What are th biodegradable components of soap?

I've been studying biodegradable soap for a field studies project. Somethings you might like to know are: *When camping or backpacking you should at least be 200 feet away from any kind of water source such as lakes, rivers and streams. *When disposing of soapy water while camping or backpacking you should dig at least a 6 inch hole and place the water in the hole. This helps it biodegrade faster. I hope this kind of helps you!
