, methyl salicylate remains well below Health Canada 1% topical cap. |
| Personal inhalation | 2–3 drops on unscented tissue or inhaler wick | Short-session (1–3 min) inhalation for acute anxiety or low mood. Do not use continuously. Caution in first-trimester pregnancy; dilute well for sensitive individuals. |
| Bath | 4–6 drops pre-dispersed in 10 ml carrier oil or bath gel | Always pre-dilute before adding to bathwater — undiluted absolute floats and may irritate mucous membranes. Limit bath time to 20 min. Not for use in pregnancy. |
Dầu nền phù hợp
Jojoba oilOdor-neutral liquid wax structure is highly compatible with cassie's complex ester chemistry; non-comedogenic and shelf-stable, suitable across all skin types and application methods.
Argan oilRich oleic acid profile and prestige positioning pair naturally with this luxury floral absolute; excellent emollient base for dry and mature skin where cassie is most indicated.
Sweet almond oilClassic carrier for floral absolutes in massage; emollient, mildly nourishing, affordable, with good spreadability for full-body relaxation and stress-relief blends.
Rosehip seed oilHigh linoleic acid and retinoic acid precursor content create anti-aging synergy with cassie's farnesol skin-conditioning fraction; well-suited to mature or sun-damaged skin serums.
