Our silica-titania hybrid hollow spheres are an innovative solution to the microplastics issue and health concerns associated with conventional UV filters in sunscreen. Composed of inorganic materials, our silica-titania hybrid hollow “O-Spheres SunBlocker” UV filters are coral-friendly. Its unique hollow structure prevents titania particle aggregation, reduces costs, and eliminates the white mask effect. The spherical shape boost UV shielding effect for sun protection with more desirable texture for better user experience. The manufacturing of UV filters has entered the stage of industrial mass production, and they are about to be launched in the local and Asian markets.
