Description

Palmitic Acid, Ethoxylated, Phosphated is a specialized nonionic-anionic surfactant derived from natural fatty acids. This unique chemical structure provides excellent emulsifying, dispersing, and wetting properties, making it a versatile performance additive. It is primarily utilized in industrial formulations where robust surface activity and compatibility with electrolytes are required. Key sectors include agrochemicals, textile processing, metalworking fluids, and personal care.

Application

• Agrochemical Emulsifiers & Adjuvants: Used as a key component in pesticide and herbicide formulations to enhance emulsion stability, spreading, and foliar adhesion.
• Textile Processing Auxiliaries: Acts as a scouring agent, lubricant, and emulsifier in fiber preparation and dyeing processes.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic coolants.
• Industrial & Institutional Cleaners: Provides detergency and emulsification in heavy-duty alkaline and acid cleaners.
• Personal Care & Cosmetics: Functions as a mild surfactant and emulsifier in rinse-off products like shampoos and body washes.
• Paint & Coating Additives: Aids in pigment wetting and dispersion in water-based coating systems.
• Leather Processing: Used in fatliquoring and dyeing processes to improve softness and uniformity.

Quality Control

Our Palmitic Acid, Ethoxylated, Phosphated is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assay, pH, and cloud point determination. Certificates of Analysis (COA) documenting key specifications are available for every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

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