Also known as: alpha-Bisabolol, alpha,4-Dimethyl-alpha-(4-methyl-3-pentenyl)-3-cyclohexene-1-methanol, EINECS 208-205-9, EINECS 246-973-7, UNII-36HQN158VC
INCI: BISABOLOL
Bisabolol (CAS 515-69-5) is a cosmetic active ingredient functioning as Synthetic (nature-identical) (-)-alpha-bisabolol. Sesquiterpene alcohol;. EU Regulation 1223/2009 status: permitted. Industrial safety data is also available in the chemical safety database.
Synthetic (nature-identical) (-)-alpha-bisabolol. Sesquiterpene alcohol; anti-inflammatory via 5-lipoxygenase and cyclooxygenase inhibition; skin-conditioning and soothing. Chemically identical to plant-derived bisabolol but produced by total synthesis (ISO 16128 NI=0 — synthetic). Lacks the companion terpenoids present in plant-derived chamomile-extracted bisabolol (chamazulene, apigenin, alpha-bisabolol oxides) that may contribute synergistic anti-inflammatory effects. Pharmaceutical-grade batch consistency and purity. Penetration enhancer.
Editorial assessment
EXCELLENT
Preliminary editorial note — not a computed safety verdict.
US NotesNo FDA-specific regulation; manufacturer self-regulation applies. German chamomile (primary natural source of Bisabolol) is classified as GRAS for essential oils and extractives. CIR panel confirmed safe as used in cosmetic formulations (1999 + re-review). No FDA-imposed concentration limits; typical use 0.1-1.0%. No special listing or notification requirements under MoCRA beyond standard obligations.
