Proanthocyanidin liposome modified by polyethylene glycol (PEG) was prepared by reverse-phase evaporation method. To obtain the higher encapsulation efficiency of proanthocyanidin liposomes, several factors, including the mass ratio of lecithin to cholesterol and the addition of surfactants and PEG, were investigated. The liposomes then can be evaluated by encapsulation efficiency, the distribution of particle size and storage stability. The results showed that the encapsulation efficiency of the liposomes was around 77.28 %, and the average particle size of the liposomes was 144.9 ± 0.1 nm. In addition, proanthocyanidin could be controlled to release on simulated skin in vitro. These data confirmed that the liposomes could be employed to extend proanthocyanidin’s shelf life and to provide more convenience and better performance for its usage in cosmetics.
