Description

2-[(1-Oxo-9Z-Octadecenyl)Amino]-Ethanesulfonic Acid is a specialized anionic surfactant and biochemical intermediate derived from oleic acid. This compound matters for its unique amphiphilic structure, which provides excellent emulsifying, dispersing, and surface-active properties in demanding formulations. It is primarily needed by manufacturers in the personal care, pharmaceutical, and industrial surfactant sectors seeking high-performance, bio-based ingredients.

Application

• Personal Care & Cosmetics: As a mild surfactant and emulsifier in high-end skin cleansers, shampoos, and cream-based formulations.
• Pharmaceutical Intermediates: Used in the synthesis of specialized drug delivery systems and active pharmaceutical ingredients (APIs).
• Industrial Surfactants: Serves as a key component in industrial cleaners, textile processing aids, and emulsion polymerization.
• Biochemical Research: Utilized as a substrate or intermediate in enzymatic studies and membrane protein research.
• Lubricant Additives: Functions as an anti-wear or friction-modifying additive in specialty lubricant formulations.
• Agricultural Adjuvants: Enhances the efficacy of pesticides and herbicides by improving spreading and adhesion on plant surfaces.

Quality Control

Our 2-[(1-Oxo-9Z-Octadecenyl)Amino]-Ethanesulfonic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong acids and oxidizing agents.
