Description

Laureth-3 Phosphate is a nonionic surfactant phosphate ester, valued for its excellent emulsifying, wetting, and dispersing properties. This versatile chemical intermediate is crucial for formulators seeking to create stable, high-performance products with mild characteristics. It is primarily used by manufacturers in the personal care, industrial cleaning, and textile processing industries.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and surfactant in shampoos, body washes, facial cleansers, and other rinse-off products, providing a rich lather and mild feel on the skin.
• Industrial & Institutional (I&I) Cleaning: Used in formulations for heavy-duty degreasers, alkaline cleaners, and metalworking fluids due to its stability in alkaline conditions and effective emulsification of oils.
• Textile Processing: Serves as a lubricant, antistatic agent, and wetting agent in fiber and yarn processing, as well as in dyeing and finishing baths.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading, wetting, and penetration on plant surfaces.
• Emulsion Polymerization: Functions as an emulsifier and stabilizer in the production of acrylic, vinyl acetate, and other polymer lattices.
• Metal Treatment: Employed in acid pickling and phosphating baths to improve wetting and surface preparation.
