Description

Sodium Docosyl Sulphate is a high-purity, long-chain anionic surfactant derived from behenic acid. This compound is valued for its excellent emulsifying, wetting, and foaming properties, particularly in systems requiring stability and mildness. It serves as a critical raw material for formulators in the personal care, industrial cleaning, and textile processing sectors who demand consistent performance and reliable supply chain partners.

Application

• Primary surfactant and foaming agent in premium shampoos, body washes, and facial cleansers.
• Key emulsifying agent in cosmetic creams, lotions, and hair conditioners for stable oil-in-water emulsions.
• Industrial-grade detergent and wetting agent in textile processing and leather auxiliaries.
• Component in specialty cleaning formulations for hard surfaces and industrial equipment.
• Dispersing and stabilizing agent in emulsion polymerization processes.
• Research and development applications in biochemistry and material science.

Quality Control

Our Sodium Docosyl Sulphate 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 are provided to guarantee traceability and batch-to-batch consistency for your formulation needs.

Storage

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