What is Polyethylene glycol monooleate?
Polyethylene glycol monooleate (CAS 9004-96-0), commonly referenced as PEG monooleate, is a nonionic ester produced from oleic acid and polyethylene glycol. Also known as glycol oleate.
Where is Polyethylene glycol monooleate used?
- Personal care and cosmetics: emulsifier and solubilizer in creams, lotions, and cleansing formulations
- Textile and leather processing: fiber lubricant and softening agent that reduces friction during spinning, weaving, and finishing
- Metalworking fluids: lubricity and emulsification in cutting and rolling oil formulations
- Food processing: emulsifiers and carriers in food-grade variants
- It stabilizes oil-in-water systems.
Good to know: HLB value shifts with the PEG chain; common grades are PEG-200, PEG-400, and PEG-600.
