Hi Thanks so much for all the useful posts on preservatives and I’m looking forward to your naturals class. This morning I overheard a conversation on the “dangers” of parabens. While I get the fear mongering and pseudo science that has surrounded this issue, there was one thing she said that made me wonder….Is there a potential danger from using too many products containing them? By my last count (and I’m somewhat embarrassed to admit this but apparently marketing works…) I use 45-48 products every morning….body wash, perfume, shampoo, conditioner, hair gels and thermal protecting hair sprays, lots of different makeup products, eye cream…deodorant.. serums….you name it. If every product contains parabens, could there be a health effect in that the amount on my body is no longer insignificant? Hope that makes sense. Thanks!
In 2010, the Natural Resources Defense Council forced the FDA to review triclosan after suing them for their inaction. Because the FDA prohibited hexachlorophene , a compound similar to triclosan, Halden and others argued that the FDA should also ban triclosan.  On December 17, 2013, the FDA issued a draft rule revoking the Generally recognized as safe status of triclosan as an ingredient in hand wash products, citing the need for additional studies of its potential endrocrine and developmental effects; impact on bacterial resistance; and carcinogenic potential. 
DHEA is transformed into DHEA-S by sulfation at the C3β position via the sulfotransferase enzymes SULT2A1 and to a lesser extent SULT1E1 .    This occurs naturally in the adrenal cortex and during first-pass metabolism in the liver and intestines when exogenous DHEA is administered orally. [ citation needed ] Levels of DHEA-S in circulation are approximately 250 to 300 times those of DHEA.  DHEA-S in turn can be converted back into DHEA in peripheral tissues via steroid sulfatase (STS).
