Description

Ethyldimethyl[3-[(1-Oxoisooctadecyl)Amino]Propyl]Ammonium Ethyl Sulphate is a quaternary ammonium compound with a long-chain fatty acid amide group, designed for superior surface activity and substantivity. This specialized cationic surfactant is engineered to provide excellent conditioning, antistatic, and emulsifying properties in demanding formulations. It is a critical ingredient for manufacturers in the personal care, textile, and industrial surfactant sectors seeking high-performance cationic agents.

Application

• Hair Conditioners & Rinses: Primary conditioning agent providing excellent detangling, softness, and manageability.
• Fabric Softeners: Imparts a soft, smooth hand feel and reduces static cling on textiles and fabrics.
• Skin Care Emulsions: Used as an emulsifier and cationic conditioning agent in creams and lotions.
• Industrial Antistatic Agents: Applied in polymer processing and synthetic fiber production to control static electricity.
• Cationic Emulsifier: For oil-in-water (O/W) emulsions requiring positive surface charge stabilization.
• Corrosion Inhibitor Formulations: Acts as a filming amine to protect metal surfaces in industrial systems.

Quality Control

Our Ethyldimethyl[3-[(1-Oxoisooctadecyl)Amino]Propyl]Ammonium Ethyl Sulphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications and is suitable for its intended applications. Certificates of Analysis (COA) documenting purity, physical characteristics, and compliance are available upon request.

Storage

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