Description

Tris(2-Hydroxyethyl)Ammonium Octadecyl Sulphate is a quaternary ammonium salt surfactant with a long alkyl chain, offering a unique combination of cationic and anionic properties. This compound is valued for its excellent emulsifying, dispersing, and antistatic capabilities in complex formulations. It serves as a critical functional additive for manufacturers in the personal care, textile processing, and specialty chemical synthesis industries.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners & Textile Auxiliaries: Imparts a soft hand feel to fabrics and provides durable antistatic properties during fiber processing.
• Emulsion Stabilizer: Used in the formulation of oil-in-water (O/W) emulsions for cosmetics and industrial products, enhancing stability and texture.
• Antistatic Agent for Plastics & Polymers: Incorporated into polymer matrices or applied as a surface treatment to dissipate static charge.
• Corrosion Inhibitor Formulations: Serves as a component in specialty blends for protecting metal surfaces in various industrial fluids.
• Research & Chemical Synthesis: Utilized as a phase-transfer catalyst or a specialty surfactant in organic synthesis and material science research.

Quality Control

Our Tris(2-Hydroxyethyl)Ammonium Octadecyl Sulphate is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key parameters is provided with every shipment to guarantee consistency and support your quality assurance protocols.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
