About QUATERNIUM-18/BENZALKONIUM BENTONITE
An organoclay composite combining quaternium-18 hectorite with benzalkonium chloride, used as a suspending agent and viscosity modifier in pigmented and powder cosmetic formulations.
Detailed Analysis
Quaternium-18/Benzalkonium Bentonites are organically modified bentonite clays further treated with benzalkonium chloride. They function as suspending agents and rheology modifiers, particularly in formulations containing pigments (foundations, powders) or reactive ingredients. Benzalkonium chloride is a quaternary ammonium compound with documented sensitisation potential, particularly for respiratory sensitisation (H334) in professional settings. In the final cosmetic formulation, residual benzalkonium chloride levels are typically low due to the clay binding. However, this combination ingredient requires careful safety evaluation, particularly in sprayable or inhaled products.
Known Concerns
- ⚠ Contains benzalkonium chloride - known sensitiser
- ⚠ Quaternary ammonium compound - mild irritation potential
- ⚠ Combination of two active cationic ingredients
- ⚠ Widely used in industrial and cosmetic applications
