Can I substitute duck for other animal fat?

[janesathome]

Hi! I’ve been looking through the table of different fats and oils, and I see “duck - fat, bones and skin” . I have some rendered duck fat that I’d like to include in a batch of soap, but I sure don’t want to incorporate bones and skin! Does anyone know if duck and goose fat are similar enough that I could just load goose fat into the calculator?
Thank you, soapy people!

If you look on Soapmakingfriend.com, their listing for duck fat says "flesh and skin" with a .138 N-SAP I take that to mean that the fat came from the flesh and the skin - because flesh and skin aren't oil. So I would use the duck fat listing as-is.

But I'll be honest, I save all my duck fat for cooking - so yummy!

I couldn’t remember whether it was “flesh” or “bones” - thanks for the correction! Either way … NOPE! .
I have been using my duck fat for cooking too, but have to lower my cholesterol so figured I’d put the duck fat ON my skin instead of under it
I appreciate your help
