I am using this recipe:

75% olive oil

25% coconut oil

then lets say i want to calculate the percentages of things in my recipe for a 2lb batch:

H20: 344g

NaOH: 127 g

Olive: 680g

Coconut: 226g

Total weight: 1377 g

so that means that I am using

H20: 24.9%

NaOH: 9.22%

Olive: 49%

Coconut: 16%

These numbers are different because it is calculated from the TOTAL weight of ingredients instead of just the oils which would be 75/25....right???

so if I want to calculate how much EO to use (lets say 1.5% of total weight)

I would calculate/use 1377gX1.5% =20.7g (rounded) of EO in the batch??)....right??

just making sure my math is correct because like i said im a little rusty

Thank you to every/anyone who helps!

I dont think Id be able to learn to soap without this forum so serioulsy....MAJOR THANKS TO EVERYONE!
