Ethoxylated Castor Oil (PEG HCO)

Ethoxylated Castor Oil (PEG HCO)


Ethoxylated castor oil and ethoxylated hydrogenated castor oil (also known as: PEG-n-CO and PEG- n-HCO) are ethylene oxide condensates of castor oil and hydrogenated castor oil. The number of moles of ethylene oxide can vary

Different grades of PEG-n-CO and PEG-n-HCO are available on request.

  • PEG-n-CO and PEG-n-HCO are supplied in
  • drums (200 kg) IBC
  • bulk (ISO containers)

The products with a number of ethylene oxide moles above 25 per oil are used as stabilizers and emulsifiers:

  • Used for preparation of vitamins, insecticides, pesticides and fragrances in water.
  • Used in cosmetic products (for example lotions, creams, shaving foams and shampoos).
  • Used in textile auxiliaries (for example softeners , antistatic oils, fibre lubes and dyeing aids).
  • Used in metalworking lubricants (for example soluble cutting oils and tube and wiredrawing lubes).
  • Used in paints ( for emulsification of pigment dispersions, universal tints and colorants).
  • Castor Oil Ethoxylates have many uses, primarily as nonionic surfactants in various formulations both, industrial & domestic. These are also used as cleaning agents, antistatic agents, dispersants or emulsifiers, defoamers, softeners in textile formulations.

PEG-7-CO and PEG-7-HCO are used as water-in-oil emulsifiers for the preparation of creams, lotions and similar applications.

PEG-n-HCO products are preferred over PEG-n-CO when higher oxidation stability, lighter colour, less odour or higher melting point is required.
