A stable moisturizing cosmetic emulsion was developed from babassu nut oil and high concentrations of sunscreens. Babassu nut oil was chosen because within the laboratory time-scale, this vegetable oil showed stable physicochemical properties (relative density, acidity index, and refracted index) and a good ratio between lauric and myristic fatty acids. The presence of these saturated fatty acids can confer specific activities to the cosmetic emulsion, such as antiviral, bactericidal, and anti-inflammatory activity. The prepared cosmetic emulsion, even after the centrifugation test (3000 rpm for 15 min), showed a creamy appearance with stable light-yellow coloration and the typical odor of babassu nut oil-based products. In the accelerated stability assays (pH, viscosity, and globule homogeneity), the cosmetic emulsion was kept at different temperatures (2.0 ± 0.2 °C (TG), 25 ± 2 °C (TA), and 40 ± 2 °C (TE)) and time durations (24 hours (t0), 7 days (t7), 15 days (t15), and 30 days (t30)). Finally, developed the cosmetic emulsion was investigated for occlusive properties and in vitro sun protection factor (SPF). Both were measured at room temperature and did not change significantly under the experimental conditions employed. The maximum experimental value measured in the in vitro occlusive test was equal to 34.2 ± 2.8, and the SPF was 39 ± 1.6 (t0) and 38 ± 2.9 (t30). In agreement with European and Brazilian legislations, the obtained babassu oil-based cosmetic emulsion is classified to have a high sun protection factor.

具有高防晒系数的巴巴苏油基保湿化妆乳液的开发与表征
一种稳定的保湿化妆品乳液是由巴巴苏坚果油和高浓度的防晒剂开发的。选择巴巴苏坚果油是因为在实验室时间范围内，这种植物油表现出稳定的物理化学性质（相对密度、酸度指数和折光指数）以及月桂酸和肉豆蔻脂肪酸之间的良好比例。这些饱和脂肪酸的存在可以赋予化妆品乳液特定的活性，例如抗病毒、杀菌和抗炎活性。所制备的化妆品乳液，即使在离心试验（3000 rpm 15 分钟）后，仍呈现出乳脂状外观，具有稳定的浅黄色着色和巴巴苏坚果油基产品的典型气味。在加速稳定性测定（pH、粘度和球均匀性）中，T G )、25 ± 2 °C ( T A ) 和 40 ± 2 °C ( T E )) 和持续时间（24 小时 ( t 0 )、7 天 ( t 7 )、15 天 ( t 15 )，和 30 天 ( t 30 ))。最后，研究了开发的化妆品乳液的封闭性和体外防晒系数（SPF）。两者都是在室温下测量的，在所采用的实验条件下没有显着变化。体外封闭试验测得的最大实验值等于34.2±2.8，SPF为39±1.6（t 0) 和 38 ± 2.9 ( t 30 )。根据欧洲和巴西的法规，获得的巴巴苏油基化妆品乳液被归类为具有高防晒系数。
