Triathlon Training: Effects of Chlorine

I have a few questions for you experts (or self reflecting types) on pool swimming.  What are the effects of chlorine?  It gets in my head a little because I’m well aware that Skin is the body’s biggest organ.

I try to get a good soap shower afterwards, but can often smell the the chemicals late into the night.  Is there a special soap/shampoo I should be using?  Has anyone felt like they’ve experienced chlorine detox during the day?  Good swim caps?  Pre-swim body apps?  Any other thoughts on this topic?
