Description

Sodium Tetradecyl Sulfate is a high-purity anionic surfactant and sclerosing agent. Its primary value lies in its potent surface-active and foam-stabilizing properties, making it a critical component in specialized formulations. This compound is essential for manufacturers and researchers in the pharmaceutical, cosmetic, and advanced material sectors seeking reliable, high-quality raw materials.

Application

• Pharmaceutical Sclerotherapy: As the active ingredient in injectable solutions for the treatment of varicose veins and venous malformations.
• Cosmetic & Personal Care: Used as a primary or secondary surfactant and foaming agent in shampoos, body washes, and shaving creams.
• Industrial & Institutional Cleaning: A key component in high-performance detergents, degreasers, and foam cleaners for hard surfaces.
• Textile & Leather Processing: Functions as a wetting agent, emulsifier, and dispersant in dyeing and finishing processes.
• Research & Development: Serves as a model anionic surfactant for studies in colloid science, emulsion stability, and micelle formation.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide sprays to enhance spreading and adhesion on plant surfaces.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
