Description

Phosphoric Acid Mono-n-Dodecyl Ester Sodium Salt is a high-purity anionic surfactant derived from lauryl alcohol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in aqueous systems. It is a critical raw material for formulators in the personal care, industrial cleaning, and textile processing industries seeking reliable performance and supply chain consistency. Its specific structure offers advantages in stability and compatibility over other surfactant classes.

Application

• Personal Care & Cosmetics: Primary emulsifier and stabilizer in creams, lotions, and hair care products.
• Industrial & Institutional (I&I) Cleaners: Key component in heavy-duty degreasers, metal cleaners, and alkaline cleaning formulations.
• Textile Processing: Used as a wetting agent, emulsifier, and antistatic agent in fiber treatment and dyeing processes.
• Emulsion Polymerization: Serves as an anionic surfactant in the production of synthetic latexes, such as acrylics and styrene-butadiene rubber (SBR).
• Agricultural Formulations: Employed as an emulsifier and dispersant in pesticide and herbicide concentrates.
• Metalworking Fluids: Functions as a lubricity agent and emulsifier in soluble oil and semi-synthetic coolants.
• Paints & Coatings: Aids in pigment dispersion and stabilization in water-based paint systems.

Quality Control

Our Phosphoric Acid Mono-n-Dodecyl Ester Sodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for active content, pH, moisture, and ionic composition. Certificates of Analysis (COA) documenting these results are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
