Προσθήκη ετικέτας | Περίληψη: | Moisturizing and antioxidant agents are necessary for the health of the human body, they commonly help in the regeneration of the skin, elimination of blackheads and treatment of spots caused by external, environmental factors, poor diet, and hormonal changes. For these reasons, skincare investigation has intensified over the years, so research is being carried out every day to innovate existing products and develop new products. This research work focuses on the obtaining of a blueberry extract to be used as an antioxidant and moisturizing agent, and to analyze its encapsulation in a double emulsion Water/Oil/Water (W/O/W) to potentiate its antioxidant capacity and provide benefits to the skin. Both blueberry extract and emulsions prepared from it were analyzed and characterized. The obtained extract was characterized by UV-Vis and IR spectroscopy and other procedures were carried out to determine its reducing power. As for emulsions, these were characterized by dilution tests to know the type of emulsion formed and analysis by optical microscopy to confirm the phases of the emulsions. Also, it was evaluated the behavior of emulsions and blueberry extract against UVA and UVB radiation. Some properties exhibited by prepared emulsions, such as their moisturizing and sun protection capacity, as well as the antioxidant property of the anthocyanin extract were evaluated. Satisfactory results were obtained, demonstrating the ability of the materials obtained to reduce spots on the skin, in addition to moisturizing and protecting against UV radiation. |
