Where is Quaternium-18 bentonite used?

• Non-aqueous systems: rheology modifier controlling viscosity and preventing settling
• Oil-based industrial formulations: builds a stable gel structure
• Personal care: thickens and stabilizes anhydrous products such as lipsticks and mascaras
• Solvent-borne paints: prevents pigment settling and sagging
• Adhesives and sealants: builds thixotropic body in solvent-based systems
• Oil-phase systems: suspending agent for uniform dispersion
• It keeps active ingredients or fillers evenly distributed throughout shelf life.
