Soap is a remarkably good antibacterial as well. Im on mobile but will try to look up refs for this later. I used to work in this area and a colleague was an expert on antibacterial properties of detergents.

Yes, cell membranes are largely made of phospholipids. Soap can disrupt the membrane and essentially leak the contents of cells.

I'm pretty sure the lipid-dissolving properties of soap kill bacteria by shredding their cell membranes. It's not effective against viruses, but neither is antibacterial soap.

Thanks for the correction.
