Where is Monoolein used?

• Food: emulsifier in bakery fats, margarine and dairy analogs to stabilize oil-water interfaces
• Pharmaceutical: forms liquid crystalline drug delivery systems, particularly cubic phase gels, enabling controlled release of active compounds
• Personal care: skin-conditioning carrier in creams and serums, improving spreadability and penetration of actives
• Cosmetics: solubilizer for lipophilic actives in water-based systems
• It functions as an emulsifier, solubilizer and moisturizing carrier in complex formulations.

Good to know: The physical state depends on temperature and purity grade. High-purity grades are sourced for parenteral and controlled-release pharmaceutical applications.
