Oh dear - I forgot two of my oils :-(
My usual recipe of 1000g oils calls for 139g lye, with a 3% superfat.
Today, I used only 900g oils, but with the same amount of lye. If I recalculate the amount of lye I would need for 900g of oils with 0% superfat, it says 130g. So I used 9g extra of lye than is safe.
The oils I forgot were Avocado and Castor (50g each).
Can someone help me to figure out if this is going to be OK? I used 190g water (filtered coffee) in the recipe and 150g Coconut cream.
I have never calculated for the additional fat in the coconut cream in my recipe, I just use a 3% superfat and figure that the additional fat in the cream will probably push that superfat amount up a bit. I do use less water though, to compensate for the water in the cream.
The can says the cream contains 82% coconut solids, and per 100ml it contains 21.3g total fat, of which 15.5g is saturated. So if I used 150g that's almost 32g additional fat that was not included in my recipe calculation. However, I omitted a total of 100g fat. If I put 32g of CO into Soap Calc, it says I need 5.86g of NaOH to saponify it. So actually I have only used 3.14g more than I should for a 0% superfat.
My lye is 98% NaOH.
Do you think it will be OK with a long cure?
Thank you for taking the time to help me with this.

But it looks like you have pretty much figured it out! You might as well let it cure and see. Maybe keep it for personal use? I imagine it will be a bit brittle, maybe not super pleasant for bath soap. Use it for dish soap? Shred and use for this month’s challenge?
. Maybe that’s what saved me?
