The major goal of this research work was to use the dry extract of the fruits of Jussara palm tree (Euterpe edulis Martius) in the development of a tinting shampoo (0.3% (w/v) anthocyanin extract) and an exfoliating beauty cream integrating granules from the seeds of the fruit (1%, w/v). The dry extract was characterized via determination of the content of anthocyanins by the differential pH method, antioxidant activity by the phospho-molybdenum complex methodology, and antimicrobial activity by the disc-diffusion method. The extraction yield was 2.3% (w/w) (2.25 g dry extract/100 g fruit), with an antioxidant activity of 139.0 ± 5.5% relative to that of ascorbic acid, indicating a high antioxidant capacity. The anthocyanin extract did not exhibit antimicrobial activity. The physico-chemical stability characteristics of both the tinting shampoo and the exfoliating cream were evaluated via accelerated stability studies at 0, 30, 60 and 90 days of storage at 40 ± 2 °C and 75 ± 5% relative humidity. The cosmetic products prepared were stable in relation to the physico-chemical characteristics under the conditions studied.
