Biomaterials derived from Tamban, Sardinella Fimbriata bones as promising Anodyne sunscreen

Development in the fish processing industry has led to a large amount of waste including, fish head, scales, bones and guts, every year around the world. Certain fish bones have an attractive added value which contains hydroxyapatite (HAP), (Ca10(PO4)6(OH)2) that can potentially be used as UV absorbance (unmodified bones). Sardinella fimbriata bone was synthesized and utilized as sunscreen in cosmeceuticals with the addition of manganese and ferum, new hybrid sunscreen materials have been initiated via hydroxyapatite-Fe and hydroxyapatite-Mn doped (modified bones).The modified bones have been characterized using Nuclear Magnetic Resonance (NMR) spectroscopy and X-Ray Diffraction (XRD) and UV-Visible spectroscopy. The results clearly indicated that the HAP existing in the waste of S. fimbriata bone exhibits high potential as sunscreen with addition of FeCl2 compared to manganese and unmodified Tamban bones. Thus, the utilization of waste from the fish bone not only produce value-added products from lowcost resources, but also help in reducing pollution to the environment and preserve the global sustainability
