The answer is Tabac.
I must say despite me constantly inserting Tabac comments everywhere I go, I do also use Haslinger non tallow soap.
I only tried it out of curiosity because of claims it was as good as their discontinued tallow version. I do like it enough to continue using it. Tabac and Haslinger are all I use now, and that from someone who previously believed tallow was the only way to go.
I do like tallow soaps but I have one problem with them. Because of the high fat content in them I find they tend to clog my sink up. I have to run a snake thru my drain about every 2 years.
Now I try to use soaps that contain SLS (sodium laureth sulfate). It helps to improve the separation of and to prevent settling or clumping.
You might want to try this about once a month - put a generous squeeze of Dawn or equivalent dishwashing liquid in the drain, let it sit for an hour and then flush the drain by running just the hot water.
