Description

Sodium Hydrogen 2-[(1-Oxooctadecyl)Amino]-4-Sulphonatobutyrate is a high-purity, anionic surfactant derived from stearic acid and aspartic acid. This compound is valued for its excellent emulsifying, dispersing, and foaming properties, making it a versatile ingredient in demanding formulations. It is primarily utilized by manufacturers in the personal care, industrial cleaning, and textile processing industries seeking mild yet effective surface-active agents.

Application

• Personal Care Formulations: Used as a primary or co-surfactant in shampoos, body washes, and facial cleansers for its mildness and rich lather.
• Industrial & Institutional (I&I) Cleaners: Acts as an effective emulsifier and dispersant in heavy-duty degreasers, floor cleaners, and metalworking fluids.
• Textile Auxiliaries: Employed in scouring, dyeing, and finishing processes to improve wetting, leveling, and fiber lubrication.
• Agricultural Adjuvants: Enhances the spreading and adhesion of pesticides and herbicides on plant surfaces.
• Emulsion Polymerization: Serves as a stabilizer in the production of synthetic latexes for paints, coatings, and adhesives.
• Leather Processing: Aids in the fatliquoring and dyeing stages to ensure uniform penetration and soft handle.

Quality Control

Our Sodium Hydrogen 2-[(1-Oxooctadecyl)Amino]-4-Sulphonatobutyrate is manufactured under a strict quality management system. Every batch is tested to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical characteristics is provided with each shipment to guarantee consistency and support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
