Description

Quaternium-18 Bentonite is a high-performance organoclay, formed by the reaction of a quaternary ammonium salt with natural bentonite clay. This modification imparts exceptional thickening, gelling, and stabilizing properties in organic systems, making it a critical rheological additive. It is essential for formulators in industries such as cosmetics, personal care, paints & coatings, and lubricants who require reliable viscosity control and suspension in non-aqueous media. Its organophilic nature allows for effective use in a wide range of polar and non-polar solvents.

Application

• Primary rheology modifier and thickener in cosmetic formulations such as lipsticks, creams, lotions, and mascara.
• Gellant and suspension agent for pigments and solids in paints, coatings, and industrial greases.
• Stabilizer and viscosity enhancer in oil-based drilling fluids and lubricants for the petroleum industry.
• Key ingredient in personal care products like antiperspirants, foundations, and sunscreens for texture and stability.
• Suspension aid in pharmaceutical ointments and topical drug delivery systems.
• Thickening agent for printing inks and various specialty chemical formulations.

Quality Control

Our Quaternium-18 Bentonite is manufactured under a strict quality management system. Each batch is tested against rigorous internal specifications to ensure consistent performance, including parameters for gel formation, moisture content, and particle size distribution. While typically supplied as an industrial grade, production can be aligned with GMP principles for sensitive applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption, which can affect performance.
