Description

Sodium Monododecyl Phosphate (Contains <10% Sodium Didodecyl Phosphate) is a high-purity anionic surfactant derived from lauryl alcohol and phosphoric acid. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a versatile functional ingredient. It is essential for formulators in industries requiring mild yet effective surface activity and compatibility with various ionic systems. Key sectors include personal care, pharmaceuticals, and specialty industrial applications.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in creams, lotions, and cleansing products due to its mildness and skin compatibility.
• Pharmaceutical Formulations: Used in topical drug delivery systems, ointments, and as an excipient for its emulsifying and solubilizing characteristics.
• Industrial Emulsions & Dispersions: Serves as an effective emulsifying agent for polymerization processes and in the formulation of lubricants, textile auxiliaries, and agrochemicals.
• Detergents & Cleaning Agents: Functions as a wetting agent and foam booster in specialty cleaning formulations where phosphate-based surfactants are specified.
• Metal Treatment & Corrosion Inhibition: Employed in surface treatment baths and corrosion inhibitor packages for its film-forming and anti-wear properties.
