Usage
|
1. Pharmaceutical and Formulation Field: Enhancing Drug Solubility and Delivery Efficiency
With higher water solubility than β-cyclodextrin, it can serve as a solubilizer and inclusion carrier for poorly soluble drugs.
Helps drugs form stable complexes, improves the dispersibility of drugs in aqueous solutions, and facilitates formulation development (e.g., oral liquids, injections).
2. Biological and Food Field: Regulating Metabolism and Optimizing Product Properties
It can stimulate fatty acid synthesis, and be used in related biological metabolism research or as a carrier for metabolic regulatory components in functional foods.
Can encapsulate off-flavor components or active substances in food, balancing solubilization effect and stability to optimize food flavor and quality.
