From Forest Berry Leaf Waste to Micellar Extracts with Cosmetic Applications

Year: 2025

Type: article

Abstract: The fruit of berry plants is primarily used for industrial purposes, while the leaves are often regarded as waste. However, these leaves, rich in valuable bioactive compounds, have the potential to serve as raw materials for various industries, including cosmetics. This study compared the content of micro- and macronutrients in the leaves of wild strawberry, blackberry, and blueberry plants. It revealed a high mineral content, particularly in the leaves of wild strawberry and blackberry plants. The plant leaves were also shown to contain vitamin C and exhibited antioxidant activity. The leaves of berry plants were used to obtain micellar extracts, which were then incorporated into the formulation of prototype bath washes. A cosmetic formulation without any extracts served as a reference. In the next step, the prototype cosmetics were evaluated for their chosen properties. The findings showed that incorporating micellar leaf extracts into cosmetic formulations reduced their viscosity and ability to generate long-lasting foam, even in the presence of model sebum. Furthermore, the cosmetics formulated with the extracts exhibited a reduced capacity to emulsify fatty soils compared to the reference formulation, which could present an advantageous option for individuals with sensitive skin.
