It is a surfactant, yes. TBH, if I was soaping in an apocalypse, I'd imagine used frying grease would be the last available fat source, not butter. It also doesn't make a pleasant-smelling soap, but for different reasons.
If you're using milk or cream in soap, you'd be fine. Butter unfortunately will stink like feet and it will never go away. One might as well call a butter bar the "Bar of Eternal Stench" and chuck it. There is no saving that soap.
Tallow is animal fat.
I'm with you @Misschief!
My sister did comment that her butter soap lightened her skin a bit. I wouldn't mind it if the soap was fantastic with scar fading but I don't wanna smell like feet cheese either. Yes, you will stink after using that soap and it lingers.
My question is why anyone would want to use butter or ghee to make soap when there are so many other great vegan oils to use. Why use animal products? My soap is the most wonderful soap and I never use animal products. No need to. Also why use FO when you have a bounty of wonderful real healthy EO's that actually help the skin? Just a question, not a slam.
Add vitamin E if you want to make scars fade.
It's wasted in soap. The right vitamin E is great in lotion though.
As Arimara posted in the last post, EO in soap may smell nice but it's generally agreed that the lye monster pretty much takes care of any healing properties.
The EO vs FO question gets hashed and rehashed a lot and has a number of threads dedicated to it. Here is my take: I like the smell of FOs, there are relatively few EOs I like the smell of, FOs are cheaper than the few EOs I like, and I prefer to save my skin-care EOs for lotion and other leave-on products where they will have more influence. And even when I do use EOs for their skin value, I still usually use a complementary FO because, again, I don't enjoy the smell of most EOs. Others can't use EOs because certain ones trigger migraines, skin sensitivities, or other complications, but they can use FOs instead. For some people, FOs trigger the migraines, skin sensitivities, and so on, but EOs don't for them.
Again, I’m with you Misschief. Lard and tallow make wonderful soaps. I am a vegetarian in my daily life, but if the poor animals are butchered already, why throw away the byproducts?
