Glyceryl monostearate CAS#31566-31-1
Emulsifying Properties: With an HLB value of 3.8, it effectively forms emulsions, making it valuable in industrial applications requiring water-oil phase combination.
Solubility Versatility: Soluble in hot organic solvents and oils, yet insoluble in water, offering flexibility in formulation.
Safe for Consumption: Recognized by FAO/WHO with no restrictions on its Acceptable Daily Intake (ADI), ensuring its safety in food and industrial products.
High Melting Point: Boiling point of 410.96°C and melting point range of 78-81°C, demonstrating thermal stability for various applications.
This substance 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.
