Development of a Phytocosmetic Enriched with Pequi (Caryocar brasiliense Cambess) Oil
Abstract The pulp oil of Caryocar brasiliense Camb., better known as pequi, is used in the typical cuisine of the Brazilian Cerrado region. It is also used in folk medicine to combat several types of disease of the respiratory system and skin. However, since its exploration is purely extractive, the exhaustion of this plant is already foreseen. Thus, in order to establish the sustainable use of pequi and contribute to its maintenance, this study aimed to develop a phytocosmetic with antioxidant and photoprotective properties using the oil of this fruit. Initially, the cytotoxicity of the oil was evaluated in order to establish the safety of its use and its fatty acid composition. Then, from the cream enriched with the oil, it was evaluated the antioxidant and photoprotector potentials, quantified the total phenolic content and examined the quality of the formulation. Pequi oil showed high percentages of palmitic (52.11%) and oleic (44.57%) fatty acids and absence of cytotoxicity. The analysis of the cream revealed 168.8 mg of total phenols in gallic acid equivalent per 100 g of oil. The evaluation of antioxidant activity showed an EC50 of 2.921 mg/mL and a capacity of inhibiting the lipoperoxidation process higher than 100%. The obtained sun protection factor was 11.40 at the concentration of 6.25 mg/mL. The quality tests revealed small disturbances in the cream stability that can be solved by further research and improvement of the formulation. The pequi oil can be converted into a phytocosmetic of great commercial value.
