Desenvolvimento de uma formulação de água micelar com extrato de Galdieria sulphuraria

Abstract

Brazil is one of the biggest cosmetics consumers in the world. This is mainly due to the tendency of Brazilians to seek more and more products that improve their quality of life. For this, antioxidant extracts are often incorporated in cosmetic formulations. In this context, the extremophile microalgae Galdieria sulphuraria stands out, as it produces a high amount of antioxidant compounds, besides other substances. Although promising, cosmetic applications with biocompounds from the microalgae G. sulphuraria are poorly studied. Micellar water is a cosmetic for people with a busy routine because it ensures facial cleansing in a practical way, it is multifunctional and non-aggressive. This work studied the application of the hydrophilic extract of G. sulphuraria in micellar water formulations. Initially, the microalgae was cultivated in Allen medium and the extracts were obtained from ultrasound extraction and drying in an oven. Then, the extract was incorporated into a monophasic micellar water formulation. The prototype was subjected to stability tests under different conditions and proved to be stable.
