Description

(2-Hydroxyethyl)Ammonium Octadecyl Sulphate is an anionic surfactant belonging to the class of alkyl sulfates, specifically featuring a long C18 alkyl chain. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a versatile functional ingredient. It is primarily utilized in industrial and specialty chemical formulations where stable emulsions and surface activity are required.

Application

• Primary emulsifier and stabilizer in the production of polymer emulsions (e.g., acrylics, vinyl acetate).
• Key ingredient in textile processing aids, including scouring, dyeing, and finishing agents.
• Formulation component for industrial and institutional (I&I) cleaning products and degreasers.
• Used in the manufacture of leather processing chemicals for fatliquoring and dyeing.
• Acts as a dispersing agent in agrochemical formulations like pesticides and herbicides.
• Potential co-emulsifier in cosmetic and personal care products such as creams and lotions.
• Additive in metalworking fluids and lubricants for its surface-active properties.
• Component in paper and pulp processing chemicals for improved fiber treatment.

Quality Control

Our (2-Hydroxyethyl)Ammonium Octadecyl Sulphate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity and performance. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and sulfate content is provided with every shipment to guarantee compliance with your specifications.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
