Description

Hectorite CAS NO 68084-71-9 is a synthetic, high-purity smectite clay belonging to the trioctahedral hectorite group, valued for its exceptional rheological and colloidal properties. This versatile material serves as a highly effective thickener, suspending agent, and rheology modifier across diverse industrial formulations. It is a critical component for manufacturers in the personal care, coatings, pharmaceuticals, and oilfield drilling sectors seeking to control viscosity, stabilize emulsions, and enhance product performance.

Application

• Personal Care & Cosmetics: Acts as a primary thickener and suspending agent in lotions, creams, sunscreens, and color cosmetics, providing excellent skin feel and formulation stability.
• Paints & Coatings: Functions as an efficient rheology modifier and anti-settling agent in water-based and solvent-based systems, ensuring sag resistance and uniform pigment dispersion.
• Pharmaceuticals: Used as a suspending and gelling agent in topical gels, ointments, and oral suspensions, where its high purity and consistency are paramount.
• Oilfield Drilling Fluids: Employed as a viscosifier and filtration control agent in water-based drilling muds, enhancing hole-cleaning efficiency and wellbore stability.
• Industrial & Household Cleaners: Provides thixotropic properties to liquid soaps, polishes, and abrasive cleaners, preventing separation and improving cling to vertical surfaces.
• Polymer & Composite Additive: Serves as a nano-filler and reinforcing agent in polymer nanocomposites to improve mechanical, thermal, and barrier properties.

Quality Control

Our Hectorite is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous testing for key parameters including viscosity development, particle size distribution, moisture content, and chemical composition. Certificates of Analysis (COA) are provided with every shipment, and we support compliance with relevant industry standards. Specifications can be tailored to meet specific application requirements.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial use to prevent caking and maintain performance.
