I use liquid goat's milk (store brand w/ kefir), but I didn't substitute it for full amount of my water, i substitute aloe vera juice for portions of my water and added in 16 oz of goat's milk--b/c confusion came i mistook milk fat (bovine) sap value as sap value for cow's milk, only i'm using goat's milk--at light trace. So I'm thinking the sap values have to be similar right...So that why I added in full amount of goat's milk that I had measured out...I didn't do a zap test after I brought oils/lye solution to thick puddling texture, I was tired and pour everything in mold even though I was attempting CPHP...
I mean it turn out fine and it has a nice bubbly creamy lather from the small piece i cut off and use to wash my hands...
