The use of bioactive from natural sources in cosmetic formulations has been increasing over the years due to the search for sustainable raw materials, greater concern for safety and possible social impacts of natural resource exploitation. 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 synthetic organic filters used to achieve the SPF value of 26.3. In addition, the sunscreen formulation supplemented with rambutan extract containing 1.00% RTP shows the potential to minimize the risk of synthetic agent toxicity and a 45% reduction in the cost of sunscreen production.

多年来，由于寻找可持续的原料，对安全性的关注以及对自然资源开发的可能的社会影响，化妆品配方中天然来源的生物活性物质的使用一直在增加。植物提取物已成为工业各个领域中几项研究的主题。但是，热带水果尽管引起了人们极大的消费兴趣，但其残留物仍未开发。考虑到对公众健康的影响以及使用水果加工废料的可能性，这项工作的目的是识别，评估和开发基于红毛丹果皮提取物（Nephelium lappaceum）的防晒霜。L）作为天然添加剂，可增强最终产品的防晒系数（SPF）。植物化学筛选显示单宁和类黄酮的存在以及香豆素的缺失。即使单独使用时防晒系数低（SPF值0.4），FTP浓度为1.00％的红毛丹提取物也可将含有7.5％乙基己基甲氧基肉桂酸酯（EHMC）的配方的光保护效果（11.2）提高134％。在配方中添加红毛丹提取物显示出将合成光保护剂的使用量减少的可能性，该合成光保护剂的使用量是实现SPF值为26.3的总合成有机过滤器的约64％。此外，该防晒霜配方还添加了含有1的红毛丹提取物。
