Looking for more biocompatible sunscreen ingredients in pharmaceutical and cosmetic formulations - Myriam Rincon Fontan, L Rodriguez-Lopez, A Lopez-Prieto, X Vecino, J M Cruz and A B Moldes - University of Vigo, Spain

Statement of the Problem: Nowadays, cosmetic and pharmaceutical industries are looking for more natural ingredients to prevent the effects of sun damaging radiation (UV light) on skin. Usually, sunscreen formulations contain synthetic organic compounds, which can produce irritant effects on skin. Therefore, there is a need for the use of more natural and biocompatible ingredients. The utilization of a biosurfactant extract obtained from corn in combination with mica, could be an interesting alternative to replace chemical sunscreen ingredients. Additionally, vitamin E could be included as well in these formulations because of its antioxidant capacity. In this work, it is elucidated that the sun protection factor (SPF) and emulsion formation (EV) of different formulations were formed by a biosurfactant aqueous extract (obtained from corn), a mining silicate mineral (mica) and a non-aqueous soluble antioxidant (Vitamin E). Methodology: Different formulations were prepared in presence and absence of biosurfactant, in order to see the effect of it as sunscreen and emulsifier. The SPF of each substance and of the different formulations was measured following the methodology of Mansur et al. using ethanol as solvent. On the other hand, the percentage of emulsion formation (EV) was measured as in previous studies, during one month. Findings: It was shown that all substances tested exerted sun protection capacity. Particularly, the biosurfactant showed a better SPF than tocopherol, at the same concentration. As a consequence, the presence of the biosurfactant increased the SPF of the different formulations. Moreover, this biosurfactant was observed to exert emulsifier capacity during the experiment. Conclusion & Significance: The preparation of formulations in presence of biosurfactant, mica and tocopherol can be a good alternative to obtain more biocompatible sunscreen formulations for the cosmetic and pharmaceutical industry, observing a synergistic effect of mica and biosurfactant on the stabilization of the emulsions.
