Description
What Is Glycerol Monooleate?
- Chemical identity: A monoester of glycerol and oleic acid (C18:1), typically appearing as a yellowish, waxy solid or viscous liquid.
- HLB value: ~3.6 (lipophilic), making it ideal for water-in-oil (W/O) emulsions.
Key Benefits
- Emulsification: Stabilizes W/O emulsions, especially in creams, lotions, and fat-based systems.
- Lubrication: Reduces friction in processing equipment and tablet manufacturing.
- Moisture retention: Enhances hydration in topical and food applications.
- Controlled release: Used in pharmaceuticals to modulate drug release profiles.
- Anti-spattering: Prevents fat spattering in frying applications.
