Seems I do best with Dr. Alkaitis Organic products as they are food grade and gentle, but they are expensive.
I was using Mrs. Meyers Clean Day hand soap but found the chemicals are not that great so, I just found a whole body natural soap on amazon smile.... Nutribiotic Pure Coconut Oil Soap, Unscented, 128 Fluid Ounce >
https://smile.amazon.com/gp/product/B004ZC8JOI/ref=ppx_yo_dt_b_asin_title_o01_s03?ie=UTF8&psc=1It seems pricey, but it's a gallon which will last me a long time. It's very thin so a foaming soap dispenser would be good to use. I am tempted to add some organic vegetable glycerin and make it thicker and go farther.
I find it extremely gentle.
I also recently used Pear's glycerin soap and it did not cause a reaction or dryness (that I noticed).
