Description

9-(Sulfooxy)Octadecanoic Acid 1-Sodium Salt is a high-purity, sulfated fatty acid sodium salt with unique surfactant and anionic properties. This compound is valued for its ability to modify surface tension and act as an intermediate in the synthesis of specialized surfactants and emulsifiers. It is primarily sought by manufacturers in the personal care, specialty chemical, and industrial surfactant sectors for formulating advanced products.

Application

• Specialty Surfactant Intermediate: A key raw material for synthesizing advanced anionic surfactants with tailored hydrophilic-lipophilic balance (HLB).
• Personal Care Formulations: Used in the development of mild cleansing agents, emulsifiers, and texture enhancers for shampoos, body washes, and skincare products.
• Industrial Emulsifiers: Functions as an emulsifying agent in industrial lubricants, metalworking fluids, and textile processing aids.
• Biochemical Research: Serves as a substrate or standard in enzymatic studies and lipid metabolism research due to its sulfated fatty acid structure.
• Detergent Additive: Enhances the cleaning and wetting properties in specialized detergent systems for hard surface cleaning.
• Polymer Modification: Acts as a functional monomer or additive to introduce sulfonate groups into polymers for improved solubility or ionic character.

Quality Control

Our 9-(Sulfooxy)Octadecanoic Acid 1-Sodium Salt 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 tightly sealed after opening to prevent moisture absorption and degradation.
