The invention relates to a method for producing nano-hydroxyapatite from the waste fish scale. Nano-hydroxyapatite has excellent biocompatibility is very suitable for make cosmetics and biomaterial, we applied this material in various sorts of cosmetic, resulting in many unique effects. Nano-hydroxyapatite has a high refractive index and good coverage, it will enhance the UV light scattering and shielding, it can significant protect the skin.
