Science
Mechanism of Action
As a quaternary ammonium compound, QUATERNIUM-81 primarily functions by neutralizing static charges and conditioning hair fibers to improve their combability, softness, and shine. There is no documented mechanism of action or direct benefit for the skin itself, as its established utility is confined to hair care applications.

Safety Profile
QUATERNIUM-81 has not undergone specific safety assessments by regulatory bodies such as CIR, SCCS, or FDA. Although some other quaternary ammonium compounds have been associated with skin irritation, allergic reactions, or formaldehyde release, these findings are not attributed to QUATERNIUM-81 directly. All cosmetic ingredients within the European Union are subject to stringent safety regulations.
