When people post recipes or post about the soap they made, do they typically account for how fresh the lye is (old or improperly stored lye == lye discount) and give a really accurate SF%? Or do they assume the NaOH is pure? In other words, when someone writes "5% SF", for most people does that really mean 10% SF? I ask because I bought a bag of fresh NaOH from my local chemical store, and they said it was dry. I stored it in an airtight box with chemical dehumidifiers. The soap I made with this new NaOH is all too drying, or at best borderline. My soaps have typically been around 25% coconut oil. My first batch (also with 25% CO), which I made with super old lye, must have had a huge lye discount due to age, and it is quite good. Is the correct solution to use lower coconut oil or higher superfat? Or to ask the simplest way: when someone says they like "5% superfat" on this forum, does that actually mean 10-15% unless it's written by a chemist type of person?
