Castor oil polyoxyethylene ether EL-20 is widely used in six major industries: textiles, pesticides, daily chemicals, metal processing, coatings, and industrial cleaning, playing a key role as a nonionic O/W emulsifier and multifunctional additive.

Core Application Industries and Processes

Application IndustrySpecific Process/UseFunctional Role
Textile Dyeing and PrintingLeveling, dispersing, softening finishingLeveling agent, dispersant, softener, improving dye penetration and fiber feel
Pesticide FormulationsPreparation of emulsion in water (EW) and microemulsion (ME)Nonionic emulsifier, enhancing dispersion stability and efficacy spreading of active ingredients
Cosmetics and Personal CareCreams, lotions, shower gels, shampoos, makeup removersEmulsifier and solubilizer, stabilizing oil-water phase, providing gentle skin feel
Metalworking FluidsCutting fluid and grinding fluid formulationsCombines emulsifying, lubricating and anti-rust functions, extending tool life
Coatings and InksPigment wetting and dispersion, emulsion polymerizationImproves paste fineness and storage stability, enhances film gloss and leveling
Industrial CleaningHard surface cleaning, fabric washing, industrial degreasingEmulsifying dirt removal, anti-redeposition, improving oil removal efficiency, low foam and easy rinsing

Key Points of Process Applicability

EL-20 is a nonionic surfactant (CAS: 61791-12-6) with moderate HLB value, highly stable to acid, alkali and hard water, can be compounded with anionic, cationic and other nonionic surfactants, suitable for O/W emulsification systems, especially good at emulsifying mineral oils and animal/vegetable oils.

Operational Precautions

Non-hazardous, but slightly irritating to skin and eyes. It is recommended to wear protective gloves and goggles. Storage temperature 5–35°C.
