About QUATERNIUM-18 HECTORITE

Quaternium-18 Hectorite is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Detailed Analysis

Quaternium-18 Hectorite is an organoclay produced by treating naturally occurring hectorite bentonite with quaternary ammonium salts (typically from hydrogenated tallow). This modification makes it organophilic and compatible with cosmetic formulations. It functions as a suspending agent, viscosity modifier, and emulsion stabiliser. No specific restrictions apply to quaternium-18 hectorite under EU Regulation 1223/2009 beyond standard cosmetic safety provisions. Its use is well established in foundations, powders, and emulsion-based skin care products.

Known Concerns

  • ⚠ Quaternary ammonium compound - mild sensitisation potential at high concentrations
