Cholesterol-PEG-alcohol, MW 2,000 can self-assemble in water to form micelles. The lipophilic moiety can encapsulate hydrophobic drugs whereas the hydrophilic PEG chain helps the overal water solubility of the micelles. The polymer is often used for preparation of liposome or nanoparticle drug nanocarrier. Reagent grade, for research purpose.
