Used as a versatile surfactant and polymer modifier in drug delivery systems, enhancing solubility and bioavailability of poorly water-soluble drugs. Its amphiphilic block structure enables self-assembly into micelles, making it effective for encapsulating hydrophobic therapeutic agents. Commonly applied in nanomedicine for targeted delivery and controlled release. Also utilized in tissue engineering as a scaffold component due to its biocompatibility and tunable hydrophilic-lipophilic balance. In industrial applications, serves as a stabilizer and emulsifier in coatings, adhesives, and personal care formulations.
