Description

Aspartic Acid, n-(3-Carboxy-1-Oxo-3-Sulfopropyl)-n-Octadecenyl-, Tetrasodium Salt is a high-purity, anionic surfactant derived from aspartic acid and oleyl alcohol, known for its excellent chelating, dispersing, and surface-active properties. This specialty chemical is valued for its biodegradability and effectiveness in harsh aqueous conditions, offering a more sustainable alternative to traditional phosphonates. It is essential for formulators in the detergent, personal care, and industrial cleaning sectors seeking high-performance, eco-friendly ingredients.

Application

• Detergent & Cleaner Formulations: Acts as a powerful builder and dispersant in liquid and powder detergents, enhancing cleaning efficiency by sequestering calcium and magnesium ions.
• Personal Care Products: Used in shampoos, body washes, and facial cleansers as a mild surfactant and foam booster with good skin compatibility.
• Industrial & Institutional (I&I) Cleaning: Key component in scale and corrosion inhibitors for industrial water treatment and in heavy-duty cleaning formulations.
• Textile Processing: Serves as a dispersing agent and chelant in dyeing and scouring baths to prevent metal-ion interference and improve color fastness.
• Agricultural Formulations: Employed as a stabilizer and compatibility agent in pesticide and fertilizer solutions.
• Oilfield Chemicals: Functions as a scale inhibitor in production wells to prevent mineral scale deposition.
