Description

Stearalkonium Hectorite

Stearalkonium Hectorite is a high-performance, organo-modified clay used in pharmaceutical, cosmetic, and personal care formulations as a rheology modifier, stabilizer, and suspension agent. Derived from hectorite clay and modified with stearalkonium ions, it provides excellent thickening and stabilizing properties in both aqueous and non-aqueous systems. Stearalkonium Hectorite
• Is an organically modified hectorite clay for rheology and stabilization control
• Is used as a suspending agent, thickener, and viscosity enhancer
• Is suitable for creams, lotions, gels, and anhydrous systems
• Provides long-term stability and uniform dispersion of actives and pigments
• Is manufactured under Good Manufacturing Practice (GMP) certified conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data
Stearalkonium Hectorite appears as a fine, off-white to cream-colored powder that swells in the presence of suitable polar solvents to form clear, stable gels. It is compatible with a wide range of oils, waxes, and surfactants used in topical and cosmetic formulations.
In pharmaceutical, cosmetic, and personal care applications, Stearalkonium Hectorite is used in:
• Topical creams, lotions, and gels for viscosity modification and stability
• Cosmetic formulations such as foundations, sunscreens, and color cosmetics
• Suspension systems requiring stabilization of pigments and active ingredients
• Anhydrous and solvent-based systems such as ointments, pastes, and emulsions
• Controlled rheology systems for smooth texture and spreadability
Stearalkonium Hectorite functions through thixotropic gel formation, enhancing stability and suspension of insoluble components while improving the sensory properties of formulations. It is especially valued for its ability to prevent sedimentation and phase separation.
CarboMer supplies Stearalkonium Hectorite with control over moisture content, particle size, purity, and rheological performance. Material is suitable for regulated pharmaceutical, cosmetic, and personal care applications.
The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in laboratory, pilot, and commercial-scale quantities. Minimum order quantities (MOQ), lead times, and documentation, including CoA and SDS, are provided upon request.
Each batch is tested for identity (IR, XRD), loss on drying, viscosity performance, pH, and microbial purity. Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation accompany every shipment.
As with all CarboMer rheology modifiers and excipients, Stearalkonium Hectorite is supported by formulation expertise, regulatory compliance support, and a secure global supply chain to ensure reliable, safe, and effective product performance.
