Are we seeing the end of the bar soap? It seems that the majority of Americans between 18-24 are choosing liquid soap for the convenience and because they think that bar soap is covered in germs. In 2015, $2.7 billion was spent on liquid body wash which means, conservatively speaking, 270 million plastic bottles ended up in the waste stream. And that’s just body wash. The carbon footprint is about 25 percent more for liquid soap over bar soap. Bar soap doesn’t have more germs than liquid soap either. Researchers in one study contaminated bar soap with bacteria, only to find that the bacteria wasn’t transferred during hand washing.
