Description

Dipotassium Dodecyl Phosphate CAS NO 19045-77-3 is a potassium salt of dodecyl phosphoric acid, functioning as a versatile anionic surfactant. This compound is valued for its excellent emulsifying, dispersing, and wetting properties in aqueous systems. It is a critical ingredient for formulators in the personal care, agrochemical, and industrial cleaning sectors seeking stable, high-performance surfactant solutions.

Application

• Personal Care & Cosmetics: Used as a primary or co-surfactant in shampoos, body washes, and facial cleansers for its mildness and rich lather.
• Agrochemical Formulations: Acts as an effective emulsifier and wetting agent in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Serves as a key component in hard surface cleaners, degreasers, and metal treatment fluids for superior cleaning and surface wetting.
• Textile Processing: Employed as a scouring agent, lubricant, and antistatic agent in fiber and fabric treatment processes.
• Emulsion Polymerization: Functions as a stabilizer and emulsifier in the production of synthetic latexes, such as acrylics and styrene-butadiene rubber (SBR).
• Paints & Coatings: Enhances pigment dispersion and stability in water-based paint formulations.
