The Potential Use of Cashew Apple Lignin as Photoprotector Ingredient for Cosmetics
Short Introductive summary
The use of natural polymers in the formulation of cosmetics is growing due to the general interest in sustainability and environmental issues. An alternative that fits this demand is the use of lignin as a UV absorber component. However, its dark brown color is occasionally found as a barrier to restrict its extensive use. On the other hand, the combination of lignin with metal oxide in the form of hybrid nanocomposites can reduce the dark brown color of lignin to a light brown color to help increase its applicability. In this context, this study aimed to use lignin from cashew apple bagasse (CAB) to produce hybrid nanocomposites with zinc and titanium oxides and to evaluate their antioxidant and UVA/UVB properties. The lignin-hybrid nanocomposites showed antioxidant and photoprotective properties for future application as UV absorbers in cosmetics products. The use of the low-cost and sustainable synthesis of lignin nanocomposites not only contributes to value-added nanomaterials production but also helps to mitigate the agro-waste disposal problems and the impacts caused to the environment by sunscreen ingredients.
