Stan, I totally share what you say...it's all very correct.
Very true, I used some beef and pork tallow homemade (my friends from turin killed their pig and bull) soap, they also included bones in the one for personal use adding a scouring power thanks to the bones, it produced virtually no foam...but water was indeed soapy and cleaned very well.
Sudsing of laundry soaps:
Not having tried the Zote flakes cannot tell much, but as I could see with the Jelly soaps Like Oro or Alba and marseille flakes, products meant for machine use, sold down here in Italy, I could see them do now produce slightly less foam of what once they used to, Alba and Alga jelly soap is made out totally of coconut oil while others a mixture of palm, olive and coconut, but especially the Alba and while being made with all coconut, produces less foam than before and all the others, and wonder how it's possible...
As said the other flakes and jelly soaps for washers now sold, also seems to foam slightly less of the average grated bar, both ones I make at home and ones I buy, also of course there are bars more pure and less pure as you say, I found out some are made with a quicker processing than others (quicker as they somnehow reduce aging time by perhaps using less alakali and so resulting in reduced/partial saponification of fats so aging and purity of soap, and they finally speed up things by forced air drying, or something similar...this is what I get/imagine by observing the difference of the cheapers among indutrial soaps), some suds up more than others...of course...others you can actually still feel the partial saponification and fat presence in them and does not foam up as well.
So perhaps these machines products are less purified than bars? I cannot see that actually. So I wonder what they changed in the formula/recipe to make them less foamning..since to me they does not appear less pure, or bad made, or partially saponified....just less foaming.
Infact I could not see very big diferences in terms of reduced cleaning also, even though I find better performers the High sudsing grated bars and my own soaps I make.
Being Zote flakes a product meant for washer use, I now wonder if there is a change for the flakes vs their soap bars...like it happens for the ones I mentioned....even though I really don't know what changes actually.
