Can anyone help me with calculating saponification value based on fatty acids? Is it possible at all?
We have a product in grocery stores here called Flott Matfett. That is a mixed product containing (in falling order): Shea fat, coconut oil, rapeseed oil.
It is used for deep frying baked goods like "smultringer", which is a norwegian type of donut. So this plant based product is meant as an alternative to lard.
I mailed the company and asked for the exact percentages of different oils. They could not give me that. But they could give me the what fatty acids it contain and how much.
I have tried to find it out by using a lye calculator, but it did not match whatever I did. I guess this shea fat is not the same as shea butter. Well, I'm quite sure about that. And the rapeseed oil is most likely high-oleic and maybe hardened in some way. It is a frying fat.
I want to use it for soaping, but need to find a sap. value, or at least an approximate one. I want to use it because it is available. And the only locally available shea fat. Plus I get coconut for bubbles as well. And it does not contain very much rapeseed.
Lauric C12 13 %
Myristic C14 5 %
Palmitic C16 8 %
Stearic C18 29 %
Oleic C18:1 33 %
Linoleic C18:2 5 %
Linolenic C18:3 0,5 %
Saturated - 58%
Mono-unsaturated - 33%
Poly-unsaturated - 5%
Yes, it's not shea butter it contains, most likely. But something cheaper they call shea fat. But who cares since it will be saponified anyway. So I don't think it has to be the most exclusive, especially not for cold process where you can't deside what and what not to add as a superfat.
Because of the limited availance here for everything, it would be great to be able to use it instead of having to only rely on orders from abroad. I want to try this fat combined with some olive oil, it may make a nice and gentle soap, I hope
