Development of para rubber seed oil as the efficient makeup remover

Abstract

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, we developed stable makeup removers containing 40-70% para rubber seed oil. Bio-oil removers containing 50% and 60% oil had the best appearance and texture and were subsequently evaluated for their makeup-removal efficacy. The bio-oil remover with the higher oil content was significantly better at removing makeup (95.26 ± 0.97% removal by the 60% oil compared with 73.88 ± 3.97% removal by the 50% oil). To conclude, para rubber seed oil is a promising new bio-oil for the cosmetic industry, which broadens consumers' choices of bio-oil makeup removers. We believe that the manufacture and quality control of this innovative and efficient makeup remover are feasible on an industrial scale.

Phytochemical, Antioxidant and Antimicrobial Activities of Hevea brasiliensis Leaves Extract

“…In addition, the components of rubber trees can also be used for other purposes, such as natural conservation products from wood, handicrafts from leaves and biodiesel oil from the extraction of rubber seeds (Le et al 2018). Since 2014, Latex, known for its protein removal properties, has been utilized in the production of various cosmetic products (Lourith et al 2014), including makeup-removal (Lourith et al 2020) and hair loss treatment (Lourith et al 2021). The production of rubber continues to result in the creation of various products.…”

Para rubber seed oil: The safe and efficient bio‐material for hair loss treatment

“…12 However, biological activity of the oil that relevant to hair growth induction or suppression of hair loss remained unexplored. Taken into account on high natural product demand, 11 especially those of bio-oils 13,14 containing linoleic and oleic acids that capable to combat hair loss are to be used substantively on minoxidil and dutasteride, which posed adverse effects. 7 In this presenting context, activity of the oil on antioxidant, proliferation, and inhibition against 5α-reductase in cell cultures was examined.…”
