Description

Polyethylene Glycol Octadecyl Ether Sulfuric Acid is a specialized anionic surfactant derived from the sulfation of a long-chain ethoxylated alcohol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in demanding formulations. It serves as a critical intermediate and functional additive for manufacturers in the personal care, textile processing, and industrial cleaning sectors, where stable performance in acidic or solvent-based systems is required.

Application

• Emulsifier & Stabilizer in acidic or solvent-based industrial cleaning concentrates and degreasers.
• Textile Auxiliary for scouring, dyeing, and finishing processes requiring wetting and penetration aids.
• Intermediate for the synthesis of more complex anionic surfactants and specialty chemicals.
• Personal Care Formulations as a base material for creating mild anionic surfactants in select rinse-off products.
• Agricultural Adjuvants to enhance the spreading and adhesion of pesticide and herbicide formulations.
• Metalworking Fluids as an emulsifier and corrosion inhibitor component.
• Polymerization Aid in certain emulsion and suspension polymerization processes.
• Laboratory Research as a model compound for studying surfactant behavior and interfacial science.

Quality Control

Our Polyethylene Glycol Octadecyl Ether Sulfuric Acid is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as active matter content, sulfate content, and free fatty alcohol/acid levels. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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). This material is hygroscopic (moisture-sensitive) and should be kept away from strong bases and oxidizing agents to maintain stability.
