Used as a surfactant and solubilizing agent in pharmaceutical and cosmetic formulations to improve drug delivery, stability, and texture. Enhances absorption of active ingredients across biological membranes. Commonly found in topical creams, ointments, lotions, gels, and injectable preparations. Acts as a stabilizer for proteins and nanoparticles in biopharmaceutical products. Also utilized in cell culture applications to protect cells from shear stress in bioreactors and in research to safeguard cells from damage, such as in ischemia studies. Its thermoreversible properties make it suitable for use in gels that liquefy upon cooling and solidify at body temperature. Additionally, employed in medical products like wound care solutions and nanoparticle delivery systems to enhance cellular uptake.
