The basic properties of emulsifier sucrose ester.

Time：2022-12-27

Sucrose esters are formed by the dehydration condensation of sucrose with fewer than 8 fatty acid molecules under appropriate conditions. In practice, it usually refers to sucrose esters with more than three esters. When more than 6 of the 8 hydroxyl groups of sucrose are esterified, it is referred to as "esterification degree = 6-8," known as SPE, or sucrose ester emulsifier. This product is mainly a mixture formed by the esterification with fatty acids, and the properties of the fats with an esterification degree of more than 6 hydroxyl groups are similar to those of edible oils.

　　Sucrose ester emulsifierIt is formed by the dehydration condensation of sucrose and less than 8 fatty acid molecules under appropriate conditions. In fact, it usually refers to sucrose esters with more than three esters. When more than 6 of the 8 hydroxyl groups of sucrose are esterified, the "esterification degree = 6-8" is referred to as SPE, which is the sucrose ester emulsifier. This product is mainly a mixture formed by the esterification with fatty acids, and the properties of the fatty acids with more than 6 hydroxyl groups are similar to those of edible oils. Its physical properties, functions, and applications depend on the type, and it is a high-performance non-ionic surfactant. Part of it is a hydrophilic group, and the long-chain fatty acid part is a lipophilic group. The more monoesters, the stronger the hydrophilicity; it is harmless to the human body, does not irritate the skin and membranes, is non-toxic, non-polluting, and completely biodegradable.

Sucrose ester emulsifier is a non-toxic, tasteless, odorless, and non-irritating white or light yellow powdery, waxy, or resinous substance. When used, it is mainly slightly soluble in water, soluble in ethanol, monoesters are soluble in hot water, while diesters and triesters are insoluble in water. It also has a good emulsifying effect on oil and water. Its hydrophilic-lipophilic balance (HLB) can be adjusted within a certain range, with high values of 11-13 and low values of 3.5-4.0. Sucrose ester emulsifier is easily soluble in hot water, while its solubility in water, ethanol, diesters, and polyesters is poor, but it is good in oil. The ratio of monoesters to diesters (or polyesters) can be adjusted to achieve the desired HLB value. If the sucrose ester emulsifier has good compatibility with drugs, the drug release rate is fast. In addition, this product can also be used as an emulsifier for oral medications and a solubilizer for difficult-to-dissolve drugs such as vitamins A, D, or others, and can also be used as a binder or protective film material for ointments, suppositories, tablets, and vitamin suspensions.
