This study investigated the moisturizing action of a topical emulsion containing babassu coconut almond oil in xerotic skin volunteers treated or undergoing leprosy treatment. A total of 20 volunteers (16 men and 4 women, with a mean age of 52.2 ± 15.3) with cutaneous xerosis performed the tests after signing the informed consent form. The research subjects were instructed to use the product under investigation (Attalea speciosa almond oil gel-cream formulation) 1 (one) once a day, in two 15-day cycles: first with the gel-cream formulation with babassu oil (treatment A) and the second with the gel-cream formulation without babassu oil (treatment B). The moisturizing emulsion did not significantly alter (p> 0.05) the xerotic skin pH of the volunteers, treatment A (11.6 ± 0.1), treatment B (8.8 ± 0.2) and control (11.4 ± 0.2) at week W7, when compared to week W15, treatment A (11.0 ± 0.4), treatment B (11.6 ± 0.1) and control (11.4 ± 0.2). Clinical evaluations showed the efficacy and good tolerability of topical emulsion in the hydration of xerotic skin. The biophysical evaluation of the moisturizing emulsion proved the significant improvement of skin moisture.

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 (
