Zinc Oxide, Nanotechnology and Cosmetics

A recent report about a group of researchers in NTU, Singapore, caught my attention and I decided to write something about nanotechnology in the cosmetics industry. The article, titled “Nano-sized chemical in sunscreen, cosmetics, could cause cancer, say scientists,” was published November th on Yahoo News. A while after that, another group of researchers came up and said that this isn’t true and that it isn’t a cause for concern. So what should we believe? Nanotechnology isn’t new but it is a term that has been recently brought up time and again to raise awareness amongst the general public.

People who have never heard of the term prior to recent months think that this is a great deal in the world of cosmetic research. And actually, it is. But not just in cosmetics and beauty. I find it highly ironic that the field of beauty and personal care should seemingly be the one that generates the most speculation and interest in nanotechnology because nanotechnology itself is extremely useful in many other areas of science as well. Cosmetic companies make use of this term to entice potential customers by making their products sound technologically advanced.

What people don’t realise is that nanotechnology is making waves too, in the field of biomedical science, such as finding a cure for cancer and treating Maintaining the Highest of Standards illnesses via the non-invasive way. In the article mentioned above, a group of scientists are telling us that zinc oxide in the nano form could be harmful and cause cancer. Now this could scare many people off beauty products that contain zinc oxide and while we could ask sales assistants whether these oxide particles are nano-sized, the chances are that they wouldn’t know for sure.
