Coating naoparticles to make them safe for sunscreens

Abstract:
A polymer coating may protect against possible damage that could be caused by nanoparticles used in sunscreens, a scientific study suggests.

Nanoparticles are becoming increasingly popular in personal care products, particularly sunscreens, with the Woodrow Wilson nanotechnology consumer products inventory database counting over 27 sun care products.

However, the use of this technology is becoming increasingly controversial. Of particular concern is how the nanoparticles of sunscreen compounds such as titanium oxide react to UV radiation.

Research suggests that on exposure to UV light titanium oxide emits a photoelectron. It has been suggested that these photoelectrons could go on to catalyse the production of reactive oxygen species, which are known to react with DNA, causing damage.
