Description

Disodium Monoethanolamine Phosphate is an organophosphate salt derived from ethanolamine and phosphoric acid, offering unique chelating and buffering properties. This compound is valued for its ability to stabilize formulations and interact with metal ions, making it a versatile functional additive. It finds significant utility in industrial water treatment, metal surface finishing, and as a component in specialty cleaning and detergent formulations where pH control and sequestration are critical.

Application

• Industrial Water Treatment: Acts as a scale and corrosion inhibitor in cooling and boiler water systems.
• Metal Surface Treatment: Used in metal cleaning, phosphating, and electroplating baths for surface conditioning and stabilization.
• Detergent & Cleaning Formulations: Serves as a builder and sequestering agent to enhance cleaning efficiency by controlling water hardness.
• Chemical Synthesis: Functions as an intermediate or catalyst in the production of other phosphorous-containing compounds.
• Textile & Leather Processing: Employed as a buffering and dispersing agent in dyeing and tanning processes.
• Paints & Coatings: Can be used as a pigment dispersant and stabilizer to improve product shelf life.

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.
