Description

Laureth-4 Phosphate CAS NO 39464-66-9 is a nonionic surfactant phosphate ester, valued for its excellent emulsifying, wetting, and dispersing properties. This compound is particularly significant for formulators seeking mild, high-performance ingredients with good compatibility in aqueous systems. It is essential for manufacturers in the personal care, industrial cleaning, and textile processing industries who require effective surface-active agents.

Application

• Personal Care Formulations: Acts as a primary emulsifier and surfactant in shampoos, body washes, and facial cleansers, providing a rich lather and mildness to the skin.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, alkaline cleaners, and floor care products for its superior wetting and emulsification of oils and fats.
• Textile Processing: Serves as a lubricant, antistatic agent, and dye leveling assistant in fiber and fabric treatment baths.
• Agricultural Adjuvants: Enhances the spreading and penetration of pesticides and herbicides on plant surfaces.
• Metal Working Fluids: Incorporated as an emulsifier and corrosion inhibitor in soluble oils and synthetic coolants.
• Paint & Coating Additives: Functions as a pigment dispersant and grinding aid to improve color development and stability.

Quality Control

Our Laureth-4 Phosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with relevant industry specifications. A comprehensive Certificate of Analysis (COA) documenting purity, assay, and key physical parameters is provided with every shipment to guarantee traceability and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and potential degradation. Keep away from strong alkalis and incompatible materials.
