Biodegradable Soap Biodegradable Soap For Hair, Body And Clothes?

Biodegradable soap for hair, body and clothes? - biodegradable soap

I go on an expedition, and they told me that I need biodegradable soap for hair, body and clothes, but I can not always find the special soap.

"Can anyone suggest an alternative? Perhaps shower gel would work?

Thanks in advance
