Description

Tetrasodium n-(3-Carboxylato-1-Oxo-2-Sulphonatopropyl)-n-Octadecyl-L-Aspartate is a high-performance, multifunctional anionic surfactant derived from aspartic acid and a long-chain fatty alcohol. This compound matters for its exceptional chelating, dispersing, and surface-active properties, making it highly effective in complex formulations. It is primarily needed by manufacturers in the personal care, industrial cleaning, and textile processing industries seeking biodegradable and high-efficiency ingredients.

Application

• Personal Care Formulations: Acts as a primary surfactant and foaming agent in shampoos, body washes, and facial cleansers for gentle yet effective cleansing.
• Industrial & Institutional (I&I) Cleaners: Serves as a key component in hard surface cleaners, degreasers, and detergent blends for its superior soil suspension and emulsification power.
• Textile Auxiliary: Used as a scouring agent, dye leveling agent, and dispersant in textile pretreatment and dyeing processes to ensure uniform color and remove impurities.
• Enhanced Oil Recovery (EOR): Functions as a surfactant in chemical flooding formulations to reduce interfacial tension and improve oil displacement in reservoir rock.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to improve wetting, spreading, and adhesion on plant surfaces.
• Metal Treatment & Cleaning: Effective in acid pickling and metal cleaning baths for its sequestering ability towards calcium and magnesium ions, preventing scale formation.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation of product performance.
