This article says that scientists have found evidence that a model who used a great deal of cosmetics (concealer, foundation, corrective makeup) in her career are to blame for the birth defects to her son, (the phthalates in most of the cosmetics). Maybe we can find more articles that result in someone suffering defects due to phthalates.

Would providing a list of, for lack of a better word, 'side effects' be a possibility for make-up companies? Perhaps adding something like a long-term effects list.

It's true that companies should test their products for long term effects, however, realistically, that would be VERY expensive, and by then that product may not be "hottest thing out there." An idea could be that we could look into the business aspect of producing cosmetics. For example, the costs in getting the materials together, testing it, marketing, etc.

We can relate this post on hydrolysis and what we just did this past chapter with solutions.

Going off of what Katie said about soaps removing the oils on you skin, I know some people who have really sensitive skin and actually break out into rashes after using certain soaps. Maybe we can look why that happens, (is it the removal of oils, or the addition of chemicals that are supposed to help moisturize the skin). From there we can probably find the ingredient that leads to such effects.

Maybe we can go even further and see if it is the different combinations of ingredients that causes reactions. Perhaps it may be the case that one ingredient may be harmless if it is alone, but when combined with something else, it can change its properties.

I don't know if we could actually take anything from this site, but it's a really good place start looking into. It seems that triclosan and Sodium Lauryl Sulfate are big issues that can be further researched. They are very likely to be found in other body cleansing cosmetics.

This article talks about breast cancer and parabens, but I think that information about parabens alone could be a very good topic to discuss.  Parabens are found in many shampoos, moisturizers, deodorants, gels, etc. 

Looking even from the abstract, we can get some info on abutin - the chemical in the gold mask that cause irritation
