Fatty acid profile

No verified fatty acid profile is available for neatsfoot oil, so this page shows saponification values only. The lye and water maths do not depend on the profile — only the quality estimates do, and inventing numbers to fill the gap would make those estimates worse, not better.

If you have a sourced profile for this one, send it over and it will be added.
