Besides finding some new sources, cosmetic producers tend to adopt well-known and popular ingredients already used in the health and food sectors. Presented work is focused on characterization of some complex natural sources of phenolics and their encapsulation into liposome nanoparticles. Total phenolics, flavonoids and antioxidant activity of plant extracts was determined spectrophotometrically. Extracts were then packed into liposome particles. Size of prepared liposomes was evaluated by dynamic light scattering and their stability was determined using zeta potential. Encapsulation efficiency of active compounds was evaluated by spectrophotometrical methods. Liposome particles with antioxidant properties were tested for possible genotoxic effects as well as pure extracts. In this work it was found that selected natural sources of phenolics could be packed into liposome particles with high encapsulation efficiency. Neither prepared particles nor pure extracts show genotoxic effect on model organism. Liposome particles with antioxidant ingredients can enhance the effectiveness of cosmetic products and could be also used in modern food supplements.
