Chemical and physical filters are the active ingredients in many personal care products to block harmful UV rays. However, chemical filters could often trigger skin irritation and link to hormone disruption. Moreover, some of them are toxic to coral reefs. As a safer alternative, conventional physical filters such as titanium dioxide (TiO2) and zinc oxide (ZnO), usually leave unwanted white masks on the skin. The team has successfully developed hollow mineral-based spheres as physical sunblocker. The synergy between TiO2 and hollow structure not only boosts up UV rays blocking power, but also tackles thick texture and unwanted white masks problems. They are safe for both humans and wildlife, and microplastics-free.
Uniqueness and Competitive Advantages:
• Safe to human and wildlife
• Lower the content of physical UV filters in cosmetic formulation
• Non-whitening effect (Tackle the opaque problem)
• Comparable or enhanced SPF power when compared to conventional UV filters
