Glyceryl monostearate
Emulsifying Performance: With an HLB value of 3.8, it demonstrates effective emulsifying capabilities, making it particularly useful in industrial applications that require stable water-in-oil emulsions.
Versatile Solubility Profile: It dissolves readily in hot organic solvents and oils, but remains insoluble in water, allowing flexible use across diverse formulation systems.
Safety for Use in Food: Recognized as safe by the FAO/WHO with no specified limit on Acceptable Daily Intake (ADI), supporting its use in food-grade and industrial products.
Thermal Stability: Exhibits a high boiling point of 410.96°C and a melting point between 78–81°C, reflecting its stability under high-temperature processing conditions.
Glyceryl monostearate appears as a white or light yellow waxy solid that is both odorless and tasteless. With a relative density of 0.97 and a melting point range of 56-58°C, it exhibits solubility in hot organic solvents such as ethanol, benzene, acetone, and various oils, including mineral and fatty oils. However, it is insoluble in water. Under vigorous stirring, it can form an emulsion in hot water, which demonstrates its ability to disperse. The HLB value is 3.8, indicating its emulsifying properties.
Notably, its Acceptable Daily Intake (ADI) is not restricted, as confirmed by the FAO/WHO in 1994, reflecting its safety for consumption. This compound's versatility in different solvents and its emulsion-forming capability make it valuable in various industrial applications, particularly in the formulation of emulsions and other products where water and oil phases need to be combined effectively.
