@candy52 Thank you for the insight and explanation. Hopefully since it’s just the pumice and suspension base, it will not alter the soap. I will definitely start slow to see how it affects the premade soap base. I’m just confused as to what type of suspension base I can use so that it is compatible with my ingredients (does it matter?). This is where I’m lost. I have reached out to manufacturers to get my hands on Carbopol Aqua SF-1 polymer, but I’m not even sure if this is the correct suspension/thickening base to mix in.
