I've mostly been planning castile bars, but I'm a bit intrigued by beef tallow and lard in soap. I see a lot of people on this forum swear by lard in their soaps, but I read early on in my research somewhere that lard has low lather. I'm looking at their fatty acid content and their "properties" on Soapee and they don't seem super different, except beef tallow has a smidge more linoleic and lauric acids. I'm curious to hear some personal accounts/experience with these fats. Which do you prefer out of the animal-derived fats? I seem to not see lard used as much as tallow in big commercial brands too; Ivory comes to mind. When you DO use an animal fat (in the case that you don't use it for every single soap you make), what kind of properties do you associate it with adding to a bar? Like for a nice bubbly body soap bar? Or a facial soap bar? I imagine pure beef tallow soap was a common laundry bar once upon a time.
