I used to use Ivory real soap flakes ("Ivory Snow") for hand washing of detergent sensitive items.
But of course that product has long vanished from store shelves.
I have grated Ivory Soap bars in the KA with the grating attachment, and used that sparingly in my Neptune 7500 front load washer. With hot water to help dissolve the grated soap bits. Dosing is tricky, so when I've used it I've added less than one might otherwise think, then check the suds level and add more later if needed to establish a thin layer of suds. I also add STPP at the start of the process, before the soap, to help prevent soap scum. The results were good, but a bit of a bother. It left bath towels softer than with most detergents, but with a sort of rubbery feel that I attribute to residual soap. I also noticed that whites tended to have a more yellow tinge to them after a few washings with the soap gratings, so I went back to my trusty Sears Ultra/STPP mix for them.
I haven't seen the Zote flakes in a market yet. I've grated Zote laundry bar soap as well as the Ivory, with similar wash results.
