Description

Sodium Cetyl Stearyl Sulfate is a high-purity anionic surfactant derived from a blend of cetyl and stearyl alcohols. This compound is valued for its excellent emulsifying, wetting, and cleansing properties, making it a critical component in formulations requiring mild yet effective surface activity. It is primarily utilized by manufacturers in the personal care, cosmetics, and pharmaceutical industries to create stable, high-quality emulsions and cleansing products.

Application

• Primary Surfactant in Personal Cleansers: Used as a key foaming and cleansing agent in shampoos, body washes, and facial cleansers for its mildness and rich lather.
• Emulsifying Agent in Cosmetics: Essential for stabilizing oil-in-water (O/W) emulsions in lotions, creams, and moisturizers.
• Pharmaceutical Preparations: Employed as an emulsifier and wetting agent in topical ointments, creams, and medicated cleansers.
• Industrial & Institutional (I&I) Cleaners: Acts as a surfactant in formulations for hard surface cleaners and industrial degreasers.
• Textile Processing Aid: Functions as a wetting and scouring agent in textile manufacturing and finishing.

Quality Control

Our Sodium Cetyl Stearyl Sulfate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, composition, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, sulfate content, and unreacted alcohol levels are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
