RESUMO:

Increasing concerns about health security, social impacts and fair trade have intensified the industrial interest in the use of natural products in commercial cosmetic formulations. Currently, several studies are focused on plant extracts, but tropical fruits such as guava, rambutan, grape and abiu remain untapped and therefore underused. This research aims to evaluate the potential of using phenolic substances rich fruit extract as a photoprotective additive agent for sunscreen formulations. Fruit extracts of Nephellium lapaceum (Rambutan), Pouteria caimito (Abiu), Psidium guajava (Guava) and Vitis spp. (Grape) aiming at the development of a commercial product adapted to the regional conditions of the state of Bahia to not only innovate in the discovery of new substances but to encourage regional economic development. Phytochemical screening revealed the presence of flavonoids and tannins and the absence of coumarins in all extracts. The literature review and patent prospection revealed that there are no works and / or cosmetic products containing in their composition extracts of the evaluated fruits, isolated or combined with photoprotective and antioxidant purposes. The extracts tested showed positive antioxidant results. The photoprotective activity was not observed when the extracts were used alone in dermocosmetic formulations. However, when associated with formulations containing synthetic sunscreens, the extracts acted synergistically, enhancing the Sun Protection Factor (SPF) more than 200.0%. The use of these actives in photoprotective formulations can favor the reduction of the concentration of synthetic organic sunscreens used in its composition, reduction of the toxicity associated with these filters, as well as the potentialization of their SPF. The production of cosmetics from substances of natural origin with such activities will be of great importance for the Brazilian industrial sector and may reduce the cost of production, considering the great biodiversity existing in the country, representing a great scientific and economic impact.
