Description

Fatty Acids, C18 And C18-Unsatd., Ethoxylated Propoxylated (CAS 68604-37-5) is a nonionic surfactant derived from C18 fatty acids, modified with both ethylene oxide (EO) and propylene oxide (PO) blocks. This dual modification provides a unique balance of hydrophilic and lipophilic properties, making it a versatile and effective emulsifier, dispersant, and wetting agent. It is essential for formulators in industries such as agrochemicals, textiles, and personal care, where stable emulsions and controlled surface activity are required.

Application

• Agrochemical Emulsifiers: A key component in pesticide and herbicide formulations, enhancing the emulsification and stability of active ingredients for improved field performance.
• Textile Processing Aids: Used as a scouring, leveling, and softening agent in fiber and fabric treatment processes.
• Industrial & Institutional Cleaners: Acts as a powerful surfactant and degreaser in heavy-duty cleaning formulations for hard surfaces and machinery.
• Personal Care & Cosmetics: Serves as an emulsifier and thickener in creams, lotions, and hair care products, providing a smooth texture.
• Metalworking Fluids: Functions as an emulsifier and lubricity agent in soluble oils and coolants.
• Paints & Coatings: Aids in pigment dispersion and stabilization in water-based systems.
• Leather Processing: Used in fatliquoring and dyeing processes to improve softness and dye penetration.

Quality Control

Our Fatty Acids, C18 And C18-Unsatd., Ethoxylated Propoxylated undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as hydroxyl value, acid value, and EO/PO content are strictly monitored. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance.
