Description

Sodium Tetradecyl Sulfate is a high-purity anionic surfactant and sclerosing agent. This compound is valued for its potent surface-active properties and its role as a critical pharmaceutical active ingredient. It is essential for manufacturers in the pharmaceutical, medical device, and specialty chemical sectors requiring a reliable and consistent raw material. Sodium Tetradecyl Sulfate CAS NO 68043-79-8 is supplied under stringent quality control to meet the demands of advanced formulations.

Application

• Pharmaceutical Sclerosing Agent: The primary and most significant application is as the active pharmaceutical ingredient (API) in injectable solutions for the treatment of varicose veins and venous malformations (sclerotherapy).
• Medical Research & Diagnostics: Used in laboratory settings for cell lysis, membrane protein solubilization, and as a component in various biochemical assays.
• Specialty Detergents & Emulsifiers: Employed in the formulation of high-performance industrial and institutional cleaning products where specific foaming and wetting characteristics are required.
• Personal Care & Cosmetics: Functions as a surfactant in specialized rinse-off products, though its use is carefully controlled due to its potency.
• Textile & Leather Processing: Acts as a wetting agent and emulsifier in specific finishing and dyeing processes.
• Agricultural Adjuvants: Used in the formulation of pesticides and herbicides to enhance spreading and penetration on plant surfaces.

Quality Control

Our Sodium Tetradecyl Sulfate is manufactured and tested to meet exacting standards suitable for pharmaceutical applications. Quality is assured through a comprehensive battery of analytical tests including identification, assay, and impurity profiling. We provide full traceability and support regulatory submissions. Certificates of Analysis (COA) documenting compliance with in-house specifications are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep away from strong oxidizing agents.
