Please keep in mind that many people have different opinions on what constitutes a "toxic" chemical. Science generally does not support much of the claims that you state. I prefer to deal in science, not fear.
Was you mother part of a scientific study that showed that her tumors were, in fact, caused by said "regular" products? Strangely enough, my mom had many comments on how wonderful her skin looked during her agressive chemotherapy while using Mary Kay (which I would assume you would define as "regular" product). No new tumors for her. Obviously, this isn't a scientific approach to proving or disproving.
Perhaps your customers would appreciate a more factual and less fear-based marketing approach. I know my customers do (I'm an independent consultant for a "regular" line --just for the sake of being fair).
I tend to doubt websites that site EWG as a credible source personally. The same webpage also discourages getting a routine mammogram screening, and ironically, I am leaving to get my mammogram today (you will notice Cole, that I had previously ignored your rather rude comments regarding me being dishonest about my mother's breast cancer).

Here are a few opinions regarding the EWG. I enjoy www.personalcaretruth.com as well.
