(2-Hydroxypropyl)-β-cyclodextrin is widely used in the pharmaceutical industry as a solubilizing agent to enhance the solubility and bioavailability of poorly water-soluble drugs. It forms inclusion complexes with hydrophobic drug molecules, allowing them to dissolve more effectively in aqueous solutions. This property is particularly valuable in the formulation of oral and injectable medications, improving their efficacy and stability. In the food and cosmetics industries, it acts as a stabilizer and carrier for flavors, fragrances, and active ingredients, ensuring their controlled release and prolonged shelf life. Additionally, it is employed in biotechnology and research as a tool for protein stabilization and cholesterol extraction from cell membranes, aiding in the study of membrane dynamics and protein-lipid interactions. Its biocompatibility and non-toxic nature make it a versatile excipient in various applications.
