ISSN 2588-0764 2588-0764 Production of liquid soap with vegetable oil from ungurahua (Oenocarpus bataua) and essential oils from lemon verbena (Cymbopogon citratus). https://revistas.utm.edu.ec/index.php/Basedelaciencia/article/view/6490 The formulation of liquid soaps from Amazonian vegetable oils combined with essential oils can contribute to the sustainable development of the Ecuadorian Amazon region. Therefore, the objective of the present study was to elaborate a liquid soap using ungurahua oil (Oenocarpus bataua) and the essential oil of hiervaluisa (Cymbopogon citratus) as raw material, with antioxidant properties and potential for use in the cosmetic industry. The saponification of a mixture of O. bataua oil and C. citratus essential oil was carried out using KOH. A 22-factorial design with three central points and two replicates was applied to evaluate the effects of temperature and time on the saponification yield. Total polyphenol content (TPC) was determined by the Folin-Ciocalteau method and antioxidant activity was determined by the Ferric Reducing Antioxidant Power Assay (FRAP). The yield of C. citratus essential oil was 0.48%. This essential oil presented a significant TPC and antioxidant activity. The analysis of the applied factorial design showed that temperature had a significant effect on the soap paste yield, while time and time-temperature interaction were not significant factors. The liquid soap made from the soap paste, with the addition of lemon verbena essential oil, retained total polyphenol content and antioxidant activity. In addition, the physicochemical parameters of the liquid soap comply with the values established in INEN 850, which confirms the adequate quality of the product.

Quantitative research with a sample of 96 students from different disciplines surveyed through the application of questionnaires. The data were subjected to analysis using a Chi-square test; emerging that there is a significant relationship between extracurricular activities and the academic performance of students. This showed that those who carry out extracurricular activities have a better performance in their grades than those who do not carry out the same, whether sports, clubs, volunteering, arts, etc. It was also shown that the typeof extracurricular activity would measure student performance; for example, students who practice these artistic disciplines have a better performance in courses related to creativity. The findings also support what was done by predecessors that AECs support formal academic learning and that, through these practices, students develop time management skills and become more resilient. From the above discussion, it can be concluded that institutions should establish attractive extracurricular programs for all their students to enhance better performance in studies. On the other hand, research is only a small contribution to the topic at hand; further investigation and follow-up are needed to clearly show a causal relationship with the topic at hand. In short, AEC should be included in the university curriculum for the sake of student success and proper skill acquisition.
