Description

Heptadecyltrimethylammonium Methyl Sulphate is a high-purity quaternary ammonium salt (quat) surfactant, widely recognized for its potent cationic properties and excellent compatibility. This compound is essential for formulations requiring strong emulsification, antistatic effects, and surface modification. It serves as a critical raw material for manufacturers in the personal care, textile processing, and specialty chemical synthesis industries, where reliable performance and consistent quality are paramount.

Application

• Hair Conditioners & Fabric Softeners: Acts as a primary cationic surfactant, providing excellent softening, antistatic, and conditioning properties.
• Emulsion & Dispersion Stabilizer: Used in the formulation of agrochemicals, coatings, and polymer emulsions to enhance stability and particle distribution.
• Textile Auxiliary: Functions as a softening agent, lubricant, and antistatic agent for synthetic and natural fibers.
• Phase Transfer Catalyst: Facilitates reactions between reagents in immiscible solvents in organic synthesis.
• Biocide & Disinfectant Intermediate: Serves as a precursor or active component in formulations for industrial and institutional cleaning.
• Paper & Pulp Chemicals: Employed as a retention aid, drainage aid, and softener in paper manufacturing processes.

Quality Control

Our Heptadecyltrimethylammonium Methyl Sulphate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications and consistent performance. A comprehensive Certificate of Analysis (COA) documenting purity, physical characteristics, and test results is provided with each 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); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality and performance.
