Poly(ethylene glycol) diacrylate is widely used in the field of biomaterials due to its biocompatibility and ability to form hydrogels. It is commonly employed in tissue engineering to create scaffolds that support cell growth and tissue regeneration. The material’s crosslinking properties make it suitable for 3D bioprinting, enabling the fabrication of complex structures for medical applications. Additionally, it is utilized in drug delivery systems, where its hydrogel form can encapsulate and release therapeutic agents in a controlled manner. In the cosmetics industry, it serves as a key component in formulations for skin care products, providing moisturizing and stabilizing effects. Its versatility also extends to industrial applications, such as coatings and adhesives, where it enhances durability and performance.
