Function
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.

US Notes
No 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.
