Description

Polyoxyethylatedcastoroil CAS NO 8051-35-2 is a nonionic surfactant derived from the ethoxylation of castor oil, creating a versatile and effective emulsifying and solubilizing agent. Its primary value lies in its ability to form stable emulsions between water and oils, making it indispensable in formulations requiring consistent texture and performance. This product is essential for manufacturers in the cosmetics, pharmaceuticals, and agrochemical industries seeking reliable, high-quality ingredients for their end products.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and solubilizer in creams, lotions, ointments, and hair care products.
• Pharmaceutical Preparations: Used as an excipient in topical drug delivery systems, ointments, and creams to enhance drug solubility and skin penetration.
• Agrochemical Emulsions: Serves as a key component in pesticide and herbicide formulations to ensure stable oil-in-water emulsions for effective field application.
• Textile Processing: Functions as a lubricant, softener, and dye-leveling agent in fiber treatment and dyeing processes.
• Industrial Lubricants & Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in water-based lubricants and cutting fluids.
• Leather Processing: Used as a fatliquoring agent to soften leather and improve its quality and durability.

Quality Control

Our Polyoxyethylatedcastoroil is manufactured under a strict quality management system. Each batch is tested to ensure it meets consistent specifications for critical parameters such as hydroxyl value, saponification value, and ethylene oxide content. A Certificate of Analysis (COA) is provided with every shipment, documenting compliance with agreed-upon standards. We can support compliance requirements for various applications, including those referencing pharmaceutical (e.g., USP/NF) or cosmetic-grade specifications.

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 easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen blanket) to maintain product integrity. Keep away from strong oxidizing agents.
