Description

Sodium Oleth-7 Phosphate is an anionic surfactant derived from oleyl alcohol ethoxylate, valued for its excellent emulsifying, wetting, and dispersing properties. This compound is particularly significant for its ability to function effectively in challenging formulations, offering stability across a range of pH levels. It is a critical ingredient for manufacturers in the personal care, industrial cleaning, and textile processing sectors seeking high-performance, phosphate-based surfactants.

Application

• Personal Care Formulations: Acts as a primary emulsifier and solubilizer in creams, lotions, and hair care products, providing a rich, stable lather and mildness to the skin.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaning formulations, and alkaline cleaners due to its robust emulsification power on oils and fats.
• Textile Processing: Serves as a wetting agent, scouring aid, and emulsifier in fiber lubrication and dyeing processes.
• Agricultural Adjuvants: Enhances the performance of pesticide and herbicide formulations by improving wetting, spreading, and penetration on plant surfaces.
• Emulsion Polymerization: Functions as an effective surfactant in the production of polymers like acrylics and styrene-butadiene, ensuring stable particle size distribution.
• Metalworking Fluids: Incorporated as an emulsifier and corrosion inhibitor in soluble oils and synthetic coolants.
