Narrator: This is Science Today. A new study found that a common antibacterial chemical called triclocarban, or TCC, which is added to bath soaps and other personal care products, altered hormonal activity in rats and in human cells in the lab. This type of finding can obviously cause alarm among consumers, but Bill Lasley, an expert in reproductive toxicology at the University of California, Davis says consumers should not panic.
Lasley: People phone and they say, oh my goodness - I've just looked and I've been using this for a long time. Should I be concerned and should I change products? And the simple answer is - it really can't be that bad or it wouldn't have taken us this long to discover that this had the potential.
Narrator: Lasley says an increase in hormone activity could be linked to early puberty, Type 2 diabetes, enlarged prostate disease and pre-term labor.
Lasley: I don't think that anyone should worry that in the next few months or years that anything serious is going to come of this, but we could slow down some of the progressive diseases that we see if we understand this better - and that would be good.
