Common Name(s): Benzaldehyde,fragrance chemical,eu-listed allergen

CAS Number: N/a

DESCRIPTION

What It Does: Provides specific aromatic character to cosmetic formulationsrequiring individual label declaration above 0.001% in rinse-off or 0.0001% in leave-on products under eu regulation.

Why It's Used: Formulators must individually declare this eu-listed fragrance allergen on product labels when concentrations exceed the threshold — separate from the generic parfum/fragrance declaration.

How It Works: Volatile aromatic molecule activates olfactory receptors in the nasal epithelium through g-protein coupled receptor binding — the specific molecular geometry and functional groups determine which olfactory receptor subtypes are activated, producing the characteristic aromatic note.

Typically Found In: Fragrance applications
