retail news in context, analysis with attitude

The Associated Press reports that the US Food and Drug Administration (FDA) issued tentative guidelines last week saying that food and cosmetic companies wanting to use nanoparticles in products “will have to provide extra testing data to show the products are safe.:”

Nanoparticles, the story explains, are submicroscopic engineered particles that “are increasingly showing up in FDA-regulated products like sunscreens, skin lotions and glare-reducing eyeglass coatings.”

According to UnderstandingNano.com, engineered nanoparticles may be able to help fight disease, cure infections, and even help in cancer treatments by being more targeted in their application than traditional treatments.
