Dotachem supplies Castor Oil Ethoxylate in four grades — EL-10, EL-20, EL-40 and EL-80 — covering a wide HLB range from 6 to 16.5 to meet different emulsification, solubilization, wetting and dispersion requirements. Lower EO grades such as EL-10 and EL-20 are more suitable for oil-soluble emulsification in agrochemical and industrial systems, while higher EO grades such as EL-40 and EL-80 provide stronger water solubility and are commonly used in textile auxiliaries, cosmetic formulations, pharmaceutical-related formulations and industrial cleaning systems.
Also known as Polyoxyethylene Castor Oil or Ethoxylated Castor Oil, this nonionic surfactant can help improve oil-water compatibility, active ingredient dispersion and formulation stability across different application systems.

Castor Oil Ethoxylate performs differently across its EO grade range, so grade selection should be based on HLB value, solubility and the target formulation system. Lower EO grades such as EL-10 and EL-20 have lower HLB values and are commonly used for oil-soluble emulsification in agrochemical, metalworking and industrial formulations.
Mid to higher EO grades such as EL-40 provide better water solubility, solubilization and wetting performance. They are suitable for textile auxiliaries, water-based systems, fragrance or oil solubilization, and formulations requiring improved wetting on fiber or surface materials.
EL-80, with a higher HLB range, offers stronger hydrophilicity and can support dispersion, emulsion stability and solubilization in cosmetic, pharmaceutical-related and industrial formulations. As a nonionic surfactant, Castor Oil Ethoxylate is compatible with many surfactant systems and remains practical for formulations requiring emulsification, wetting, dispersion and stability.
In pesticide and herbicide EC formulations, EL-10 and EL-20 are commonly used to help oil-soluble ingredients disperse after dilution with water. For this type of application, buyers usually need to check emulsification effect, dilution stability and compatibility with solvents or carrier oils.
In textile processing, Castor Oil Ethoxylate is used in scouring, dyeing and finishing auxiliaries. EL-40 is a common choice when the formula needs better wetting on fiber surfaces and more even processing performance. It can also help remove oils, waxes or sizing agents during washing and scouring steps.
EL-40 and EL-80 are used in cosmetic and personal care formulations where fragrance oils, essential oils or other oil-based ingredients need to be dispersed in water-based products. For these applications, formulators usually compare solubility, clarity, odor, compatibility and final product stability before confirming a grade.
In pharmaceutical-related formulations, higher EO grades may be considered when solubilization or emulsification of oil-soluble ingredients is required. Customers should confirm the required grade, technical documents and application standards before purchase.
Castor Oil Ethoxylate can also be used in industrial cleaners, metalworking fluids, coating systems, oilfield chemicals and lubrication-related formulations. Lower EO grades are more suitable when oil compatibility is important, while higher EO grades are used more often in water-based systems where wetting, solubilization and dispersion are required.
Dotachem supplies Castor Oil Ethoxylate in EL-10, EL-20, EL-40 and EL-80 grades for customers in agrochemical, textile, cosmetic and industrial sectors. As a factory-direct supplier, Dotachem helps reduce unnecessary middleman costs and supports flexible MOQ options for both trial orders and long-term bulk procurement.
Each batch is managed through a 24-hour quality control process before shipment, covering key checks such as appearance, HLB value, saponification value, cloud point, moisture and pH. This quality review helps support batch-to-batch consistency, especially for customers with repeat production, supplier qualification or incoming quality inspection requirements.
For customers who need support before placing an order, Dotachem can assist with grade selection based on the formulation system, application type and target HLB range. Free samples are available for testing before bulk purchase, and our team typically responds to inquiries within one working day.
Products are manufactured under ISO 9001 quality management standards. COA, TDS and SDS are provided as standard documents, and REACH documentation can be provided for export orders. Regular lead time is usually 7–10 days after order confirmation, with drum and IBC packaging available for FCL and LCL shipments to Europe, the Middle East, Southeast Asia and other export destinations.
Grade selection depends on the required HLB value, oil or water solubility, cloud point and application type. EL-10 and EL-20 are typically used for oil-phase emulsification in agrochemical and industrial systems. EL-40 is suitable for textile auxiliaries and water-based solubilization, while EL-80 is used where stronger hydrophilicity and emulsion stability are required. Free samples are available for testing before bulk purchase.
Castor Oil Ethoxylate should be stored in a cool, dry and well-ventilated area, away from direct sunlight and heat sources. Containers should be kept sealed to prevent moisture absorption and contamination. The recommended storage temperature is below 40°C. Under proper storage conditions, the shelf life is typically 12 months from the date of production. EL-80 is usually solid at room temperature and may require warming before use, depending on handling conditions.
