Polyethylene glycol monoricinoleate (CAS 9004-97-1), also marketed as PEG 400 Monoricinoleate, is an ester derived from castor oil fatty acid and polyethylene glycol.

Where is Polyethylene glycol monoricinoleate used?

• Personal care: emulsifier for oil-in-water creams, lotions and conditioning products, with moisturizing properties
• Textile and leather: softening and lubricating agent in fiber treatment, yarn spinning and leather finishing
• Metalworking and industrial lubricants: emulsifier and boundary lubricant in cutting fluids and rolling oils
• Coatings and adhesives: plasticizer improving flexibility and substrate adhesion in polymer-based systems
• It functions as a non-ionic emulsifier, lubricant and plasticizer.

Good to know: The most commercially common grade is based on PEG 400; other molecular weight variants are available, selected for specific application requirements and desired solubility profiles.
