Nanoparticles - (CCEA)Nanoparticle in sunscreen

Nanoparticulate materials are already common in sunscreens.

• they provide better skin coverage and more effective protection from the sun’s ultraviolet rays.
• nanoparticles may enter cells and cause damage.
• they may also be harmful to the environment.
• they could be more reactive or toxic than bulk material.
• these risks are difficult to determine because nanoparticles have not been in use for very long.
