Exposure of pregnant women to certain phenols may disrupt growth of boys during fetal development and first years of life (September 3, 2014)
"Medical researchers have found that exposure to certain common phenols during pregnancy, especially parabens and triclosan, may disrupt growth of boys during fetal growth and the first years of life. Parabens are commonly used as preservatives in cosmetics and healthcare products and triclosan are an antibacterial agent and pesticide found in some toothpastes and soaps"

Endocrine disruptors impair human sperm function (May 12, 2014)
"A plethora of endocrine-disrupting chemicals interfere with human sperm function in a way that may have a negative impact on fertilization, according to new research ... the anti-bacterial agent Triclosan used in toothpaste ... showed adverse actions"

In lab tests, the antimicrobial ingredient triclosan spurs growth of breast cancer cells (April 23, 2014)
"Some manufacturers are turning away from using triclosan as an antimicrobial ingredient in soaps, toothpastes and other products over health concerns. And now scientists are reporting new evidence that appears to support these worries. Their study ... found that triclosan, as well as another commercial substance called octylphenol, promoted the growth of human breast cancer cells in lab dishes and breast cancer tumors in mice"

Antimicrobial from soaps promotes bacteria buildup in human noses (April 8, 2014)
"An antimicrobial agent [Triclosan] found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection"

Antibacterial products fuel resistant bacteria in streams and rivers (September 19, 2013)

Chemical in Antibacterial Soap Fed to Nursing Rats Harms Offspring, Study Finds (June 17, 2013)
"A mother's exposure to triclocarban, a common antibacterial chemical, while nursing her babies shortens the life of her female offspring, a new study in rats finds"

Antibacterial Agent Used in Common Soaps Found in Increasing Amounts in Freshwater Lakes (Jan. 22, 201)
A new University of Minnesota study determined that the common antibacterial agent, called triclosan, used in soaps and many other products is found in increasing amounts in several Minnesota freshwater lakes ... the researchers found an increasing amount of other chemical compounds, called chlorinated triclosan derivatives, that form when triclosan is exposed to chlorine during the wastewater disinfection process. When exposed to sunlight, triclosan and its chlorinated derivatives form dioxins that have potential toxic effects in the environment. These dioxins were also found in the lakes.

Triclosan in Cosmetics and Personal Care Products Can Increase Allergy Risk (Nov. 14, 2012)
