Produção de emulsões a base de Oryza sativa para formulações cosméticas

Abstract

This work aimed to produce emulsions containing Oryza sativa (rice) oil, water, and a non-ionic surfactant for the formulation of cosmetics, highlighting their use on sensitive skin. The cosmetic industry is increasingly seeking products with different technologies using natural actives, which do not act aggressively when reacting with the skin. Rice vegetable oil is a natural active ingredient that, due to its composition, has antioxidant effects and great moisturizing power. Even in its pure state, it can be used for cosmetic purposes such as hair nourishment and bath oil. The emulsions were prepared using the Phase Inversion Method with the surfactant SP CRODAFOS CES MBAL-PA-(BR). To verify its stability and characteristics, microscopic analyses, pH and viscosity determination, thermal stress tests, and centrifugation were performed. It presented a whitish color and a texture similar to an ointment. It remained stable during all the analyses carried out over the thirty days following the formulation.
