Description

Phosphoric Acid, Dodecyl Ester, Ammonium Salt CAS NO 90605-05-3 is an anionic surfactant derived from phosphoric acid and lauryl alcohol. This compound is valued for its excellent emulsifying, wetting, and anti-corrosion properties in aqueous systems. It is primarily utilized in industrial formulations requiring stable emulsions and surface activity, such as in metalworking fluids, agrochemicals, and textile processing aids.

Application

• Metalworking Fluids: Acts as a key emulsifier and corrosion inhibitor in soluble oils and semi-synthetic coolants.
• Agrochemical Formulations: Used as an emulsifier and wetting agent in pesticide and herbicide concentrates.
• Textile Processing: Serves as a lubricant, antistatic agent, and emulsifier in fiber treatments and dyeing baths.
• Industrial Cleaners & Degreasers: Provides emulsification and surface wetting for heavy-duty cleaning formulations.
• Paints & Coatings: Functions as a dispersing agent and stabilizer in water-based coating systems.
• Personal Care: Employed as a mild surfactant and emulsifier in select rinse-off products.

Quality Control

Our Phosphoric Acid, Dodecyl Ester, Ammonium Salt is manufactured under a strict quality management system. Each batch is tested to ensure consistent chemical identity, purity, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and moisture content are available upon request to 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 material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect product performance.
