I was just reading about that online and I THINK there is an equine-type shop down the road from me! I'm not quite in horse-country, but close. I've never been in that store, so I'm not positive it's an equine store but it looks like it should be. I'll try it! Thanks everyone!
It does have a saponification value that can be found in the soap calculator. However, I use mine for superfatting. I have read that in order for it to be most beneficial it should be added at 20%. I do that on top of my regular recipe.....but I think it smells horrible.
