As far as what properties it brings to the soap i really cant say as im no soap connisuer, all i know is its really nice stuff. My mom is the soap maker. Sometimes i kill a bear and its really hot out and im a long ways from my vehicle and ill leave the fat behind because my number 1 priority is getting the meat out on time to prevent it spoiling in the heat, and the fat is lower priority. My mom chews my ass if i dont save the fat. But when its pushing a hundred degrees out and you have a long packout, sometimes you gotta just worry about the more important shit. Im only going to get 1 fall bear this year though so ill have to make damn sure to save the fat, no excuses.
