    Abstract:

    Background: The treatment of dyschromia can be conducted using dermocosmetics containing depigmenting agents, such as kojic acid. Objectives: This study aimed the development and characterization of Carnaúba wax-based micro particles, in order to disseminate kojic acid in cosmetic and dermatological products. Methods: These elements were developed and characterized by electron microscopy and spectrophotometry, in addition to the evaluation of the encapsulation effectiveness and the release profile. Results: The different formulations showed that the variation of the concentrations of the active compound did not interfere with the Solid Lipid Micro particles (SLM) morphology, showing spherical shape and variation in their sizes. The formulation that showed the best yield was M1. All formulations showed low effective encapsulation effectiveness, varying approximately between 5 and 15%. Conclusion: The stirring speed and the stirring time are critical factors in the obtainment process and in the morphology of solid lipid micro particles.
