Biodiesel has been featured on the world market for fuels come from renewable material and be less polluting when compared to petroleum fuels. Being of animal or vegetable, biodiesel also presents the same routes degradation of these materials. This work was carried out with the objective to evaluate the chemical and physical properties in oxidative stability, storage and termoxidative process of soybean methyl biodiesel additive with and without antioxidant. The influence of time and incidence of light parameters on the quality of biodiesel were evaluated from characterizations of acid index, peroxide index, kinematic viscosity and specific mass. The results suggest the best performance to oxidative stability biodiesel additive with 1000 mg.mL-1 BHA, as well as samples that were not subject to the incidence of light.
