A recent report on a group of researchers from NTU, Singapore, caught my eye and I decided to write something about nanotechnology in the cosmetics industry. The article, titled "Chemistry of the size of a nanometer in sunscreen, cosmetics, could cause cancer, say the scientists," was published Nov. 29 in Yahoo News. Some time later, another group of researchers approached and said that this was not true and that it was not a cause for concern. So, what should we believe?
Nanotechnology is not new, but it is a term that has been recently mentioned many times to educate the general public. People who have never heard of the term before the last few months think it's a big deal in the world of cosmetic research. And in reality, it is. But not only in cosmetics and beauty. I find it very ironic that the field of beauty and personal care is apparently the one that sparks the most speculation and interest in nanotechnology because nanotechnology itself is extremely useful in many other areas of science. Cosmetics companies use this term to attract potential customers by ensuring that their products are technologically advanced. What people do not realize is that nanotechnologies also generate waves in the field of biomedical science, such as finding a cure for cancer and treating diseases in a non-invasive way.
In the article mentioned above, a group of scientists tells us that zinc oxide in nanometric form could be harmful and cause cancer. Now, this could scare a lot of people with beauty products that contain zinc oxide and, although we could ask the sales assistants if these oxide particles are nano, they probably did not know for sure. . However, I say it is not a concern. First, researchers are still in the early stages of their research. This means that the results obtained are not important enough to ensure that zinc oxide is labeled as a carcinogen. Secondly, if you study yourself, you will see that previous scientific research has shown that zinc oxide in the form of nanoparticles is an antitumor agent that targets cancer cells 1,2,3. So the real question should be: What is the difference between the different groups of cancerous and cancerous nanoparticles of zinc oxide?
Because the investigation is not complete, the experimental procedures can not be revealed. What I would like to know is why the scientists announce their current results while the investigation is not over. Here they tell the world that zinc oxide could cause cancer and be dangerous. It's like I'm telling you that the chocolate cake you're going to eat could be contaminated and cause diarrhea, but more people should eat it so we know it (assuming I've eaten it and I have diarrhea). Lactose intolerance). Maybe they are very excited about their current results, but are not going to tell people things they are not 100% sure of yet. Why do these oxides multiply cells in cell cultures and why do the Hanley and Wang study oxides do exactly the opposite? Is this the method of synthesis? Delivery method? Variations in the shape and size of nanoparticles? Dosage? What are the differences in intra and intercellular interactions?
While nanotechnology in beauty products is a very interesting topic, and a subject on which you can potentially write nonstop, consumers should be more aware of the properties of these ingredients and their capabilities to them. It's never bad to know more about the things you put yourself in, whether it's the latest liquid base or eye cream.
