| The para rubber tree (Hevea basilensis) is an economically important tropical tree species that produces natural rubber, a valuable industrial raw material. Innovative products that are derived from by-products from the rubber production process, such as seeds, are important for the sustainability of the para rubber industry. Therefore we subjectively assessed para rubber seed oil for its makeup-removal efficacy and developed it into a makeup cleansing product with appropriate quality control measures for the cosmetic industry. The makeup-removal efficacy of para rubber seed oil was analyzed using a validated UV-Vis spectroscopy, which indicated that the oil removed 86.21 ± 2.48% of liquid foundation [relative standard deviation (RSD) = 2.88%]. Therefore,... |
