for a little throwback but with a new twist - nanoparticles in cosmetics. how the plastic packaging of cosmetics with new materials can help protect + preserve the cosmetics it contains. 

Do you think people should be concerned - or it's just the media sensationalizing another possible harmful effect that in fact we have no reason to worry about?

maybe we should look at the chemistry behind simvastatin - how it can penetrate the skin? after that it's a lot of biology 

Yeah that's what I was worried about. And good idea!

People often forget that cosmetics also encompasses things that benefit your health as well. I made one blog post already about how anti-aging creams work but I never looked at foundation and other products.

Article on easier way to make acrylic acid polymers which, after I looked it up, is actually used in a lot of cosmetic products. This may be relevant to what we're studying now because it mentions emulsifying agents (connected to colloids). 

interesting to look at the chemistry of green science especially in the field of cosmetics

Another article - this time more recent. This shows just how much nano-chemistry is prevalent in today's world of cosmetics that they are now making it mandatory in the EU to label products as "nano" to inform the consumer about the possible health risk. 

This article is from 2006. Although a bit dated, it is still worth reading. It poses the possibility of health risks of nano-cosmetics which we know gold colloids utilize.
