Description

Castor Oil, Ethoxylated, Monoester With Disodium Sulfobutanedioate (Eo Ca. 80 Mol) is a high-performance, nonionic surfactant derived from natural castor oil, modified with approximately 80 moles of ethylene oxide and esterified with a sulfosuccinate group. This unique molecular structure provides exceptional emulsifying, wetting, and solubilizing properties, making it a versatile and effective ingredient in demanding formulations. It is particularly valued in industries requiring high-performance, mild, and biodegradable surfactants for personal care, agrochemicals, and industrial cleaning applications.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and solubilizer in creams, lotions, and shampoos, offering mildness and compatibility with sensitive skin.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates to enhance spreading and efficacy.
• Industrial & Institutional (I&I) Cleaning: Serves as a key surfactant in heavy-duty cleaners, degreasers, and emulsion cleaners due to its excellent oil solubilization and soil removal.
• Textile Processing: Functions as a dye leveling agent, lubricant, and emulsifier in various wet processing stages.
• Paints & Coatings: Employed as a pigment wetting and dispersing agent to improve color development and stability in aqueous systems.
• Metalworking Fluids: Provides emulsification and lubrication in synthetic and semi-synthetic metalworking coolants.
