Abstract

The seafood processing industry is bringing in a lot of waste every year around the world. However, crustacean’s residues contain valuable compounds such as calcium carbonate that could potentially be used as a sunscreen. Thus, Polymesoda erosa shells were discovered and calcium carbonate was synthesized for the use in dermal applications. The properties of Polymesoda erosa shells have been characterized by Fourier Transform Infrared Ray (FTIR) and Cytotoxicity tests. Emulsions were formulated and tested on Visible Ultraviolet (UV-Vis) Spectroscopy. The results showed the shells that were dissolved with MnCl2 portrayed a higher tendency to be sun-protective than FeO and the unmodified shell. Therefore, the use of waste from Polymesoda shells will not only add value to the by-products, but also help reduce environmental. Therefore, the formulation of emulsions synthesized from crustacean’s shells is designed as a new hybrid in cosmetics products and improves the skin's protective efficacy against UV rays.
