Plants began to be used for therapeutic purposes from the beginning of human history and it was in the search for food for their survival that many toxic or healing properties of various plants were discovered. Many plants of the Brazilian flora have been used to treat diseases and natural products are becoming increasingly important and becoming an alternative to synthetic remedies. Copaiba oil-resin is a natural antibiotic with great potential for effectiveness against gram-positive bacteria, being widely used as a healing and anti-inflammatory in the treatment of infections. The study will be carried out by developing emulsions using copaiba oil resin, Tween 20 and distilled water, through an experimental design called Scheffé Network to evaluate which formulation has the best performance. The emulsion with the best performance will be submitted to rheological tests, pH tests, stability tests and evaluation of the synergistic effect of the antioxidant activity. The project will be carried out at the Laboratory of Technology of Surfactants and Separation Processes (LTT-IQ) in partnership with the Laboratory of Biotechnology of Natural Polymers (BIOPOL-CB), the collaboration enables the performance of the proposed analyses.
