Description

Castor Oil, Ethoxylated Propoxylated is a nonionic surfactant derived from natural castor oil through a controlled reaction with ethylene oxide and propylene oxide. This chemical modification imparts unique hydrophilic-lipophilic balance (HLB) properties, making it an exceptionally versatile and effective emulsifier, solubilizer, and wetting agent. It is a critical raw material for formulators in the personal care, pharmaceutical, agrochemical, and industrial lubricant sectors seeking high-performance, bio-based ingredients.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and solubilizer in creams, lotions, hair conditioners, and makeup, providing excellent skin feel and stability.
• Pharmaceuticals: Used as a nonionic surfactant in topical ointments, creams, and transdermal drug delivery systems for enhanced drug solubility and penetration.
• Agrochemicals: Serves as a key component in pesticide and herbicide formulations, improving wetting, spreading, and emulsification of active ingredients.
• Industrial Lubricants & Metalworking Fluids: Functions as an emulsifier and lubricity additive in synthetic and semi-synthetic fluids.
• Textile Processing: Employed as a leveling agent, dye dispersant, and softener in various textile finishing operations.
• Paints & Coatings: Aids in pigment wetting and dispersion, improving the stability and application properties of water-based coatings.
