I love TreeHugger:

The consensus among public health experts is that excessive use of antibacterial agents in household products leads to increased antibiotic resistance as well as other health effects.  (See Hygiene Hypothesis at Wikipedia).  Anyhow, here is a list of stuff that contains the antibiotic triclosan, which has many similar features to the amphibian
hormone 1. 

We���ve all seen the personal care items that proclaim the equivalent of ���Kills Bacteria On Contact,��� or, ���Kills the Germs That Cause Bad Breath.��� There���s a whole conversation we could start about whether sterile lifestyles���the sort that get enforced with bactericides in personal care and cleaning products��� could have an adverse impact on childhood immune system development and allergic response. But, we���ll leave that topic for later. This post is focused on the environmental risk versus the human health benefit of adding the bacteriocide Triclosan to soaps and lotions. (A list of consumer products containing triclosan is presented below.) We're focused on this more narrow question because of a recently studied consequence of triclosan in freshwater environments. Triclosan, widely used in soaps and toothpastes for its ability to kill bacteria, has been found to hasten the transformation of tadpoles into adult frogs. The new research, "published online September 29 in Aquatic Toxicology , is the first to show that triclosan can act as an endocrine disrupter at concentrations found in North American streams... More than 55% of streams examined in 2002 had a median concentration of 0.14 parts per billion (ppb) (Environ. Sci. Technol. 2002, 36, 2322���2329)". The concern is not just with aquatic life, due to triclosan���s structural similarity to thyroid hormones, which orchestrate growth and development in wildlife and humans.

The following partial list of Triclosan-containing personal care products was obtained from the Household Products Database.
