• Basic Information:
  • CAS No.: 61791 - 12 - 6.
  • Chemical Composition: It is an adduct of castor oil and ethylene oxide.
  • Molecular Formula: Usually can be expressed as C57​H104​O9​(CH2​CH2​O)n​.
  • Synonyms: Ethoxylated castor oil, PEG - n castor oil, etc.
  • Trade Names: Common ones include EL series, HEL series, etc.
• Physical and Chemical Properties:
  • Appearance: It is a light - yellow to brownish - yellow liquid to paste or solid. With the increase of the addition number of ethylene oxide, its state changes from liquid to solid.
  • Solubility: It can be dispersed in water or completely soluble in water, and is also soluble in most organic solvents.
  • Stability: It is easily hydrolyzed in strong acid and 强碱 (strong acid and strong base), and has good hard - water resistance.
  • pH Value: The pH value of a 1% aqueous solution is usually between 5.0 and 8.0.
  • Saponification Value: Taking EL - 10 as an example, the saponification value is 110 - 130mgKOH/g. Different models have different saponification values, and the value decreases with the increase of the addition number of ethylene oxide.
  • HLB Value: The HLB value of EL - 10 is 6 - 7, and that of EL - 40 is 13 - 14. As the addition number of ethylene oxide increases, the HLB value increases.
• Product Characteristics: It has excellent emulsifying, dispersing, solubilizing and antistatic properties, as well as good calcium - magnesium dispersing ability.
• Preparation Method: It is obtained by the polymerization of castor oil and ethylene oxide under certain conditions.
• Application Fields:
  • Textile Field: As an antistatic agent, softener, synthetic fiber spinning oil agent, etc., it can improve the soft, smooth and bundling properties of fibers. It can also be used to eliminate the foam in synthetic sizing agents.
  • Personal Care Field: In cosmetics, it is used as an emulsifier, fat - enriching agent and emollient, and is used to manufacture shampoo, bath foam, skin - care products, etc.
  • Pharmaceutical Field: It is used as an emulsifier to manufacture liniments, creams, emulsions, etc., and can also be used as a solubilizer for water - insoluble or other fat - soluble drugs.
  • Pesticide Field: It can be used as a pesticide emulsifier, which is suitable for organophosphorus pesticides, etc., and has obvious wetting and synergistic effects.
  • Other Fields: It is also used for the emulsification of inks and printing pastes, and for preparing water - soluble metal cutting fluids.
• Packaging and Storage:
  • Packaging: Usually packed in 200 - Kg iron drums or 50 - Kg plastic drums, and can also be customized according to needs.
  • Storage: It should be stored in a dry and ventilated place, and the shelf - life is generally 1 year.
