Nanotechnology in your sunscreen!

Here's one place you didn't expect to find application of nanotechnology: your sunscreen . And here's one place you might have been surprised to find leading the race for scientific innovation in this sector: Mexico. Maybe it's because they've got a lot of sun. From the article:

A high-tech dispersion physicochemical process was designed, which will ensure that the nanoparticles remain stable in the formulation of the final product. The advantage in the cosmetic formula is that using titanium dioxide nanoparticles increases the photo protective efficacy, since it has been demonstrated that the lower the particle size the better the protective UV efficiency. In addition to the cosmetic industry, the company seeks to implement the nanoparticles on other products, such as waterproofing paints, coatings and plastics, because it improves resistance to environmental exposure.

The cosmetics industry – and sunscreen is a part of it – is one of the most competitive sectors in the market, and the race to identify new products and processes is a high-intensity one. Bonus: innovative sunscreen will lead to some sexy new advertisement. Unlike nanotech laboratory gloves.
