The development of microemulsion based anodyne ultraviolet (UV) filters incorporated with melaleuca cajuputi extract

Abstract

For the past few decades, herbal sunscreen have brought major attraction due to their beneficial value such as high ultraviolet ray absorption. Besides, it also has great potential to possess antibacterial activity. Due to these advantages, a series of sunscreen formulations with the combination of herbal extracts were proposed. In this study, four formulations were successfully developed with different composition comprises of nonionic surfactant, co-surfactant, water and essential oil of Melaleuca cajuputi as active ingredient. The percentage ratio by weight of surfactant:co-surfactant:water were F1 (28:22:50), F2 (10:10:80), F3 (26:24:50) and F4 (30:20:50). This study was also conducted to explore the ability of M. cajuputi to promote a good anodyne ultraviolet (UV) filter which can lead to improvement in the treatment of sun burn due to the overexposure to UV radiation.
