Plant extracts have been the subject of several studies in various fields of industry; however, tropical fruits, despite arousing great interest for consumption, and their remains are still unexplored. Considering the impact on public health and the possibility of using wastes from fruit processing, the aim of this work is to identify, evaluate and develop a sunscreen based on rambutan peel extracts (Nephelium lappaceum L) as a natural additive for enhancing the final product sun protection factor (SPF). The phytochemical screening revealed the presence of tannins and flavonoids and the absence of coumarins. Even presenting a low sunscreen factor when used alone (SPF value 0.4), rambutan extract at 1.00% FTP concentration improved the photoprotective result (11.2) of the formulation containing 7.5% of ethylhexyl metoxycinnamate (EHMC) by 134%. The addition of rambutan extract in the formulation shows the potential to reduce the use of synthetic photoprotectors by about 64% of the total sy...
