Super Fat Issue - Web App

[kcryss]

I changed the super fat in a recipe I am making right now, but it didn't change the amount to use. I tried deleting cache/cookies and tried again, did not solve the problem. For now I can just calculate on my own what is needed but wanted to report the bug.
Ex: Had originally set sf to 4, result was 20 grams needed. Decided to go with 2% and it did not change. Still showing 20 grams.

Can you give me the name of the recipe so I can look into this? Thank you!

I’m doing some testing, and it seems to be working fine.
Keep in mind that changing the superfat amount doesn’t change the amount of oils you use in a batch if you specify the amount of oils you want. For example, I’m doing a 25 ounce (oils) batch that fits my mold.

In the first photo, it’s a 5% superfat.


I’m making the same size batch, but this time it’s a whopping 25% superfat.


You can see that the amount of oils hasn’t changed a bit- it’s still a 25 ounce batch. But the lye has significantly decreased in the 25% superfat.
Superfat is sometimes called a ‘lye discount’ because less lye is used in the same sized batch for a higher superfat (more fat unsaponified because of less lye).

If you’re doing the superfat after cook, however, that does add some oil after the cook and you can see that addition in the results:

But shouldn't the amount change for superfat after cook?
The recipe is the most recent, mechanic soap apr23_2

Well, yes, it does.
Look at the amounts of the oils.

So you add 40 grams of your chosen superfat after cook. You didn’t not say which superfat you are using under #4, but it does have the amount.
